Re: MSOURCES-11 When source plugin is used, it should make sure it is invoked during install

[Aa...@Globus.ch]

Hello,

I'm trying to write a patch for MSOURCES-11.

If I have this in my pom.xml:

  <build>
        <plugins>
                <plugin>
                        <inherited>true</inherited>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-jar-plugin</artifactId>
                        <version>2.1</version>
                        <executions>
                                <execution>
                                        <goals>
                                                <goal>test-jar</goal>
                                        </goals>
                                </execution>
                        </executions>
                </plugin>
                <plugin>
                        <inherited>true</inherited>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-source-plugin</artifactId>
                        <version>2.0.1</version>
                        <executions>
                                <execution>
                                        <goals>
                                                <goal>jar</goal>
                                        </goals>
                                </execution>
                        </executions>
                </plugin>
        </plugins>
  </build>

the test jar will always be created while the sources-jar will only be 
created if the plugin is configured in the pom.xml of every module. It 
does not work if the plugin is configured in the parent pom!

Somehow, the definition of maven-jar-plugin is passed into module POMs 
while this doesn't happen for maven-source-plugin.

I checked that the config is correct by running mvn help:effective-pom 
which prints:

        <plugin>
          <artifactId>maven-jar-plugin</artifactId>
          <version>2.1</version>
          <executions>
            <execution>
              <goals>
                <goal>test-jar</goal>
              </goals>
            </execution>
          </executions>
          <inherited>true</inherited>
        </plugin>
        <plugin>
          <artifactId>maven-source-plugin</artifactId>
          <version>2.0.1</version>
          <executions>
            <execution>
              <goals>
                <goal>jar</goal>
              </goals>
            </execution>
          </executions>
          <inherited>true</inherited>
        </plugin>

but only the test jar is created. It's as if the config for 
maven-source-plugin is ignored.

When I run maven with -X, there is no trace of the config of 
maven-source-plugin while maven-jar-plugin is mentioned:

[DEBUG] Retrieving parent-POM: org.apache.maven.plugins:maven-plugins::1 
for project: null:maven-resources-plugin:maven-plugin:2.2 from the

org.apache.maven:maven-parent:pom:4 from the repository.
[DEBUG] 
org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.2:runtime 
(selected for runtime)

Does anyone have any idea what the problem could be?
