Upgrading Build Dependencies

Now that your projects are readily available in a workspace, you must ensure your project build dependencies are upgraded. Your workspace streamlines the build dependency upgrade process by only requiring three modifications:

If you’re upgrading a recently created workspace, only a subset of these tasks may be required.

You’ll start by updating the repository URL.

Updating the Repository URL

Initiating this step in the Upgrade Planner updates the repository URL used to download artifacts for your workspace.

If you’re using a Gradle-based workspace, the repository URL is updated to point to the latest Liferay CDN repository. This is set in your workspace’s settings.gradle file within the buildscript block like this:

repositories {
    maven {
        url "https://repository-cdn.liferay.com/nexus/content/groups/public"
    }
}

Once the repository URL is set to the proper CDN repository, your build dependencies will be downloaded from Liferay’s own managed repo.

For Maven-based workspaces, Maven Central is the default repository, so no action is required.

Updating the Workspace Plugin Version

For the best upgrade experience, you should ensure you’re leveraging the latest Liferay Workspace version so all the latest features are available to you. Initiate this step to upgrade the appropriate plugin.

See the Updating Liferay Workspace article to do this for Gradle-based workspaces manually. For Maven-based workspaces, make sure you set the latest Bundle Support plugin version in your root pom.xml file.

Removing Your Project’s Build Dependency Versions

Since your workspace is leveraging the target platform feature, there is no need to set your plugin’s dependency versions in its build.gradle file. This is because the target platform version you set already defines the artifact versions your project uses. Therefore, if dependency versions are present in any of your projects’ build.gradle files, you must remove them.

Initiate this step to remove your dependency versions from your project’s build.gradle file

As an example of what a build.gradle’s dependencies block should look like, see the below snippet:

dependencies {
    compileOnly group: "com.liferay.portal", name: "com.liferay.portal.kernel"
    compileOnly group: "com.liferay.portal", name: "com.liferay.util.taglib"
    compileOnly group: "javax.portlet", name: "portlet-api"
    compileOnly group: "javax.servlet", name: "javax.servlet-api"
    compileOnly group: "jstl", name: "jstl"
    compileOnly group: "org.osgi", name: "osgi.cmpn"
}

If you have not set the target platform feature in your workspace, see the Managing the Target Platform article for more information.

Great! You’ve successfully upgraded your build dependencies! You likely have compile errors in your project; this is because your dependencies may have changed. You’ll learn how to update that and more next.
