Jar Settings

PropertyOptional?Description
maven.jar.final.name Yes Name of the generated JAR file. Defaults to ${maven.final.name}.jar.
maven.jar.excludes Yes Specifies a list of patterns to exclude from the jar process. The default value is **/package.html, and is used by the jar:jar goal.
maven.jar.includes Yes Specifies a list of patterns to include with the jar process. The default value is null.
maven.jar.index Yes Whether to create an index list to speed up classloading. This is a JDK 1.3+ specific feature. Defaults to false.
maven.jar.manifest Yes Specifies the manifest to be used in the creation of a jar. This file is 'merged' with the default manifest created by Maven. Any values specified in the file referenced by this property will override Maven's defaults.
maven.jar.manifest.classpath.add Yes Tells Maven to add classpath information to the jar manifest. This can cause some applications to break, so it has been disabled by default. Set to true to enable classpath information. Only the dependency jars that have the property jar.manifest.classpath set to true will be added to the classpath information.
maven.jar.manifest.extensions.add Yes Tells Maven to add extension information to the jar manifest. This can cause some applications to break, so it has been disabled by default. An Implementation-Vendor-Id attribute will be added for each dependency that has a <vendorId> element set in its <properties> section. Set to true to enable extension information.
maven.jar.mainclass Yes Specifies the Main-Class attribute for your manifest. If not set, no Main-Class attribute will be added to the manifest.
maven.jar.compress Yes Not only store data but also compress them, defaults to true.
maven.jar.manifest.attributes.list Yes Used by the jar:jar goal to define additional attributes to add to the manifest in addition to the other entries already added. Sample: 
maven.jar.manifest.attributes.list = Foo-Attribute,Bar-Attribute
maven.jar.manifest.attribute.Foo-Attribute = I like bread and butter
maven.jar.manifest.attribute.Bar-Attribute = I like toast and jam
maven.jar.manifest.groups.list Yes Used by the jar:jar goal to define sections/groups for the manifest. You can use this to seal classes and add custom attributes to particular packages. Sample: 
maven.jar.manifest.groups.list = MyClass,MyPackage
maven.jar.manifest.MyClass.name = /com/mycompany/MyClass.class
maven.jar.manifest.MyClass.attributes.list = Sealed,Custom
maven.jar.manifest.MyClass.attribute.Sealed = true
maven.jar.manifest.MyClass.attribute.Custom = Anything I want

maven.jar.manifest.MyPackage.name = /com/mycompany/special
maven.jar.manifest.MyPackage.attributes.list = Sealed
maven.jar.manifest.MyPackage.attribute.Sealed = true
