Install or Update the Force.com IDE Plug-In for Eclipse

The Apex Debugger is part of the Force.com IDE plug-in for Eclipse. Before you set up the Debugger, install or update the Force.com IDE.

Force.com IDE is in a maintenance-only state. We still provide support for the product through our official channels, but updates prior to October 12, 2019 will be only for critical security issues that arise. On October 12, 2019, we will no longer provide support or updates of any kind for Force.com IDE. On that date, we will also begin archiving documentation and removing download links for the product. We recommend that you start migrating to Salesforce Extensions for Visual Studio Code or one of the great tools made by our partners. For more information, see The Future of Salesforce IDEs on the Salesforce Developers Blog.

Warning

The Apex Debugger implementation for Eclipse works only with sandbox orgs. To debug scratch orgs, install Apex Debugger for Visual Studio Code.
