Can you share manifestEntries in Maven?

Question

In my master POM, I have <pluginManagement> where I define configurations for the maven-jar-plugin, maven-war-plugin and maven-ear-plugin. Each of these has

<configuration>
  <archive>
    <manifestEntries>
      <Build-Time>${maven.build.timestamp}</Build-Time>
      <SCM-Revision>${scmRevision}</SCM-Revision>
      <SCM-Branch>${scmBranch}</SCM-Branch>
      <Built-By>${user.name}</Built-By>
    </manifestEntries>
  </archive>
</configuration>

Is there a way to share a group of manifest entries so I don't have to add new items to 3 separate places?

Well, the best you can get, I guess, is have it in some file in your project and pass it as `` configuration parameter to these plugins. — Andrew Logvinov, Dec 07 '12 at 21:21
@AndrewLogvinov Sounds pretty reasonable, why not post an answer? — Duncan Jones, Dec 08 '12 at 08:03

I would do the following:

Create single manifest file with necessary content and property placeholders, and place it into src/main/resources.
Have maven-resources-plugin process this file and generate manifest with actual property values.
Provide jar, war and ear plugins with link to this file.

Here's a sample configuration:

<configuration>
  <archive>
    <manifestFile>${project.build.outputDirectory}/manifest.file</manifestFile>
  </archive>
</configuration>

Does this support each individual jar, war, etc being able to add to the manifest? – Snekse Dec 10 '12 at 16:10
@Snekse Can you rephrase your question? – Andrew Logvinov Dec 10 '12 at 16:23
Would adding a manifestFile element in the POM still allow me to separately customize each archive, such as adding `classpath` entries to the EAR and hand edited URL entries. So basically can I concat manifestEntries + manifestFile into a new manifest.mf? Hope that helps. – Snekse Dec 11 '12 at 15:39
@Snekse No, I don't think that it's possible. – Andrew Logvinov Dec 11 '12 at 15:41
