Scala Eclipse IDE suddenly ignoring breakpoints

I've been using Scala 2.8RC1 and Scala Eclipse plugin for 2.8 RC1 happily for a few days. However, last night after adding a couple jar files to my environment (apache http client jars) the debugger just stopped stopping at breakpoints in scala code.

Java code stops fine at breakpoints. I tried creating a new mimimal scala app breakpoints don't stop. I've tried switching to sun-jre-1.6.0.20 from the openjdk-1.6.18 I had been using. I've switched to the scala 2.8 nightly and also eclipse plugin for scala nightly builds. No luck.

I would greatly appreciate ideas for fix开发者_JS百科es. Rather frustrating as the initial experience with 2.8 was really great.

Says that scala eclipse plugin doesn't stop at breakpoints if you're class is in the default package (no package)

Adding a package and moving my class to it - make the debugger start working again.

It's possible that you've discovered a bug in the Scala tooling for Eclipse. The best place to take the issue is the scala-ide-user list here,

http://groups.google.com/group/scala-ide-user

If you're already sure that you've found a bug you can find instructions for opening a ticket here,

I've just encountered this problem. Code is not in default package. I'm getting a warning about missing line numbers, but apparently that bug has been fixed and I can ignore the warning, per https://scala-ide-portfolio.assembla.com/spaces/scala-ide/tickets/1000155-its-impossible-to-add-line-numbers-debug-info-to-compiled-project#/activity/ticket:

It did seem to stop at breakpoints in the main file, though.
