Hi

My guess about <trycatch> was right: The stacktrace is eaten and only the exception message is logged (unfortunately, not even debug or verbose flags changes that).

Removing <trycatch> I get the following output now:

Seems like this build opens to many files. ulimit -n gives me a OS limit of 8192 open files.

=> Possible root causes: - a limit on open files that is too low - code that does not properly close files after using them (e. g. some steps before bytecode scan like Java source code import or AST scan leave files open)

What do you suggest (I'd rather not increase the OS limits if I there are other ways to fix that).

Regards

Peter

Hi

I've asked for stack-trace whereas I don't see stack-trace in your log. Which Ant option did you used ? Could you try "ant -v" (extra verbose) ? In order to be clear : exception which you see just wraps another one and would be better to find a line of code where original cause was thrown.

Sorry, but that is exactly what I get when using ant -v -d (i. e. extra verbose & debug; BTW: ant is version 1.8.1). => Either 1) the stack trace is not logged at all or 2) the <trycatch> construct that I use in the ant wrapper (to prevent builds to fail in case sonar is not available or analysis fails) consumes the exception and only logs the exception message.

I will have to modify the ant wrapper to check (2). Updates follow ..
