Eclipse Java Debugging: Resolving "Source Not Found" Error

When debugging Java applications in Eclipse, users may encounter the "Source not found" error in the following scenarios:

• Stepping into a file from a different project despite adding it as a dependency
• Stepping into a file from a Maven repository

To address this issue, follow these three steps:

1. Edit Source Lookup Path: Select the "Edit Source Lookup..." option to open the Source Path Dialog. Add the paths to the project or Maven repository containing the missing source files.
2. Select Source Attachment: When stepping into a missing file, an "Attach Source" button appears. Click on it and select the project or JAR containing the source code.
3. Restart Eclipse: After configuring the source lookup paths and attaching source, restart Eclipse to refresh the debugger settings.

With these steps, Eclipse will now be able to locate and debug source files, allowing you to inspect variables and fully navigate the codebase.
