Blackberry - "[projectname].debug file is missing" and "I/O Error: Cannot find program "jar"

Question

I'm running eclipse with the Blackberry Java Plug-in, working on a 1.4.5 Blackberry project. The project has been building and debugging in the emulator normally until I started getting:

A prompt saying "[projectname].debug file is missing".

A message in the Blackberry Packaging Console saying "I/O Error: Cannot find program "jar": CreateProcess error=2."

Anyone have any ideas what could be causing this?

Answer 1

It turns out that there can be a few different causes. In some instances, hitting the 100 class limit in the project can cause this.

In my case, the Environment Variable for Path in Windows > System Properties had disappeared. Something to note is that when you put it back in (in my case "c:\program files\java\jdk1.6.0_18\bin") it needs to be the first entry in the path variable.
