Re: MANIFEST.MF in .jar created by Maven? / project.properties

[Alex Vollmer]

I ran into this problem too. You can either hack the 'maven-jar' plugin 
or you can do what I did (which is terribly hacky) and make a 'postGoal' 
that un-jars the jar you just made and re-build it with a fresh manifest 
like so:

<?xml version="1.0"?>
<project xmlns:j="jelly:core"
   xmlns:maven="jelly:maven"
   xmlns:ant="jelly:ant">
   <!--
   This post-goal hook was put in to replace the standard 
META-INF/MANIFEST.MF file
   that Maven generates. For some deep, dark, hidden reason the extra 
information put
   in that file, for this component, causes the PaymentException class 
to not be loaded
   by the class-loader. So we replace the noisy MANIFEST.MF file with a 
very plain one.
   -->
   <postGoal name="jar:jar">
       <ant:mkdir dir="${maven.build.dir}/temp-jar"/>
       <ant:unjar src="${maven.build.dir}/${maven.final.name}.jar"
           dest="${maven.build.dir}/temp-jar"/>
       <ant:delete dir="${maven.build.dir}/temp-jar/META-INF" 
quiet="true"/>
       <ant:jar destfile="${maven.build.dir}/${maven.final.name}.jar"
           basedir="${maven.build.dir}/temp-jar"
           excludes="META-INF">
           <ant:manifest>
               <ant:attribute name="Built-By" value="${user.name}"/>
           </ant:manifest>
       </ant:jar>
       <ant:delete dir="${maven.build.dir}/temp-jar"/>
   </postGoal>
</project>

Gruesome isn't it? ;-)

Hello.

Is there a way to change the properties in MANIFEST.MF that Maven 
generates when creating a .jar of the project?

Also, is there any documentation on all the properties that can be set 
in project.properties?

Thank you.
