Maven Execution Plan

Question

I have a long build with many steps, plugins, and executions configured for about 30 poms belonging to a complex modular project. Since the assembly takes too much (2 hours), I would simplify it a bit, for which I would like maven to list me all the steps that he completed without completing it. Something like:

$ mvn --dry-run clean [INFO] Reactor Build Order: [INFO] [INFO] Main project [INFO] Module#1 [INFO] Module#2 [..] [INFO] [INFO] ------------------------------------------------------------------------ [INFO] Building Main Project [INFO] ------------------------------------------------------------------------ [INFO] [INFO] --- maven-clean-plugin:2.4.1:clean (default-clean) @ main --- [INFO] [INFO] [INFO] ------------------------------------------------------------------------ [INFO] Building Module#1 [INFO] ------------------------------------------------------------------------ [INFO] [INFO] --- maven-clean-plugin:2.4.1:clean (default-clean) @ module1 --- [INFO] [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 0:01.020s [INFO] Finished at: Thu Apr 26 09:56:14 CEST 2012 [INFO] Final Memory: 198M/379M [INFO] ------------------------------------------------------------------------ 

Is there any way to get this information if I don’t dig into a few megabytes of the log file?

Answer 1

Since there seems to be no OOTB way, I ended up writing plan-maven-plugin . It allows you to deploy a plan with the goals parameter:

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

or execute it as part of a normal assembly:

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

Output Example:
