PMD Eclipse Plugin

Build Status

Eclipse Update Site:

How to contribute

You can contribute by testing the latest version, creating bug reports, or even forking the repository on github and create pull requests. Any contributions are welcome!

Testing the latest version

Simply build the plugin locally using maven:

./mvnw clean verify

You'll find the zipped update site in the folder net.sourceforge.pmd.eclipse.p2updatesite/target/. Point eclipse to the zip file in this folder as an update-site and install the latest SNAPSHOT version.

Bug Reports

Please file any bug reports in the bug tracker at github:

https://github.com/pmd/pmd-eclipse-plugin/issues

GitHub Repository

Just fork the the GitHub Repository pmd/pmd-eclipse-plugin and create a pull request.

https://github.com/pmd/pmd-eclipse-plugin/

To get started, see also the next section.

Short Developer's Guide

Compilation

Simply run ./mvn clean verify. The plugin's update site will be generated in net.sourceforge.pmd.eclipse.p2updatesite/target/repository. You can use this directory as an update site to install the new plugin version directly into your Eclipse.

Importing the projects in Eclipse

Make sure you have the Maven Integration (m2e - http://eclipse.org/m2e/) installed. Then you can import Existing Maven Projects. You should see 6 projects:

  • net.sourceforge.pmd.eclipse - that's the feature
  • net.sourceforge.pmd.eclipse.p2updatesite - generates the update site
  • net.sourceforge.pmd.eclipse.parent - the parent pom project
  • net.sourceforge.pmd.eclipse.plugin - the actual plugin code
  • net.sourceforge.pmd.eclipse.plugin.test - the (unit) tests for the plugin
  • net.sourceforge.pmd.eclipse.plugin.test.fragment - an example extension of the plugin used during the tests

Debugging

You can run eclipse with debugging enabled and connect to it via remote debugging:

eclipse -data workspace-directory -vmargs -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000

Releasing and updating the official eclipse update site

From now on, we use bintray for hosting the eclipse update site. There is a nice blog post by Lorenzo Bettini, which explains how it is done. There is also an example repository on github.

Have a look at the net.sourceforge.pmd.eclipse.p2updatesite module, there you see

  • a profile release-composite which enables the steps
  • the ant script bintray.ant which is used to upload and download the site
  • the ant script packaging-p2composite.ant which is used to modify the metadata of the p2 repo locally before uploading

The release happens in two phases:

  1. Update the repository locally to prepare the new version:
    • Update the changelog
    • Update the versions
    • Create a tag
    • Update the changelog for the next version
    • Update the versions
  2. Push the changes and the tag. The travis build will then publish the new version on bintray and github releases

Script

# Pick a release BUILDQUALIFIER (e.g. v20170401-0001) and update versions
# E.g. version is: "4.0.13" and BUILDQUALIFIER is "v20170401-0001".
# The complete version of the plugin will be "4.0.13.v20170401-0001
export BUILDQUALIFIER=$(date -u +v%Y%m%d-%H%M) && echo $BUILDQUALIFIER

# Pick the version of the new release and the next development version
export VERSION=4.0.15
export NEXT=4.0.16

echo Update the ReleaseNotes with the release date and version:
echo 
echo "## $(date -u +%d-%B-%Y): $VERSION.$BUILDQUALIFIER"
echo
echo
echo "Press enter to continue..."
read
mvn -Dtycho.mode=maven org.eclipse.tycho:tycho-versions-plugin:set-version -DnewVersion=$VERSION.$BUILDQUALIFIER
sed -i -e "s/$VERSION.qualifier/$VERSION.$BUILDQUALIFIER/" net.sourceforge.pmd.eclipse.p2updatesite/category.xml
git commit -a -m "Prepare release pmd-eclipse-plugin $VERSION.$BUILDQUALIFIER"
git tag $VERSION.$BUILDQUALIFIER
echo "Create (temporary) release branch"
git branch pmd-eclipse-plugin-rb-$VERSION

echo
echo Update the ReleaseNotes and add a next version entry:
echo "## ????: $NEXT.v????"
echo
echo
echo Press enter...
read

echo "Updating version in master to next"
mvn -Dtycho.mode=maven org.eclipse.tycho:tycho-versions-plugin:set-version -DnewVersion=$NEXT-SNAPSHOT
sed -i -e "s/$VERSION.$BUILDQUALIFIER/$NEXT.qualifier/" net.sourceforge.pmd.eclipse.p2updatesite/category.xml
git commit -a -m "Prepare next pmd-eclipse-plugin development version $NEXT-SNAPSHOT"

echo Checkout the release branch and build the plugin
git checkout pmd-eclipse-plugin-rb-$VERSION

mvn clean verify

echo
echo "Please test now!!!"
echo
echo Update-Site: file://`pwd`/net.sourceforge.pmd.eclipse.p2updatesite/target/net.sourceforge.pmd.eclipse.p2updatesite-$VERSION.$BUILDQUALIFIER.zip
echo
read

echo
echo "Publishing now..."
git checkout master
git branch -D pmd-eclipse-plugin-rb-$VERSION
git push origin master
git push origin tag $VERSION.$BUILDQUALIFIER

echo Done.

Also, don't forget to create a News and verify, that the zipped update site has been uploaded to GitHub Releases.

You can use the following template:

PMD for Eclipse $VERSION.$BUILDQUALIFIER released

A new PMD for Eclipse plugin version has been released.
It is available via the update site: <https://dl.bintray.com/pmd/pmd-eclipse-plugin/updates/>

* Release Notes: <https://github.com/pmd/pmd-eclipse-plugin/blob/$VERSION.$BUILDQUALIFIER/ReleaseNotes.md>

Updating the used PMD version

The parent pom contains the property pmd.version. This is used inside the plugin module, to resolve the dependencies. In order to change the PMD version, change this property and rebuild (mvn clean package). In case PMD has some changed (added/removed) transitive dependencies, you'll need to update n.s.p.e.plugin/META-INF/MANIEFEST.MF as well. All transitive dependencies are copied into the folder n.s.p.e.plugin/target/lib during the build.
