--------------------------------
Fix Version: 2.0.5
> Inherited plugin executed twice if child pom merges configuration
> -----------------------------------------------------------------
>
> Key: MNG-2237
> URL: http://jira.codehaus.org/browse/MNG-2237
> Project: Maven 2
> Type: Bug
> Components: Inheritence and Interpolation
> Versions: 2.0.4
> Reporter: Joerg Schaible
> Fix For: 2.0.5
>
>
> According the docs the configuration of a plugin is merged, when the plugin
> is inherited. This actually hapens, but the plugin with the merged
> configuration is added twice in the effective-pom and therefore executed
> twice.
> Setup a parent pom with a plugin configuration to attach the javadocs:
> {noformat}
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-javadoc-plugin</artifactId>
> <executions>
> <execution>
> <id>attach-javadocs</id>
> <goals>
> <goal>jar</goal>
> </goals>
> </execution>
> </executions>
> <inherited>true</inherited>
> <configuration>
> <linksource>true</linksource>
> </configuration>
> </plugin>
> {noformat}
> and a child pom that adds additional elements in the configuration:
> {noformat}
> <plugin>
> <artifactId>maven-javadoc-plugin</artifactId>
> <configuration>
> <links>
> <link>http://java.sun.com/j2se/1.4.2/docs/api/</link>
>
> <link>http://jakarta.apache.org/commons/logging/commons-logging-1.0.4/docs/apidocs/</link>
> <link>http://jmock.codehaus.org/docs/javadoc/</link>
> <link>http://www.junit.org/junit/javadoc/3.8.1/</link>
> </links>
> </configuration>
> </plugin>
> {noformat}
> In this case the javadoc is generated twice, the goal help:effective-pom
> reveals, that the plugin was merged, but added twice.
