debug with attached sources: 2 tabs opened ".class" and ".java" [message #494133] Thu, 29 October 2009 06:39 Go to next message

Hi. I have attached the sources to a jar file. Opened a class in editor (the tab name was "SomeClass.class") and put a breakpoint at some function. When the breakpoint hit, Eclipse opend another tab "SomeClass.java" and highlighted the breakpoint line.
This is the same for eclipse 3.4.2 and 3.5. I even reinstalled them.

The breakpoint icon isn't visible in the ".java" tab, only the highlighted line.

When hovering the mouse pointer, I can see the function arguments values, but they're not evaluated in the "Expressions" view.

Breakpoint conditions code assist works, but the condition isn't respected. The breakpoint always hits on 3.4.2.
On eclipse 3.5 after I add conditions, it shows the error message: "Unable to compile conditional breakpoint - missing Java project context".

No news on this question?

I observe the same problem with Eclipse 3.5 (some plugins are not yet 3.6 ready). With Eclipse 3.3 conditional breakpoints work perfect. 3.5 results in the same compilation error.

Just bumped into this with Eclipse 3.6. I can confirm the very same behavior. I have downloaded the sources via m2eclipse plugin, but I don't think it matters.

This is the only relevant thread I get on this issue. Has anybody found a workaround for this (other than removing the sources from the project, which I don't want to do)? Or has a ticket been opened perhaps?

No, they are the same (at least should be, as maven downloads a source package that responds the version number of the JAR)

I was facing the same problem and then found out that the source zip file which I was attaching to the jar file was from a project which was not a java project. I converted that project to a Java project and the problem was solved.
