Component

When creating several assemblies for a project with a custom assembly descriptor, it can't be helped that you will be duplicating some parts of a defined assembly. These duplicates can be extracted and placed in a separate file called a descriptor component.

Descriptor components contain FileSets, Files, and DependencySets meant to be shared by assembly descriptors by referencing them using <componentDescriptors>. It allows multiple assemblies to share a set of user defined collections.

moduleSet

A moduleSet represent one or more project <module> present inside a project's pom.xml. This allows you to include sources or binaries belonging to a project's <modules>.
NOTE: When using <moduleSets> from the command-line, it is required to pass first the package phase by doing: "mvn package assembly:assembly". This bug/issue is scheduled to be addressed by Maven 2.1.

Element Type Description
useAllReactorProjects boolean If set to true, the plugin will include all projects in the current reactor for processing in this ModuleSet. These will be subject to include/exclude rules. Default value is true. (Since 2.2)
Default value is: false.
includeSubModules boolean If set to false, the plugin will exclude sub-modules from processing in this ModuleSet. Otherwise, it will process all sub-modules, each subject to include/exclude rules. Default value is true. (Since 2.2)
Default value is: true.
includes/include* List<String> (Many) When <include> subelements are present, they define a set of project coordinates to include. If none is present, then <includes> represents all valid values. Artifact coordinates may be given in simple groupId:artifactId form, or they may be fully qualified in the form groupId:artifactId:type[:classifier]:version. Additionally, wildcards can be used, as in *:maven-*
excludes/exclude* List<String> (Many) When <exclude> subelements are present, they define a set of project artifact coordinates to exclude. If none is present, then <excludes> represents no exclusions. Artifact coordinates may be given in simple groupId:artifactId form, or they may be fully qualified in the form groupId:artifactId:type[:classifier]:version. Additionally, wildcards can be used, as in *:maven-*
sources ModuleSources When this is present, the plugin will include the source files of the included modules from this set in the resulting assembly.

excludeSubModuleDirectories boolean Specifies whether sub-module directories below the current module should be excluded from fileSets applied to that module. This might be useful if you only mean to copy the sources for the exact module list matched by this ModuleSet, ignoring (or processing separately) the modules which exist in directories below the current one. Default value is true. (Since 2.2)
Default value is: true.
outputDirectoryMapping String Sets the mapping pattern for all module base-directories included in this assembly. NOTE: This field is only used if includeModuleDirectory == true. Default is the module's ${artifactId} in 2.2-beta-1, and ${module.artifactId} in subsequent versions. (Since 2.2)

includes/include* List<String> (Many) When <include> subelements are present, they define a set of artifact coordinates to include. If none is present, then <includes> represents all valid values. Artifact coordinates may be given in simple groupId:artifactId form, or they may be fully qualified in the form groupId:artifactId:type[:classifier]:version. Additionally, wildcards can be used, as in *:maven-*
excludes/exclude* List<String> (Many) When <exclude> subelements are present, they define a set of dependency artifact coordinates to exclude.

directoryMode String Similar to a UNIX permission, sets the directory mode of the directories included. THIS IS AN OCTAL VALUE. Format: (User)(Group)(Other) where each component is a sum of Read = 4, Write = 2, and Execute = 1. For example, the value 0755 translates to User read-write, Group and Other read-only. The default value is 0755. (more on unix-style permissions)
useStrictFiltering boolean When specified as true, any include/exclude patterns which aren't used to filter an actual artifact during assembly creation will cause the build to fail with an error. This is meant to highlight obsolete inclusions or exclusions, or else signal that the assembly descriptor is incorrectly configured. (Since 2.2)
Default value is: false.
outputFileNameMapping String Sets the mapping pattern for all dependencies included in this assembly. Default is ${artifact.artifactId}-${artifact.version}${dashClassifier?}.${artifact.extension}. (Since 2.2-beta-2; 2.2-beta-1 uses ${artifactId}-${version}${dashClassifier?}.${extension}). NOTE: If the dependencySet specifies unpack == true, outputFileNameMapping WILL NOT BE USED; in these cases, use outputDirectory. See the plugin FAQ for more details about entries usable in the outputFileNameMapping parameter.

useProjectAttachments boolean Determines whether the attached artifacts produced during the current project's build should be included in this dependency set. Default value is false. (Since 2.2)
Default value is: false.
useTransitiveDependencies boolean Determines whether transitive dependencies will be included in the processing of the current dependency set. If true, includes/excludes/useTransitiveFiltering will apply to transitive dependency artifacts in addition to the main project dependency artifacts. If false, useTransitiveFiltering is meaningless, and includes/excludes only affect the immediate dependencies of the project. By default, this value is true. (Since 2.2)
Default value is: true.
useTransitiveFiltering boolean Determines whether the include/exclude patterns in this dependency set will be applied to the transitive path of a given artifact. If true, and the current artifact is a transitive dependency brought in by another artifact which matches an inclusion or exclusion pattern, then the current artifact has the same inclusion/exclusion logic applied to it as well. By default, this value is false, in order to preserve backward compatibility with version 2.1. This means that includes/excludes only apply directly to the current artifact, and not to the transitive set of artifacts which brought it in. (Since 2.2)
Default value is: false.

unpackOptions

Specifies options for including/excluding/filtering items extracted from an archive. (Since 2.2)

  • "lf" - Use a single line-feed line endings
  • "dos" - Use DOS-style line endings
  • "crlf" - Use Carraige-return, line-feed line endings

Default value is: true.

Element Type Description
source String Sets the absolute or relative path from the module's directory of the file to be included in the assembly.

fileMode String Similar to a UNIX permission, sets the file mode of the files included. THIS IS AN OCTAL VALUE. Format: (User)(Group)(Other) where each component is a sum of Read = 4, Write = 2, and Execute = 1. For example, the value 0644 translates to User read-write, Group and Other read-only.
