maven 3 - How to skip building of the pom in multi-module project -


i'm trying optimize build process (in development) in term of time build whole tree of maven multi-module project. of pom aggregation of sources/libraries rarelly (and typically) never change. specific sub-questions are

  1. is possible somehow configure maven not build pom if there no changes in sources specified in pom:project/build/sourcedirectory attribute?

  2. or possible (at least) conditionally disable maven-bundle-plugin? - takes of time.

google not find relevant q#1. typical solution not work #2 - when try specify 'executions' maven-bundle-plugin (like this)

<plugin>     <groupid>org.apache.felix</groupid>     <artifactid>maven-bundle-plugin</artifactid>     <version>${maven-bundle-plugin.version}</version>     <extensions>true</extensions>     <executions>         <execution>             <id>osgi-bundle</id>             <phase>bundle</phase>             <goals>                 <goal>bundle</goal>             </goals>

i receive error in output

[bundle:bundle] bundle artifact-id:bundle-id:bundle:0.1.0-snapshot : jar empty: dot error(s) found in bundle configuration

any appreciated. i'm aware following:
* disable maven plugin defined in parent pom (maven-bundle-plugin can't work 'executions' tag)
* skip execution of maven plugin if file not exist (maven-bundle-plugin not have skip confiuration option)
* how skip lifecycle phase in multi maven module (the same previous)
* if entire maven-bundle-plugin moved profile, maven not recognize packaging=bundle.

finally have admit (c) eugene kuleshov - "maven don't track sources/changes, full build."

but, returning java after 5+ on .net , 5+ years erlier on c++, looks weird me such common feature incremental build not support used tool having history of 10+ years. not spend time on waiting rebuild each , every unchanged module in multi-module project , decided make customized version of maven 3.0.4 :)

feel free grab here http://code.google.com/p/maven-onchange-activator/, try , report issues.
