Attributes:

  • Requires a Maven project to be executed.

Optional Parameters

Name Type Since Description
encoding String 2.5 The file encoding of the source files.
Default value is: ${project.build.sourceEncoding}.
User property is: encoding.
extractors Set 2.4 The role names of mojo extractors to use. If not set, all mojo extractors will be used. If set to an empty extractor name, no mojo extractors will be used. Example: 
 <!-- Use all mojo extractors -->
 <extractors/>

 <!-- Use no mojo extractors -->
 <extractors>
     <extractor/>
 </extractors>

 <!-- Use only bsh mojo extractor -->
 <extractors>
     <extractor>bsh</extractor>
 </extractors>

goalPrefix String 2.4 The goal prefix that will appear before the ":".
helpPackageName String 2.6 The name of the package for the generated HelpMojo. By default, the package will be calculated based on the packages of the other plugin goals.
mojoDependencies List 3.5 Specify the dependencies as groupId:artifactId containing (abstract) Mojos. If not specified in the configuration, this is null and all dependencies are scanned. If specified with no children, no dependencies are scanned.
outputDirectory File 2.4 The directory where the generated HelpMojo file will be put.
Default value is: ${project.build.directory}/generated-sources/plugin.
packagingTypes List 3.3 Maven plugin packaging types. Default is single "maven-plugin".
skip boolean 2.8 Set this to "true" to skip invoking any goals or reports of the plugin.
Default value is: false.
User property is: maven.plugin.skip.
skipErrorNoDescriptorsFound boolean 3.0 By default an exception is throw if no mojo descriptor is found. As the maven-plugin is defined in core, the descriptor generator mojo is bound to generate-resources phase. But for annotations, the compiled classes are needed, so skip error
Default value is: false.
User property is: maven.plugin.skipErrorNoDescriptorsFound.
