[INFO] org.apache.maven.plugins:maven-war-plugin:3.1.0

Name: Apache Maven WAR Plugin
Description: Builds a Web Application Archive (WAR) file from the project
  output and its dependencies.
Group Id: org.apache.maven.plugins
Artifact Id: maven-war-plugin
Version: 3.1.0
Goal Prefix: war

This plugin has 4 goals:

war:exploded
  Description: Create an exploded webapp in a specified directory.
  Implementation: org.apache.maven.plugins.war.WarExplodedMojo
  Language: java
  Bound to phase: package

  Available parameters:

    archive
      The archive configuration to use. See Maven Archiver Reference.

    archiveClasses (Default: false)
      Whether a JAR file will be created for the classes in the webapp. Using
      this optional configuration parameter will make the compiled classes to
      be archived into a JAR file and the classes directory will then be
      excluded from the webapp.

    cacheFile (Default: ${project.build.directory}/war/work/webapp-cache.xml)
      Required: true
      The file containing the webapp structure cache.

    containerConfigXML
      The path to a configuration file for the servlet container. Note that the
      file name may be different for different servlet containers. Apache
      Tomcat uses a configuration file named context.xml. The file will be
      copied to the META-INF directory.

    delimiters
      Set of delimiters for expressions to filter within the resources. These
      delimiters are specified in the form 'beginToken*endToken'. If no '*' is
      given, the delimiter is assumed to be the same for start and end.
      
      So, the default filtering delimiters might be specified as:
      
      <delimiters>
        <delimiter>${*}</delimiter>
        <delimiter>@</delimiter>
      </delimiters>
      
      Since the '@' delimiter is the same on both ends, we don't need to
      specify '@*@' (though we can).

    dependentWarExcludes
      The comma separated list of tokens to exclude when doing a WAR overlay.
      Default is Overlay.DEFAULT_EXCLUDES

    dependentWarIncludes
      The comma separated list of tokens to include when doing a WAR overlay.
      Default is Overlay.DEFAULT_INCLUDES

    escapedBackslashesInFilePath (Default: false)
      To escape interpolated values with Windows path c:\foo\bar will be
      replaced with c:\\foo\\bar.

    escapeString
      Expression preceded with this String won't be interpolated. \${foo} will
      be replaced with ${foo}.

    filteringDeploymentDescriptors (Default: false)
      To filter deployment descriptors. Disabled by default.

    filters
      Filters (property files) to include during the interpolation of the
      pom.xml.

    includeEmptyDirectories (Default: false)
      (no description available)

    nonFilteredFileExtensions
      A list of file extensions that should not be filtered. Will be used when
      filtering webResources and overlays.

    outputFileNameMapping
      The file name mapping to use when copying libraries and TLDs. If no file
      mapping is set (default) the files are copied with their standard names.

    overlays
      The overlays to apply. Each <overlay> element may contain:
      - id (defaults to currentBuild)
      - groupId (if this and artifactId are null, then the current project is
        treated as its own overlay)
      - artifactId (see above)
      - classifier
      - type
      - includes (a list of string patterns)
      - excludes (a list of string patterns)
      - filtered (defaults to false)
      - skip (defaults to false)
      - targetPath (defaults to root of webapp structure)

    recompressZippedFiles (Default: true)
      Indicates if zip archives (jar,zip etc) being added to the war should be
      compressed again. Compressing again can result in smaller archive size,
      but gives noticeably longer execution time.

    resourceEncoding (Default: ${project.build.sourceEncoding})
      The encoding to use when copying filtered web resources.

    supportMultiLineFiltering (Default: false)
      Stop searching endToken at the end of line

    useCache (Default: false)
      Whether the cache should be used to save the status of the webapp across
      multiple runs. Experimental feature so disabled by default.

    useDefaultDelimiters (Default: true)
      Use default delimiters in addition to custom delimiters, if any.

    useJvmChmod (Default: true)
      use jvmChmod rather that cli chmod and forking process

    warSourceDirectory (Default: ${basedir}/src/main/webapp)
      Required: true
      Single directory for extra files to include in the WAR. This is where you
      place your JSP files.

    warSourceExcludes
      The comma separated list of tokens to exclude when copying the content of
      the warSourceDirectory.

    warSourceIncludes (Default: **)

      the warSourceDirectory.

    webappDirectory (Default:
    ${project.build.directory}/${project.build.finalName})
      Required: true
      The directory where the webapp is built.

      Required: true
      Directory to unpack dependent WARs into if needed.

war:help
  Description: Display help information on maven-war-plugin.

      If true, display all settable properties for each goal.

    goal
      User property: goal
      The name of the goal for which to show help. If unspecified, all goals

      The number of spaces per indentation level, should be positive.

    lineLength (Default: 80)
      User property: lineLength
      The maximum length of a display line, should be positive.

war:inplace
  Description: Generate the webapp in the WAR source directory.
  Implementation: org.apache.maven.plugins.war.WarInPlaceMojo

  Implementation: org.apache.maven.plugins.war.WarMojo
  Language: java
  Bound to phase: package

  Available parameters:

    archive
      The archive configuration to use. See Maven Archiver Reference.

    archiveClasses (Default: false)
      Whether a JAR file will be created for the classes in the webapp. Using
      this optional configuration parameter will make the compiled classes to
      be archived into a JAR file and the classes directory will then be
      excluded from the webapp.

      should be attached to the project as an additional artifact.
      By default the classifier for the additional artifact is 'classes'. You
      can change it with the someclassifier parameter.

      attachment instead. The classifier will not be applied to the JAR file of
      the project - only to the WAR file.

    containerConfigXML
      The path to a configuration file for the servlet container. Note that the
      file name may be different for different servlet containers. Apache
      Tomcat uses a configuration file named context.xml. The file will be
      copied to the META-INF directory.

    delimiters

      specify '@*@' (though we can).

    dependentWarExcludes
      The comma separated list of tokens to exclude when doing a WAR overlay.
      Default is Overlay.DEFAULT_EXCLUDES

      Default is Overlay.DEFAULT_INCLUDES

    escapedBackslashesInFilePath (Default: false)
      To escape interpolated values with Windows path c:\foo\bar will be
      replaced with c:\\foo\\bar.

    escapeString
      Expression preceded with this String won't be interpolated. \${foo} will

    failOnMissingWebXml
      Whether or not to fail the build if the web.xml file is missing. Set to
      false if you want your WAR built without a web.xml file. This may be
      useful if you are building an overlay that has no web.xml file.
      Starting with 3.1.0, this property defaults to false if the project
      depends on the Servlet 3.0 API or newer.

    filteringDeploymentDescriptors (Default: false)
      To filter deployment descriptors. Disabled by default.

    filters
      Filters (property files) to include during the interpolation of the
      pom.xml.

    includeEmptyDirectories (Default: false)
      (no description available)

      - excludes (a list of string patterns)
      - filtered (defaults to false)
      - skip (defaults to false)
      - targetPath (defaults to root of webapp structure)

    packagingExcludes
      The comma separated list of tokens to exclude from the WAR before
      packaging. This option may be used to implement the skinny WAR use case.
      Note that you can use the Java Regular Expressions engine to include and
      exclude specific pattern using the expression %regex[]. Hint: read the
      about (?!Pattern).

    packagingIncludes
      The comma separated list of tokens to include in the WAR before
      packaging. By default everything is included. This option may be used to
      implement the skinny WAR use case. Note that you can use the Java Regular
      Expressions engine to include and exclude specific pattern using the
      expression %regex[].

    primaryArtifact (Default: true)

      The encoding to use when copying filtered web resources.

    skip (Default: false)
      User property: maven.war.skip
      You can skip the execution of the plugin if you need to. Its use is NOT
      RECOMMENDED, but quite convenient on occasion.

    supportMultiLineFiltering (Default: false)
      Stop searching endToken at the end of line

    useCache (Default: false)
      Whether the cache should be used to save the status of the webapp across

[INFO] org.springframework.boot:spring-boot-maven-plugin:1.5.6.RELEASE

Name: Spring Boot Maven Plugin
Description: Spring Boot Maven Plugin
Group Id: org.springframework.boot
Artifact Id: spring-boot-maven-plugin
Version: 1.5.6.RELEASE
Goal Prefix: spring-boot

This plugin has 6 goals:

spring-boot:build-info
  Description: Generate a build-info.properties file based the content of the
    current MavenProject.
  Implementation: org.springframework.boot.maven.BuildInfoMojo
  Language: java
  Bound to phase: generate-resources

  Available parameters:

    additionalProperties
      Additional properties to store in the build-info.properties. Each entry
      is prefixed by build. in the generated build-info.properties.

    outputFile (Default:
    ${project.build.outputDirectory}/META-INF/build-info.properties)
      The location of the generated build-info.properties.

spring-boot:help
  Description: Display help information on spring-boot-maven-plugin.
    Call mvn spring-boot:help -Ddetail=true -Dgoal=<goal-name> to display
    parameter details.
  Implementation: org.springframework.boot.maven.HelpMojo
  Language: java

  Available parameters:

    detail (Default: false)
      User property: detail
      If true, display all settable properties for each goal.

    goal
      User property: goal
      The name of the goal for which to show help. If unspecified, all goals
      will be displayed.

    indentSize (Default: 2)
      User property: indentSize
      The number of spaces per indentation level, should be positive.

    lineLength (Default: 80)
      User property: lineLength
      The maximum length of a display line, should be positive.

spring-boot:repackage
  Description: Repackages existing JAR and WAR archives so that they can be
    executed from the command line using java -jar. With layout=NONE can also
    be used simply to package a JAR with nested dependencies (and no main
    class, so not executable).
  Implementation: org.springframework.boot.maven.RepackageMojo
  Language: java
  Bound to phase: package

  Available parameters:

    attach (Default: true)
      Attach the repackaged archive to be installed and deployed.

    classifier
      Classifier to add to the artifact generated. If given, the artifact will
      be attached with that classifier and the main artifact will be deployed
      as the main artifact. If this is not given (default), it will replace the
      main artifact and only the repackaged artifact will be deployed.
      Attaching the artifact allows to deploy it alongside to the original one,
      see the maven documentation for more details.

    embeddedLaunchScript
      The embedded launch script to prepend to the front of the jar if it is
      fully executable. If not specified the 'Spring Boot' default script will
      be used.

    embeddedLaunchScriptProperties
      Properties that should be expanded in the embedded launch script.

    excludeArtifactIds
      User property: excludeArtifactIds
      Comma separated list of artifact names to exclude (exact match).

    excludeDevtools (Default: true)
      Exclude Spring Boot devtools from the repackaged archive.

    excludeGroupIds
      User property: excludeGroupIds
      Comma separated list of groupId names to exclude (exact match).

    excludes
      Collection of artifact definitions to exclude. The Exclude element
      defines a groupId and artifactId mandatory properties and an optional
      classifier property.

    executable (Default: false)
      Make a fully executable jar for *nix machines by prepending a launch
      script to the jar.
      Currently, some tools do not accept this format so you may not always be
      able to use this technique. For example, jar -xf may silently fail to
      extract a jar or war that has been made fully-executable. It is
      recommended that you only enable this option if you intend to execute it
      directly, rather than running it with java -jar or deploying it to a
      servlet container.

    finalName (Default: ${project.build.finalName})
      Required: true
      Name of the generated archive.

    includes
      Collection of artifact definitions to include. The Include element
      defines a groupId and artifactId mandatory properties and an optional
      classifier property.

    includeSystemScope (Default: false)
      Include system scoped dependencies.

    layout
      The type of archive (which corresponds to how the dependencies are laid
      out inside it). Possible values are JAR, WAR, ZIP, DIR, NONE. Defaults to
      a guess based on the archive type.

    layoutFactory
      The layout factory that will be used to create the executable archive if
      no explicit layout is set. Alternative layouts implementations can be
      provided by 3rd parties.

    mainClass
      The name of the main class. If not specified the first compiled class
      found that contains a 'main' method will be used.

    outputDirectory (Default: ${project.build.directory})
      Required: true
      Directory containing the generated archive.

    requiresUnpack
      A list of the libraries that must be unpacked from fat jars in order to
      run. Specify each library as a <dependency> with a <groupId> and a
      <artifactId> and they will be unpacked at runtime.

    skip (Default: false)
      User property: skip
      Skip the execution.

spring-boot:run
  Description: Run an executable archive application.
  Implementation: org.springframework.boot.maven.RunMojo
  Language: java
  Bound to phase: validate
  Before this mojo executes, it will call:
    Phase: 'test-compile'

  Available parameters:

    addResources (Default: false)
      User property: run.addResources
      Add maven resources to the classpath directly, this allows live in-place
      editing of resources. Duplicate resources are removed from target/classes
      to prevent them to appear twice if ClassLoader.getResources() is called.
      Please consider adding spring-boot-devtools to your project instead as it
      provides this feature and many more.

      User property: excludeArtifactIds
      Comma separated list of artifact names to exclude (exact match).

    excludeGroupIds
      User property: excludeGroupIds
      Comma separated list of groupId names to exclude (exact match).

      Additional folders besides the classes directory that should be added to
      the classpath.

    fork
      User property: fork

      Current working directory to use for the application. If not specified,
      basedir will be used. NOTE: the use of working directory means that
      processes will be started by forking a new JVM.

spring-boot:start
  Description: Start a spring application. Contrary to the run goal, this
    does not block and allows other goal to operate on the application. This
    goal is typically used in integration test scenario where the application
