 ## Testing Local Changes with an Existing Project
 A common development task is to modify a plugin and then test it with an existing project.
 
-To do this, first modify the project as necessary, and then build and publish the plugins to the local Maven repository:
+To do this, first modify the project as necessary, and then build and publish the plugins:
 ```bash
-./gradlew publishToMavenLocal --no-parallel
+./gradlew publishAllPublicationsToCommonRepository --no-parallel
 ```
+The above command publishes to a "common" repository located at `build/common-repo`.
 
-Next, update the plugin version string in the project build files.
-The version can be found manually by searching for the published artifacts in `~/.m2/repository/org/graalvm/buildtools/native/`, or alternatively by checking the `nativeBuildTools` property [here](gradle/libs.versions.toml).

-Then, run your build as usual. Gradle/Maven should find the plugin in the local repository and use it for the build.
+Then, run the Maven command with the `-U` flag to force Maven to use an updated snapshot (e.g., `mvn -Pnative package -U`).
