# Connect the Java Debugger in Anypoint Studio

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Studio disconnects the Java debugger by default. Connect it in the Studio preferences if you need to
debug Java code in your Mule project.

1.  Open the preferences view in the manner appropriate to your OS:

    - In macOS, either navigate to **Anypoint Studio** > **Preferences…​** or press `cmd + ,`.

    - In Windows and Linux, navigate to **Window** > **Preferences…​**.

2.  Expand **Anypoint Studio** in the left navigation bar, and select **Debugger**,

3.  Select **Connect Java Debugger**.

4.  Select **Apply and Close**.

Note that connecting the Java debugger in Studio can cause performance degradation in your
subsequent redeployments.
