> This bug is similar to http://jira.codehaus.org/browse/MANTRUN-57;jsessionid=awtyLFBPEQN6vVmwu4 - the difference being the plugins are not correctly merged.
> In the parent's POM, the following was defined:
> <build>
> <pluginManagement>
> <plugins>
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-eclipse-plugin</artifactId>
> <configuration>
> <downloadSources>true</downloadSources>
> <additionalBuildcommands>
> <buildcommand>
> parentBuildCommand
> </buildcommand>
> </additionalBuildcommands>
> </configuration>
> </plugin>
> </plugins>
> </pluginManagement>
> </build>
> in the child's POM, the following was defined.
> <build>
> <pluginManagement>
> <plugins>
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-eclipse-plugin</artifactId>
> <configuration>
> <additionalBuildcommands>
> <buildcommand>
> childBuildCommand
> </buildcommand>
> </additionalBuildcommands>
> </configuration>
> </plugin>
> </plugins>
> </pluginManagement>
> </build>
> I expect the effective POM to look like this:
> <build>
> <pluginManagement>
> <plugins>
> <plugin>
> <artifactId>maven-eclipse-plugin</artifactId>
> <configuration>
> <additionalBuildcommands>
> <buildcommand>
> parentBuildCommand
> </buildcommand>
> <buildcommand>
> childBuildCommand
> </buildcommand>
> </additionalBuildcommands>
> <downloadSources>true</downloadSources>
> </configuration>
> </plugin>
> </plugins>
> </pluginManagement>
> </build>
> Outside of the common problem of the <plugin> element being duplicated, here's the issue this bug is trying to address:
> In the effective pom, the the <downloadSources> element was correctly merged, however, the <buildCommand> element was not. It seems like the merging only correctly happens down to a given level.
> I noticed that http://jira.codehaus.org/browse/MNG-2297;jsessionid=awtyLFBPEQN6vVmwu4 has a patch attached, so this may be fixed in 2.0.5, I just wanted to raise the use case in case that patch did not address this specific problem.
> I'm attaching the POMs needed to reproduce the problem and the effective POM for the child.
