PMD release walkthrough:

Make sure code is up to date and everything is in svn:

$ mvn clean
$ svn update
$ svn status

Ensure all the new rules are listed in a rulesets/releases/<version>.xml file.

Update pom.xml:
* remove "SNAPSHOT" from the version
* make sure that scm/*connection are pointing to the subversion tag, that will be created soon.

Update the "download" and "what's new" link in navigation.xml.

Update version/release info in etc/changelog.txt.

$ mvn verify post-site    (order of targets DOES matter)

Unzip and test manually (just to be on the safe side of the road):

./bin/pmd.sh ~/tmp/Test.java xml java-unusedcode
./bin/pmd.sh ~/tmp/Test.java html rulesets/unusedcode.xml

Check in all (version) changes to trunk:
$ svn ci -m "pmd: Prepare pmd release <version>"

Create a tag from trunk:
$ svn cp https://pmd.svn.sourceforge.net/svnroot/pmd/trunk/pmd https://pmd.svn.sourceforge.net/svnroot/pmd/tags/pmd/pmd_release_<version>

Note:
If you see a bug and fix it, you can delete the release using the following command (and then
recreate the tag):
$ svn delete https://pmd.svn.sourceforge.net/svnroot/pmd/tags/pmd/pmd_release_<version>

Update pom.xml in trunk:
* increment the version and add "SNAPSHOT"
* make sure that scm/*connection are pointing to trunk.

Check in the changes to trunk:
$ svn ci -m "pmd: Increment version to the next SNAPSHOT"


Public the release on sourceforge:
- Go to Admin, File Releases, Add release
- Paste stuff into the changelog/readme boxes
- Add the pmd-<version>-bin.zip file
- Add the pmd-<version>-src.zip file

Upload command below will create and upload the maven artifacts to sourceforge. Login info
for 'pmd-repo' and 'pmd-site' must be defined in ~/.m2/settings.xml
(see the file available in tools/config/m2.settings.xml):

$ ssh your_sf_login,pmd@shell.sourceforge.net create
...
$ mvn source:jar javadoc:jar deploy -Psf-release    (order of target DOES matter)

(In order to be able to upload the artifacts and the site to sourceforge, you need to have a interactive shell opened
before)

Upload the site:

$ mvn site-deploy -Psf-release

Shutdown the sourceforge shell:

$ ssh your_sf_login@shell.sourceforge.net "shutdown"

Social side of release:
1) Submit news to SF
    Go to http://freshmeat.net/

2) Facebook, Google+, Twitter, LinkedIn and Xing (add whatever you feel is missing here...)
