[fedora-java] Installing effective Maven POM files

[Mikolaj Izdebski]

Status report.

> 5. I will implement the described behaviour before the next Java SIG
>    meeting and make it available in rawhide.

Everything is implemented as I promised. Respective packages are built
for rawhide, but not tagged yet. I expect interested parties to test
the new behaviour before I tag the builds. I will tag them if there
are no objections.

> 1. %mvn_install will install raw POMs into /usr/share/maven-poms
>    as this was always done
> 
> 2. %mvn_install will additionally install effective POMs into some
>    other location (perhaps /usr/share/maven-fragments) for every
>    non-POM artifact

> 3. XMvn and all scripts and programs that use is (including xmvn,

Done: http://git.fedorahosted.org/cgit/javapackages.git/commit/?id=025470e7b5967d5edff77d85371e6d385dec1a99

With option -Dmaven.local.effective.pom=false mvn-rpmbuild and mvn-local
will not resolve effective POMs, ever. Respective option for %mvn_build
is -E or --disable-effective-poms.


I tested the new behaviour and it seems to be as expected.

1. Rebuild some package that is using %mvn_build (for example apache-commons-io)

2. Install the package.

3. Verify that both raw POM and effective POM are installed:
  $ rpm -ql apache-commons-io | grep pom
  /usr/share/maven-effective-poms/JPP-commons-io.pom
  /usr/share/maven-poms/JPP-commons-io.pom

4. Verify that POM in /usr/share/maven-poms is raw:
  $ grep parent /usr/share/maven-poms/JPP-commons-io.pom
    <parent>
      <artifactId>commons-parent</artifactId>
    </parent>

5. Verify that POM in /usr/share/maven-effective-poms is effective:
  $ grep parent /usr/share/maven-effective-poms/JPP-commons-io.pom

6. Rebuild some package and verify that effective POM is resolved by default:

%mvn_build
