Building from source

  • Check out the sourcecode
    git checkout closure-compiler-maven-plugin
  • build using Maven
    cd closure-compiler-maven-plugin
    mvn clean install -Dmaven.test.skip=true -B -V -fae -q -T2
    mvn -e verify -B

    The above will first install a copy of the plugin in your local maven repository so that it is available for running the integration tests of the second command.

    Checkout the .travis.yml or the appveyor.yml for the latest instructions on this.

Updating dependencies

Use the following commands to check for dependency (and plugin) updates:


mvn -U org.codehaus.mojo:versions-maven-plugin:2.5:display-dependency-updates

to check for plugin updates and run:

mvn -U org.codehaus.mojo:versions-maven-plugin:2.5:display-plugin-updates

to check for plugin updates.

Creating a Release

Assuming the requirements for pushing to the OSRRH repository are set up, eg. account, gpg signature,... use the following commands:

mvn -Prelease clean release:clean release:prepare
mvn -Prelease release:perform

Note that the nexus-staging-maven-plugin will throw an exception Unhandled: Missing staging repository: nlgeodienstencentrum-... because we're deploying straight away during release.

Then (optionally) deploy the site to github:

cd target/checkout
mvn site-deploy

Update and push the release notes to reflect the new release cycle.

cd ../..
mvn release:clean clean

And then update the release notes for the next release.
