Snapshots and Releases

Snaphots and releases are automatically published to Maven Central using GitHub Actions.

A release is performed with the following steps:

• Publish the draft release. There should be already a draft release created, edit and publish it. The Git Tag should start with v. For example v1.0.0.
• Monitor the Workflow to check it passed successfully.
• Celebrate!

Contributing tips and tricks

Running integration tests

You can run integration tests by executing mvn verify

If you want to run individual tests, you can execute mvn verify "-Dinvoker.test=dockerfile*". In this case, dockerfile* will match all test projects under src/it folder with a name that starts with "dockerfile".

Debugging

To debug the plugin, you first need to publish a snapshot to your Maven local:

$ mvn install

You can skip execution of integration tests by adding -Dinvoker.skip=true to the command line.

Then you need a sample application. The one at examples/java is the most up-to-date, but you can in principle generate a new one from Micronaut Starter. Then, change its pom.xml to set the following property:

<micronaut-maven-plugin.version>1.1.5-SNAPSHOT</micronaut-maven-plugin.version>

Pointing to whatever snapshot version you published before.

Finally, from the sample application folder, run the Maven goal you are interested into with mvnDebug instead of mvn:

mvnDebug package -Dpackaging=docker

Then in your IDE, attach a remote debugger to port 8000.
