Detect Fedora 23-25 package pmd jars

[jayvdb]

Fedora package pmd is provided on Fedora 23+, but it only provides the jars, and does not include a pmd script.

As a result coala complains, and recommends installing pmd.

It would be nice if coala found and ran the jars.

Thanks for reporting this issue! A coalaian will look at it soon.

Hm, how are the jars run? Directly? I don't have a fedora around, but this should be simple. Would be willing to help?

[jayvdb]

I am guessing pmd is a simple shell script. If so, paste it here and I'll try to run it, and then figure out the oneliner needed to run it in coala.

Hm it's not a oneliner... http://pastebin.com/iMTGVNgs

Thanks. Found the source here : https://github.com/pmd/pmd/blob/master/pmd-dist/src/main/scripts/run.sh

I've raised the bug upstream, so hopefully this will "just work" in the future:
https://bugzilla.redhat.com/show_bug.cgi?id=1374887

It is a bit of a pain to build pmd manually, as toolchains.xml needs to be created manually on Fedora, and then maven wants jdk 1.7, but Fedora provides jdk 1.8 only.
I worked around this by using dnf copr enable jschwart/openjdk-7 .
It is likely that pmd works on jdk 8, since Fedora pmd package is using a jdk and only jdk 8 is available.

Closed wontfix, as component pmd has been retired in Fedora 26, and the last RPM is pmd-5.5.0-2.fc25.src.rpm.
