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. The decompiler plugin will ignore your debug mode choice. The decompiler plugin implements the JavaDoc feature.
If the jar binds javadoc in the Eclipse workspace, the api document will display on the decompiler viewer. Jad and JD don't support Java 8. If you choose them as the default decompiler, when the class compliance level is Java 8, the decompiler plugin will decompile the code by FernFlower automatically.
But the decompiled source codes of these decompilers are not the same, you can choose the one that works best for you. This is a utility feature. You can export the decompiled codes from one or more classes, even the whole jar. The decompiler plugin can decompile the class file outside of the Eclipse IDE as well. Improve this question.

There are various solutions: You can download the sources and attach them select the dependency in the Package Explorer, open the Properties dialog for it, set the path under "Java Source Attachment" If you don't have the source, install JADClipse Use "Step Over" F6 instead of "Step Into" F5 If you accidentally stepped into some code, use "Step Return" F7 to run the whole method and resume debugging after it has returned.

You can try JADClipse At least you will see the code, and be able to step return and step resume more easily. Cyril Cyril 4 4 bronze badges.

While debugging a java app in eclipse I receive a " Source not found " error in two cases: Stepping in to a file in a different project which is already imported Stepping in to a file in an installed maven repository The files are there, but eclipse won't step into them, instead it shows a button to " attach source " I tried attaching which opened a dialog to define a variable?!

Thanks Douglas Frari — stephen ebichondo. Works like a charm. Until I did that it seemed as though it still couldn't get the sources. I've been dealing with this on and off for months. This worked perfectly. Show 9 more comments. Eclipse debugging works with the class actually loaded by the program. Aaron Digulla k gold badges silver badges bronze badges. ACV Well, yes. Perhaps it is not as elaborate as you would like - could you let me know what you would like to have explained better?

Classes from project's build path, added manually requires that you manually attach the associated source. The source can reside in a zip or jar file, in the workspace or in the filesystem. Eclipse will scan the zip, so your sources doesn't have to be in the root of the archive file, for example.
Classes, from dependencies coming from another plugins maven, PDE, etc. In this case, it is up to the plugin how the source will be provided. More information can be found here and here. This feature should be enabled m2eclipse preferences the option was named something like " Download source and javadocs ".
For other plugins, you'll need to consult their documentation Classes, which are loaded from your project are automatically matched with the sources from the project. But what if Eclipse still suggest that you attach source, even if I correctly set my classes and their sources: This almost always means that Eclipse is finding the class from different place than you expect.
Eclipse doesn't find anything at all, when breakpoint is hit: This happens, when you are source lookup path doesn't contain the class, which is currently loaded in the runtime. I cannot see the variables when I hit a breakpoint or it just opens the source, but doesn't select the breakpoint line: This means that in the runtime, either the JVM or the classes themselves doesn't have the necessary debug information.
Eclipse source viewer shows different lines than those that are actually executed: It sometimes can show that empty space is executed as well. Danail Nachev. Excellent answer! See this other stackoverflow item for details: stackoverflow.
Maybe you can take a look at this - I'm out of things to try already.. Good to know. Lot of theory, but no practical solution. Vering Vering 8 8 silver badges 16 16 bronze badges. I fought with this issue quite a long time then I tried to rebuild project with mvn clean eclipse:eclipse and it helped. Unless you know how the classpath in Eclipse works, this approach is not recommended. Only this works for me too!
Besides, the m2eclipse plugin will add the project dependency only in "Maven Dependencies" which in Libraries tab, and the debugger cannot find. I don't know what happened but after executing this I don't see my maven dependencies under "Maven Dependencies" anymore.
I was facing the same issue,I followed the bellow steps. Now You should see the bellow screen. Varun Varun 5, 19 19 gold badges 76 76 silver badges bronze badges. Use this approach if Eclipse can't load classes from the Java runtime any class where the full type name starts with java.
String — Aaron Digulla. Remove the existing Debug Configuration and create a new one. That should resolve the problem. Rajneesh Sekharmantri Rajneesh Sekharmantri 61 1 1 silver badge 1 1 bronze badge. I followed this and it worked.
