At this point, you might simply try to run the application by navigating to the main method and clicking the play button:

… and configuring the input arguments to translate some text from English to French by editing the newly created run configuration:

Run the program again, and this time you get the following error:

As you may have already guessed, you’re missing authentication rights to access the Cloud Translation API from your local machine. To overcome this, you’d normally have to go through the following steps:

  1. Enable the service on your Google Cloud Platform (GCP) project
  2. Create a new service account with the appropriate roles for accessing the service
  3. Update your local run configuration with the necessary environment variables to access the service

Thankfully, the Cloud Tools for IntelliJ plugin can help. In IntelliJ, navigate to the Cloud Tools menu item under “Tools > Google Cloud Tools > Add Cloud libraries …”:

Select the Cloud Translation API and your GCP project, and click “Add Cloud Libraries”:

In the confirmation window that appears, you can see that Cloud Tools for IntelliJ takes care of enabling the API and creating the service account for you:

Lastly, select the run configuration that you created earlier so that the plugin can inject the necessary environment variables for accessing the Cloud Translation service from your local machine:

Run the program again and your input text is successfully translated from English to French using the Cloud Translation service:

The Cloud Tools for IntelliJ plugin also assists with the following:

  • Adding Java client libraries to your Maven pom.xml if they are not already present
  • Writing a Bill of Materials (BOM) to your pom.xml to help avoid dependency version conflicts
  • Detecting and acting on potential misconfigurations, including a missing BOM, through pom.xml file inspections with quick-fixes

The Cloud Tools for IntelliJ plugin provides many more features to help optimize your development workflow including support for Google App Engine, Stackdriver Debugger, Cloud Repositories, and Cloud Storage.
