[m2e-users] Re : m2eclipse 1.0 : NullPointerException when lifecycle-map

[Adrian Gonzalez <adr_gonzalez@xxxxxxxx>]

Hello,

I just want to pin lifecycle version in parent pom to 1.0.0.

Something like 

<pluginManagement>
  <plugins>
   <plugin>
     <groupId>org.eclipse.m2e</groupId>
     <artifactId>lifecycle-mapping</artifactId>

     <version>1.0.0</version>

   </plugin>

  </plugin>

</pluginManagement>

Afterwards, I want to put the following declaration in child pom (without version number) - and this is where I get my NPE :

<pluginManagement>

  <plugins>

    <plugin>

    <groupId>org.eclipse.m2e</groupId>

    <artifactId>lifecycle-mapping</artifactId>

    <configuration>

      <lifecycleMappingMetadata>

        <pluginExecutions>

          <pluginExecution>

            <pluginExecutionFilter>

              <groupId>org.apache.maven.plugins</groupId>

              <artifactId>maven-dependency-plugin</artifactId>

              <versionRange>[2.0,)</versionRange>

              <goals>

                <goal>unpack</goal>

              </goals>

              </pluginExecutionFilter>

              <action>

                <ignore />

              </action>

            </pluginExecution>

          </pluginExecutions>

        </lifecycleMappingMetadata>

      </configuration>

    </plugin>

  </plugins>

</pluginManagement>

I am not following. Why does version=1.0.0 forbid specifying lifecycle
mapping in parent pom?
