Manifest Entries

 If you find that the other configuration options for Maven Archiver are not
 enough for manipulating the manifest, you can add your own entries to it.
 This is done with the <<<\<manifestEntries\>>>> configuration element.
 
 In this example we'll add some entries to the manifest by specifying what we'd
 like in the <<<\<configuration\>>>>/<<<\<archive\>>>> element of
 maven-jar-plugin.

 <<Note:>> As with all the examples here, this configuration can be used in all
 plugins that use Maven Archiver, not just maven-jar-plugin as in this example. 

+-----+
<project>
  <url>http://some.url.org/</url>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        ...
        <configuration>
          <archive>
            <manifestEntries>
              <mode>development</mode>
              <url>${project.url}</url>
            </manifestEntries>
          </archive>
        </configuration>
        ...
      </plugin>
    </plugins>
  </build>
  ...
</project>
+-----+

 As you see above you can use literal values or you can have values from the
 POM interpolated into literals or simply use straight POM expressions. So this
 is what your resultant manifest will look like inside the generated jar:

+-----+
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven ${maven.version}
Built-By: ${user.name}
Build-Jdk: ${java.version}
mode: development
url: http://some.url.org/
+-----+

 <<Note:>> If your pom.xml does not have the <<<\<url\>>>> element, referenced
 through interpolation, then the entry <<<url>>> will <<not>> be in the
 manifest.
