Jukka Zitting commented on JCR-116:
-----------------------------------
I believe that the IDE integration tools only look at the build/sourceDirectory
element of project.xml. As Maven does not allow more than one source directory
(they do have a good point for this), I unfortunately don't think that the
configuration can be automated.
The generated sources are added to the internal Maven source path by the
maven:addPath element in maven.xml of the attached patch. I don't know of any
automated way to make the path externally visible.
> JavaCC grammar generation to ${maven.build.dir}/generated-src

> Key: JCR-116
> URL: http://issues.apache.org/jira/browse/JCR-116
> Project: Jackrabbit
> Type: Wish
> Components: maven, sql, xpath
> Reporter: Jukka Zitting
> Priority: Minor
> Attachments: jackrabbit-javacc-target-patch.txt
>
> Currently the JavaCC grammars in src/grammar/{xpath,sql} are processed into
> Java source files in src/java/org/apache/jacrabbit/core/query/{xpath,sql}
> where we also have normal version controlled source files. This leads to the
> need to maintain special svn:ignore properties and also the more general
> issue of mixing manually written and automatically generated source files.
> Because of this the "maven clean" command does not (at the moment) truly
> restore your source tree to a "fresh checkout" state.
> I'm proposing (as a wish, you are free to disagree) that the JavaCC grammars
> be generated into Java files within the Maven build directory. The attached
> patch modifies the javacc maven goals to generate files into
> ${maven.build.dir}/generated-src. The modified prepare-filesystem goal also
> adds the generated source path ${maven.build.dir}/generated-src/main/java
> into the maven compile set so that the generated sources are included in the
> normal builds.
> PS. There are a couple of JavaCC generated files that have been intentionally
> modified for Jackrabbit. The ant:delete commands at the end of the
> jacrabbit:generate-*-parser goals specifically remove these generated files.
> It would however be nicer if custom modifications would not be needed.
