Even if the class is in the workspace, it can be invisible to the launch configuration, because Eclipse follows the source lookup path strictly and attaches only the dependencies of the project, which is currently debugged. An exception is the debugging bundles in PDE.
This happens, when you are source lookup path doesn't contain the class, which is currently loaded in the runtime. Even if the class is in the workspace, it can be invisible to the launch configuration, because Eclipse follows the source lookup path strictly and attaches only the dependencies of the project, which is currently debugged.
Unfortunately Eclipse Debugger doesn't work with class realoaded in this way. In order to make sure that Eclipse will work fine with the class after changes you have to restart your web application container. JRebel doesn't recompile code, it operates with *class files.
I am doing remote debugging of a Java application and using the debug view of Eclipse. The basic debugging process is working fine and I can see the method stack traces in debug view at the relevant breakpoints.
Open project explorer and then expand your project. Then, look for maven dependencies and expand this tree view. Now, you can expand any jar file and see list of available classes and by pressing enter on any of them, Eclipse will decompile the source for you and you can set a breakpoint.
Attaching source files when debugging with EclipseClick Edit Source Lookup Path… from Source not found to open the Edit Source Lookup Path dialog. Source not found. ... Click Add button from the Edit Source Lookup Path dialog. ... Select Java Project as the source. ... Select projects. ... Confirm configuration.
The solution was to enable it again, start a debug session, the breakpoint is hit and shown in the UI, then disable again the option. There is also another simpler way that will make Eclipse show the debugging highlight at the breakpoint or rather refresh the debugging UI to work as it should.
In the Eclipse settings under General->Error Reporting there is the option "Enable debug mode".
There are two ways to debug a class file. The first way is to set the decompiler preference, and to realign the line number. The second way is to check the debug mode in the decompiler menu bar. When your Eclipse workspace is in debug perspective, the debug mode becomes the default.
Debugging a JAR FileTreat the class path specified after the ! character as the main class (for example, /myclass.class or /x/y/z.class)Add the name of the JAR file ./myjar.jar, /a/b/c/d/e.jar, or /a/b/c/d.jar to the class path.Begin debugging the main class Note –

To put breakpoints in your code, double click in the left margin on the line you want execution to stop on. You may alternatively put your cursor in this line and then press Shift + Ctrl + B . To control execution use the Step Into, Step Over and Step Return buttons. They have the shortcuts F5 , F6 and F7 respectively.
A Debug value indicates a debug configuration. When you start the app (press the green arrow or F5) in a debug configuration, you start the app in debug mode, which means you are running your app with a debugger attached. This enables a full set of debugging features that you can use to help find bugs in your app.
You should turn to "Project->Properties" and then select "Run/Debug Settings". There you should be able to configure your project so that it always "runs" the same.

Java Debugging with Eclipse. Debugging is the process of identifying and fixing any issues in the source code of a program. Modern IDEs like Eclipse provide debugging tools that make it easier for developers to walk through their code interactively and inspect it to spot and resolve any issues.
