get rid of POM not found warning for org.eclipse.m2e:lifecycle-mapping


With intent to get m2e 1.0 working correctly I have had to specify the lifecycle mapping:

    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>org.bsc.maven</groupId>
                                    <artifactId>maven-processor-plugin</artifactId>
                                    <versionRange>[2.0.2,)</versionRange>
                                    <goals>
                                        <goal>process</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <execute />
                                </action>
                            </pluginExecution>
                        </pluginExecutions>                         
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>

But then I get this warning:

 [WARNING] The POM for org.eclipse.m2e:lifecycle-mapping:jar:1.0.0 is missing, no dependency information available
 [WARNING] Failed to retrieve plugin descriptor for org.eclipse.m2e:lifecycle-mapping:1.0.0: Plugin org.eclipse.m2e:lifecycle-mapping:1.0.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.eclipse.m2e:lifecycle-mapping:jar:1.0.0

if I run some specific maven task for example mvn clean install findbugs:findbugs (If I run only mvn clean install then there is no such message)

I know that the problem is that this POM does not exists, because it is only defined to hold the mapping information. (m2e lifecycle-mapping not found)

Anyway, I want to keep my build clean, without any warnings, so how can I get rid of this specific one? (My CI server checks that there is no warning.)

I use Maven 3.0.2 and tried Maven 3.0.3 too, but the same result.


Solution

  • My team works around this problem by wrapping the relevant configuration in a profile:

    <profile>
      <id>only-eclipse</id>
      <activation>
        <property>
          <name>m2e.version</name>
        </property>
      </activation>
      <build>
        <pluginManagement>
          <plugins>
            <plugin>
              <groupId>org.eclipse.m2e</groupId>
              <artifactId>lifecycle-mapping</artifactId>
              <version>1.0.0</version>
              <configuration>
                ...
              </configuration>
            </plugin>
          </plugins>
        </pluginManagement>
      </build>
    </profile>
