Testing Gradle Plugin Before Pushing to GitHub

A change to JUnit 5's gradle plugin usually takes two roundtrips since the junit5 build has to get the plugin from https://oss.sonatype.org/content/repositories/snapshots. If you want to test the plugin without deploying it first, you can follow a few steps:

Step 0:

Modify JUnit5Plugin and JUnit5Extension as necessary.

Step 1:

$> gradle clean install

This builds and installs the junit-gradle snapshot JAR in your local Maven repository.

Step 2:

Make changes to junit5 configuration blocks in Gradle build files as necessary.

Uncomment // mavenLocal() in the buildscript section of build.gradle in the root project.

$> gradle clean test --refresh-dependencies

This will execute the junit5Test tasks against the junit-gradle snapshot JAR in your local Maven repository (using your local changes from Step #0).

Step 3:

Make sure mavenLocal() in the buildscript section of build.gradle in the root project is commented out.

$> gradle clean test --refresh-dependencies

This will pull down the latest snapshot from the Sonatype snapshot repository (i.e., stop using your local junit-gradle snapshot JAR).
