  • 0

I have a long build with numerous steps, plugins and executions configured in roughly 30 poms belonging to a complex modularized project. As the build is taking too much (2h) I’d like to streamline it a bit, for which I’d like maven to list me all the steps it would go through without executing it. Something like:

$ mvn --dry-run clean

[INFO] Finished at: Thu Apr 26 09:56:14 CEST 2012
[INFO] Final Memory: 198M/379M
[INFO] ------------------------------------------------------------------------

Is there any way to have such information without me digging in a couple of megs of a log file?

    As there’s apparently no OOTB way to do it, I ended up writing the plan-maven-plugin. It allows you to unroll the plan providing the goals parameter:

    mvn plan:plan -Dgoals=clean,javadoc:jar,sources:jar,package,gpg:sign,install

    or to execute it as part of the normal build:

    mvn plan:plan clean javadoc:jar sources:jar package gpg:sign install

    Sample output:

    $ mvn plan:plan clean javadoc:javadoc package install site:site
