Description mindjoy 2014-07-21 20:24:46 UTC 
I have Maven projects which are built with "mvn clean install". I also have "Generate debugging info" checked in the projects properties. However, in some classes I get the above message when trying to set up a breakpoint, but in some the breakpoints can be set without problems.
Comment 1 Martin Entlicher 2014-07-22 15:19:59 UTC 
Then it should be analyzed why the compiler does not include the line number information into the class files in the Maven project.
Are you sure that the affected classes are not from some library that could be compiled without debugging info?
Comment 2 Martin Entlicher 2014-07-22 15:22:29 UTC 
It can be easily verified that the debuggin info is present in the class files via: javap -l <class file>
Comment 3 mindjoy 2014-07-28 17:30:23 UTC 
The following is the result of javap -l on the class and method I am interested in;

However, NetBeans still does not allow me to create a breakpoint on line 174 here.

Not able to submit breakpoint LineBreakpoint ...
...
reason: No executable location available at line 174

Comment 5 Martin Entlicher 2014-09-12 13:23:58 UTC 
Thanks for the info. The LineNumberTable is there, therefore debugger should be able to submit breakpoints.
Is it possible to provide some sample project so that we can test it and locate the bug? Please include the compiled classes as well. Thanks.
Comment 6 mindjoy 2014-09-12 13:37:03 UTC 
Unfortunately I am not working on this project anymore (I changed client) and don't have access to the code.

If there is anybody out there with similar problems, please submit sample code.
Comment 7 Martin Entlicher 2014-09-12 14:19:43 UTC 
Unfortunately, this is the only report that we got about this problem.
Therefore resolving as incomplete, please reopen if you encounter the problem in the future again and include some sample project with the class files.
