Build tool window

The Build tool window helps you view the output of your builds that were done by IntelliJ IDEA, delegated to Maven or Gradle, and the results of the projects' synchronization.

Build Output tab

IntelliJ IDEA displays the result of your build in the Build Output tab. Depending on a project, the build output shows tasks, goals, and commands that were executed and error messages that were produced.

By default, the tab also displays all successful steps and warnings.

Build a project

From the main menu, select Build | Build Project Ctrl+F9.
Check the results in the Build tool window.

Sync tab

When you open a Gradle or Maven project, the sync is done automatically. Click the Build icon on the status bar to view the results of the sync in the Build tool window.

If you need, you can manually trigger the synchronization of your project.

Reimport a project

Open a Gradle or Maven tool window.
Right-click a project you want to sync and from the context menu, depending on the project, select Reimport Gradle Project or Reimport Maven Project.
Check the results in the Build tool window.

For more information, refer to Maven and Gradle section.

Error handling

When an error occurs during the build process, IntelliJ IDEA displays an error message with the line and column number that could be easily located. If IntelliJ IDEA can locate the error place, it displays a link that you can click and navigate to the needed line in the editor.

When the Build tool window displays multi errors or warnings, it enables you to navigate between the next or the previous problem from the context menu or using the Ctrl+Alt+Down and Ctrl+Alt+Up shortcuts.

If the error occurs during the synchronization process, IntelliJ IDEA displays an error message. IntelliJ IDEA also displays the issue description in the text console and offers a solution if possible.
