maven-ear-plugin - How to manipulate Manifest.MF of webModule and ejbModule? - maven

Question

I have a multimodule maven project with the following structure:
app (parent)
-- pom.xml
-- app-ear
-- pom.xml
-- app-ejb
-- src
-- pom.xml
-- app-web
-- src
-- pom.xml
app/pom.xml
This is my app/pom.xml (parent project) where I put all my application dependencies:

My problem is that app.ear/app-web.war!META-INF/MANIFEST.MF and app.ear/app-ejb.jar!META-INF/MANIFEST.MF looks like this:
Manifest-Version: 1.0
Build-Jdk: 1.6.0_24
Class-Path: lib/javax.faces-2.0.9.jar lib/richfaces-core-api-4.2.0.Fin
al.jar lib/richfaces-core-impl-4.2.0.Final.jar lib/richfaces-componen
ts-api-4.2.0.Final.jar lib/richfaces-components-ui-4.2.0.Final.jar li
b/cssparser-0.9.5.jar lib/sac-1.3.jar lib/guava-10.0.1.jar lib/jsr305
-1.3.9.jar
Created-By: Apache Maven
Archiver-Version: Plexus Archiver
And I really have to remove the Class-Path entry from these MANIFEST.
Why? Because it seems that RichFaces is being loaded two times in classpath of my application. (One from app.ear/lib folder and another from app.ear/app-web.war!META-INF/MANIFEST.MF Class-Path entry). And when I try to deploy app.ear in my Application Server (Oracle Weblogic 10.3.5) I get some errors like that:
INFO: Unsanitized stacktrace from failed start...
java.lang.IllegalArgumentException: duplicate key: class javax.faces.validator.RequiredValidator
at com.google.common.base.Preconditions.checkArgument(Preconditions.java:115)
at com.google.common.collect.RegularImmutableMap.<init>(RegularImmutableMap.java:72)
at com.google.common.collect.ImmutableMap$Builder.fromEntryList(ImmutableMap.java:221)
at com.google.common.collect.ImmutableMap$Builder.build(ImmutableMap.java:207)

at org.richfaces.application.ValidatorModule.configure(ValidatorModule.java:60)
at org.richfaces.application.ServicesFactoryImpl.init(ServicesFactoryImpl.java:27)
It's weird that if I run mvn package in my app-web project, the Class-path entry does not go to app-web.war/META-INF/MANIFEST.MF. It only occurs when I run mvn package in my app parent project.
So, how could I remove the Class-path entry of webModule and ejbModule MANIFEST file?
I found a similar problem in this thread but without a solution.
I appreciate any help.
Thanks,
Mauricio

Answer 1

You need to add the following entry in your app-ear/pom.xml inside the configuration tag
<archive>
<manifest>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
</manifest>
<manifestEntries>
<Created-On>${build.timestamp}</Created-On>
<Ant-Version>${ant.version}</Ant-Version>
<Java-Version>${ant.java.version}</Java-Version>
</manifestEntries>
</archive>
In general the addDefaultImplementationEntries tag that is set to false prevents all default entries (like the one you want) to be written in the manifest. afterwards you can add whatever you want to include. I added some samples fo that you can see.
