Description Vadim Mironov

2009-12-11 04:00:17 EST

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.0 (KHTML, like Gecko) Chrome/3.0.195.33 Safari/532.0
Build Identifier: I20091030-1201

I have ant xml build file in my project. If I right click on it, select Run As -> Ant Build... and then go to classpath tab, when I'm clicking Restore Default Entries all Targets tab becomes empty and error is shown "[Targets]: No targets could be determined for the buildfile".

After that if I open xml build file, view fails with an error:

Just tried with empty metro stack distro in fresh workspace and it seems that there is no such problem, but in my main workspace I get it every time i repeat the sequence. Hmmm, don't have any clues what might be causing this behaviour, can somebody work out some explanation from stack trace?
