maven build execution tree

Are there any way to show all plugins and their goals that will be executed for some command set.

I know maven outputs such information but it is clogged with other output and it is not very convenient to extract that information.

I found the plan-maven-plugin. Maybe you should give it a try (I definitely will, tomorrow).

There's a couple commands that can help here:

mvn help:describe -Dcmd=test-compile

Will show you what plugins are invoked at the phase you specify (in this case test-compile). For example:

anew@Wintermute:example$ mvn help:describe -Dcmd=test-compile | grep test-compile
[INFO] 'test-compile' is a phase corresponding to this plugin:
* test-compile: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile

Also helpful are:

mvn help:effective-pom

Will show you, unsurprisingly the effective pom that maven uses to execute. This can be a good way to poke around if you have a parent pom and aren't sure what exactly happens at a specific phase. This is the best way to see what plugins's goals have been bound to a phase in their <executions/> element.

mvn help:describe -Dplugin=groupId:artifactId:version

Will give you some hints as to what features plugins have:

anew@Wintermute:example$ mvn help:describe -Dplugin=org.apache.maven.plugins:maven-deploy-plugin:2.5
[INFO] Scanning for projects...
[INFO]
