-Maven - seen on both 3.3.9 and 3.5.0
JDK - Openjdk 1.7.0.141, oracle 1.7.0_75, oracle 1.7.0_67
Yes, we are doing a maven job in jenkins
Running test with 2.6 now ( will also run test with those overrides, wasn't
sure if I could override plugins like that)
228M
Which flags would you like?

Ugh, I apologize, I thought I had narrowed it down to my two modules (i.e.
docbook + assembly) but turns out I had screwed up something context switching.
It is slow, but it is under certain conditions that are not the ones laid out
above, as well as those versions above.
I can state for certain I've seen it occuring on

I'm slowly going through iterations so I don't screw up my analysis again

> poor performance of jar-with-dependencies when run in same run as docbook

> Key: MASSEMBLY-866
> URL: https://issues.apache.org/jira/browse/MASSEMBLY-866
> Project: Maven Assembly Plugin
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: John Vines
> Labels: performance
>
> I apologize for the lack of information, but we have a large build
> environment which I cannot share, but I'll try to explain things as best I
> can.
> In our full build path, we have 2 components that I've found have side
> effects. One is a doc build which uses the docbkx-maven-plugin
> (https://github.com/mimil/docbkx-tools) to generate documentation (and
> usually takes a while, ~27 minutes) and another which builds a
> jar-with-depends for our UI. Prior to upgrade the assembly plugin to 3.0.0
> from 2.3 or 2.5 (I cannot recall) everything ran fine. After upgrading we
> found our jenkins builds taking about 40 more minutes, most of this change
> was in maven-assembly-plugin for that UI jar-with-dependencies
> {code}assembly-plugin:3.0.0:single (make-assembly) @ sqrrl-web-dist-ui ---
> 16:17:37 [INFO] Reading assembly descriptor: src/main/assembly/dist-ui.xml
> 16:17:40 [INFO] Building jar:
> /var/lib/jenkins/workspace/sqrrl-master-build/web/dist-ui/target/sqrrl-web-dist-ui-2.8.0-SNAPSHOT-jar-with-dependencies.jar
> 17:01:54 [INFO] {code}
> Eventually I isolated to a case where just that doc and that jar-with-deps
> being built would cause the jar-with-deps to take ~40 minutes, but if I built
> it by itself (all other maven options being equal) it would take about 1.5
> minutes.
> I'm honestly not too familiar with the inner workings of this plugin, nor the
> maven docbook plugin, but my hunch was that the docbook plugin was
> 'corrupting' or otherwise altering the main maven jvm in such a way to cause
> this. It does use some really old plexus plugins, among others, afterall.
> However, I stumbled across MASSEMBLY-424 and tested forking
> maven-assembly-plugin:3.0.0 and updating plexus-archiver to 3.5, plexus-io to
> 3.0.0 and plexus-utils to 3.1.0 and ran my 2 module build with the custom
> plugin and it ran just as quick as being run standalone (1.5minutes). (To
> build it with those plugins I had to disable checkstyle and enforcer though
> since at least one of those plugins versions was java7)
> One last datapoint is that in our jar-with-deps we are including
> bouncycastle's bcpix and bcprov and explicitly excluding them from the
> jar-with-depends also made that 2 module build faster (but not as fast), so
> I'm not 100% sure it's the docbook plugin was the catalyst there.
