Apache Maven Archiver

The Maven Archiver is mainly used by plugins to handle packaging. The version numbers referenced in the Since column on this page are the version of the Maven Archiver component - not for any specific plugin. To see which version of Maven Archiver a plugin uses, go to the site for that plugin.

archive

Element	Description	Type	Since
addMavenDescriptor	Whether the created archive will contain these two Maven files: The pom file, located in the archive in `META-INF/maven/${groupId}/${artifactId}/pom.xml` A pom.properties file, located in the archive in `META-INF/maven/${groupId}/${artifactId}/pom.properties` The default value is `true`.	boolean
compress	Activate compression for the archive. The default value is `true`.	boolean
forced	Whether recreating the archive is forced (default) or not. Setting this option to `false`, means that the archiver should compare the timestamps of included files with the timestamp of the target archive and rebuild the archive, only if the latter timestamp precedes the former timestamps. Checking for timestamps will typically offer a performance gain (in particular, if the following steps in a build can be suppressed, if an archive isn't recrated) on the cost that you get inaccurate results from time to time. In particular, removal of source files won't be detected. An archiver doesn't necessarily support checks for uptodate. If so, setting this option to `true` will simply be ignored. The default value is `true`.	boolean	2.2
index	Whether the created archive will contain an `INDEX.LIST` file. The default value is `false`.	boolean
manifest
manifestEntries	A list of key/value pairs to add to the manifest.	Map
manifestFile	With this you can supply your own manifest file.	File
manifestSections
pomPropertiesFile	Use this to override the auto created pom.properties file (only if `addMavenDescriptor` is set to `true`)	File	2.3

manifest

Element	Description	Type	Since
addClasspath	Whether to create a `Class-Path` manifest entry. The default value is `false`.	boolean
addDefaultEntries	If the manifest will contain these entries: Created-By: Maven Archiver ${maven-archiver.version} Build-Jdk-Spec: ${java.specification.version} The default value is `true`.	boolean	3.4.0
addDefaultImplementationEntries	If the manifest will contain these entries: Implementation-Title: ${project.name} Implementation-Version: ${project.version} Implementation-Vendor: ${project.organization.name} The default value is `false`.	boolean	2.1 and 2.6
addDefaultSpecificationEntries	If the manifest will contain these entries: Specification-Title: ${project.name} Specification-Version: ${project.artifact.selectedVersion.majorVersion}.${project.artifact.selectedVersion.minorVersion} Specification-Vendor: ${project.organization.name} The default value is `false`.	boolean	2.1
addBuildEnvironmentEntries	If the manifest will contain these entries: Build-Tool: ${maven.build.version} Build-Jdk: ${java.version} (${java.vendor}) Build-Os: ${os.name} (${os.version}; (${os.arch}) The default value is `false`.	boolean	3.4.0
addExtensions	Whether to create an `Extension-List` manifest entry. The default value is `false`.	boolean
classpathLayoutType	The type of layout to use when formatting entries in the created `Class-Path`. Valid values are: `simple`, `repository` (the same as a Maven classpath layout) and `custom`. Note: If you specify a type of `custom` you must also set `customClasspathLayout`. The default value is `simple`.	String	2.4
classpathPrefix	A text that will be prefixed to all your `Class-Path` entries. The default value is `""`.	String
customClasspathLayout	The layout expression to use when the layout type set in `classpathLayoutType` has the value `custom`. Expressions will be evaluated against the following ordered list of classpath-related objects: The current Artifact instance, if one exists. The current ArtifactHandler instance from the artifact above. Note: If you specify a layout type of `custom` you must set this layout expression.	String	2.4
mainClass	The `Main-Class` manifest entry.	String
packageName	Package manifest entry.	String
useUniqueVersions	Whether to use unique timestamp Snapshot versions rather than -SNAPSHOT versions. The default value is `true`.	boolean	2.4

manifestSection

Element	Description	Type	Since
name	The name of the section.	String
manifestEntries	A list of key/value pairs to add to the manifest.	Map
