Unable to locate Source XRef to link to

Question

I have a big maven project that uses the pmd plugin for code quality checks.

since I started using the pmd plugin i get the following warning message:

[WARNING] Unable to locate Source XRef to link to - DISABLED 

I googled and found that i need to implement the jxr plugin.

so I add the following to the build property in the main pom.xml file.

  <plugin>     <groupId>org.apache.maven.plugins</groupId>     <artifactId>maven-jxr-plugin</artifactId>     <version>2.3</version>   </plugin> 

welp it doesn't really change anything.

any ideas what I need to implement in order to resolve this warning message?

output of mvn -version

Apache Maven 3.0.4 (r1232337; 2012-01-17 10:44:56+0200) Maven home: /usr/share/maven-bin-3.0 Java version: 1.7.0_05, vendor: Oracle Corporation Java home: /usr/lib64/icedtea7/jre Default locale: en_US, platform encoding: ANSI_X3.4-1968 OS name: "linux", version: "3.5.2-gentoo", arch: "amd64", family: "unix" 

thanks!

You should add the maven-jxr-plugin to the reportingPlugin section.

<reporting>     <plugins>         <plugin>             <groupId>org.apache.maven.plugins</groupId>             <artifactId>maven-jxr-plugin</artifactId>             <version>2.3</version>         </plugin>     </plugins> </reporting> 

Re run it and enjoy.

BTW, maybe you'll need to run once the jxr:jxr goal to first generate some file that will be used by pmd.
