Re: [m2e-users] Can't get simple lifecycleMapping to work in plugin
All you need to do is include the extension point as follows:

    <extension
         point="org.eclipse.m2e.core.lifecycleMappingMetadataSource">
    </extension>

And make sure you have your lifecycle-mapping-metadata.xml file in the root of your contributing plugin. (Don't forget to add it to the build.properties file as well so it gets included).

I'm using m2e 1.0 and I'm running into a small problem (or, more likely, lack of understanding on my part) with some lifecycleMapping configuration. Here is the situation:

We have a custom maven packaging type (tomcat-deployable). When a project with that packaging type is imported into Eclipse, we want the resources:resources goal to be run on it (and nothing else - it isn't a Java project). I got it working by adding the following to the POM:

<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<versionRange>[2.0.0,]</versionRange>
<goals>
<goal>resources</goal>
</goals>
</pluginExecutionFilter>
<action>
<execute />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>

This works fine for one project, but I want to make a plugin to handle this so that every project we have doesn't have to do this. So, in one of our plugins, I added the following:

In lifecycle-mapping-metadata.xml:

<lifecycleMappingMetadata>
<lifecycleMappings>
<lifecycleMapping>
<packagingType>tomcat-deployable</packagingType>
<lifecycleMappingId>org.lds.stack.ide.tomcatDeployableLifecycleMapping</lifecycleMappingId>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<versionRange>[2.0.0,)</versionRange>
<goals>
<goal>resources</goal>
</goals>
</pluginExecutionFilter>
<action>
<execute />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMapping>
</lifecycleMappings>
</lifecycleMappingMetadata>

In the corresponding plugin.xml:

<extension point="org.eclipse.m2e.core.lifecycleMappingMetadataSource" />
<extension point="org.eclipse.m2e.core.lifecycleMappings">
   <lifecycleMapping
         class="org.lds.stack.ide.TomcatDeployableLifecycleMapping"
         id="org.lds.stack.ide.tomcatDeployableLifecycleMapping"
         name="Tomcat Deployable Lifecycle Mapping" />
</extension>

This doesn't cause the resources goal to be run, however. I do see the following in the Eclipse logs:

So, it appears to be picking up my lifecycle mapping, but nothing actually happens as far as I can tell.

Any ideas as to what I'm missing?

Thanks,
