> Robert Brehm recently posted a question on the Maven Users list (subject
> "Javadoc plugin issue") about using the 1.5 Javadoc when his JAVA_HOME is set
> to 1.4. He is using the maven-compiler-plugin to specify the 1.5 compiler and
> expected the Javadoc plugin would pick that up and use it automatically, or
> at least offer a way to configure the Javadoc plugin directly. I got
> interested in the issue and wrote some code to support this functionality.
> This is my first official foray into plugin development so I appreciate your
> comments etc. Also I'm still trying to figure out the plugin testing aspect
> so I haven't included tests with this first code drop... I'm not entirely
> sure how to properly develop unit tests for this because it is very
> environment-dependent. I did however include a sample pom.xml with the new
> configuration parameters -- I've tested it myself on Windows with a small app
> (JAVA_HOME set to 1.4 and pom.xml config pointing to 1.5) and it used the 1.5
> javadoc binary as configured.
> I don't like having to include the <javadocVersion> node in the configuration
> but org.apache.commons.lang.SystemUtils doesn't know how to decipher the
> Javadoc version, only the Java version. And I was going to grab the Javac
> specified in maven-compiler-plugin and use it to find the Javadoc executable,
> then fork Javac to find the version etc, but decided that was just too much
> work for right now... If you want to go down that path, go for it, I'm just
> not sure if its worth the effort. ;-)
