[m2e-dev] Generated Resources not picked during first build.

[CoderPlus Team <admin@xxxxxxxxxxxxx>]

Hi,

I'm struggling to make an m2e-connector work as expected with m2e.

The maven-remote-resources-plugin dynamically adds generated source folders to the maven project using

project.getResources().add( resource );

or

project.getTestResources().add( resource );

as seen at https://github.com/apache/maven-plugins/blob/trunk/maven-remote-resources-plugin/src/main/java/org/apache/maven/plugin/resources/remote/ProcessRemoteResourcesMojo.java#L535

I had written a very simple connector which manages the plugin's lifecycle. 

<plugin>

<!-- this plugin copies all shared resources -->

<artifactId>maven-remote-resources-plugin</artifactId>

<executions>

<execution>

<id>attach-shared-resources</id>

<goals>

<goal>process</goal>

</goals>

<phase>generate-resources</phase>

<configuration>

<resourceBundles>

<resourceBundle>${project.groupId}:shared-resources:${project.version}</resourceBundle>

</resourceBundles>

<attached>true</attached>

<attachToMain>true</attachToMain>

<outputDirectory>${project.build.directory}/shared-resources</outputDirectory>

</configuration>

</execution>

</executions>

</plugin>

If I import a project with this configuration, the connector invokes the plugin as expected and it unpacks the shared resources to target/shared-resources. This all works good. But the resource directory attached by the maven-plugin(in this case target/shared-resources) is not automatically  copied to the target/classes directory by the maven-resources-plugin  during the process-resources phase(It copies other resources but not the dynamically attached ones). If I do a manual build after importing the project, it processes the generated resources and copies it to target/classes. 

I'm struggling to find why this doesn't work the first time(when the project is imported)

This is  the link to the build participant - 

https://github.com/coderplus/m2e-connector-for-maven-remote-resources-plugin/blob/master/core/src/com/coderplus/m2e/remoteresourcescore/CoderPlusBuildParticipant.java#L84

Is there something wrong with the BuildParticipant. I had also tried attaching the outputDirectory from within the BuildParticipant, but that didn't help.

Similar functionality works correctly when we use the build-helper-maven-plugin's add-resource goal

Thanks,

Aneesh
