Java hand-over (was: State of maven build system, gradle and Apache comm

Hello,

as stated earlier in this thread. I'm not going to spend any more time on packaging java. But for others, more skilled in this mine-field, being able to continue the work, here are some notes. Even if non of this is working it at least saves some time figuring out the source-urls and checksums :-)

So here are my scratches from my work on packaging some java packages and maven. Good Luck!

Notes for a "junits" ant task: outputting the reports into some "${build.home}/test-reports" seems to be a good idea.

;    <target name="junit" depends="compile-test">
;            <test name="${test.entry}" todir="${build.home}/test-reports" if="test.entry"/>
;            <batchtest fork="yes" todir="${build.home}/test-reports" unless="test.entry">
;                <fileset dir="${test.home}">
;                    <include name="**/*Test.java"/>
;                    <exclude name="**/*AbstractTest.java"/>
;                </fileset>
;            </batchtest>
;            <batchtest>
;                <fileset dir="src/test" includes="**/*Test.java"/>
;            </batchtest>
;    <target name="compile-test" depends="compile" description="Compile tests">
;        <compile module="test" refid="path.run"/>
;    </target>

Helper scripts for building Maven components with ant

This is a package from Debian. It adds some environment that should simplify
generating of (originally) Debian packages. I seems to be meant to use maven
and implement something like the "default build.xml" we have for
ant-build-system. I doubt this is the way to go since it does thing guix
typically does in guile. Additionally it is designed to be felxible which
makes it more complicated again.

It includes a "modello" implementation, which *may* be worth carving out -
some person knowledable in java may be able to tell if it.

This should become the main maven package.

Maven requires *a lot* of other jar-files, see list below. 'Bootstrapping'
this package (as the documentation calls it) required some .jar files to
exist. Some of which are included, others are downloaded from the internet.

The source is organized into some sub-projects, e.g 'maven-artifacts', some of
which I ewas able to build - see the package descriptions below. Using
separate packages for each of these sub-projects will propably not be
senceful, I just did it to figure out how far I can get.

subprojects: artifact, builder-support, compat, core, embedder, model,
             model-builder, plugin-api repositoy-metadata, settings,
             settings-builder

One solution could be to process each of the 'configure', 'build', 'install'
steps of the ant-builder for each subproject.

maven-core requires: Subprojects: maven-artifact, maven-execution,
    maven-model, maven-graph maven-internal maven-lifecycle maven-plugin
    maven-project maven-repository maven-session
