Problem with execution of eclipse mojo on packaging type ear

[Kürpig, Jürgen <ku...@adesso.de>]

Hi all,

I'm using the maven-eclipse-plugin to create the project meta files like .project or .classpath for eclipse. Basically, the intention of the maven-eclipse-plugin was not to use the default dependency resolution, instead the maven-eclipse-plugin uses its own dependency resolution. Especially in a multi module project the dependency resolution for sub modules (often available only in source) shouldn't force an error on source module not build yet. However, works fine until the packaging is type "ear". 

The reason seems to be the phase binding of the eclipse-mojo, see annotations in source code of the plugin:
...
* @goal eclipse
* @execute phase="generate-resources"
...
In case of packaging type "ear" maven detects the maven-ear-plugin is required because bound to the default build life cycle too. Seems to be that Maven executes the demanded default dependency resolution by maven-ear-plugin, see again the related annotations in source code of the maven-ear-plugin:
...
* @requiresDependencyResolution test
...
However, the maven-ear-plugin interferes the eclipse plugin before its own execution. Of course the maven-ear-plugin detects the missing artifacts for all the (source) sub module not build yet and the execution fails.

Is there any chance to solve this with any plugin configuration or is there any other way to solve this issue? My first idea was to "unbind" the maven-eclipse-plugin from the default life cycle, but how can I reach this goal? 
Anyway, if the default life cycle cannot be overridden, it would be nice to omit the default phase binding for maven-eclipse-plugin in future releases and define it explicity in plugin configuration if really needed.

Cheers,
Juergen
