We are using Jenkins maven plugin for building and deploying war applications. In the jenkinsfile we have the command (I removed the list of profiles for the sake of simplicity):
mvn release:clean release:prepare -P<profiles> -U -DautoVersionSubmodules="true" -Darguments="-T 1C -DskipTests=true" -V --batch-mode --errors
The built war artifact has MANIFEST.MF file with field Release-Name set to main.
Release-Name: main
In the parent pom.xml there are some extra settings for customize MANIFEST.MF but it seems to me that "Release-Name" is added by default because it is not listed below:
<manifestEntries>
<Version>${project.version}</Version>
<Revision-Number>${buildNumber}</Revision-Number>
<Branch>${GIT_BRANCH}</Branch>
<Local-Branch>${scmBranch}</Local-Branch>
</manifestEntries>
So I tried to look into the maven release plugin source code from this repository but I couldn't find anything helpful. Then the main question is how the field "Release-Name" is filled because I'd like to change it into some more meaningful value.
