Introduction

Attach to local process feature allows you to debug a project which you are developing in IntelliJ IDEA, but (for some reasons) are not able to launch directly from your IDE.

Attaching to local process

To attach to a local process, follow these general steps:
  1. Launch the process intended for debugging. You can do it from operating system or using the IntelliJ IDEA terminal.
  2. To find the process to attach to, do one of the following:
    • On the main menu, choose Run | Attach to Local Process:

    • On the main menu, choose Help | Find Action or press Ctrl+Shift+A. In the list of actions that appears, find the desired action by typing the first letters, and select it:

  3. From the list of available processes that appears, select the desired process. Simplify your search by typing the first letters of its name or PID

  4. Proceed with debugging the same way as you usually do it in IntelliJ IDEA (set breakpoints, step through, pause and resume the process, evaluate expressions etc.)
  5. When finished, detach the process: select the Run | Stop or click the Stop the process button images/stop.gif of the Debug Tool Window .
