NPE in STS 2.3.0 on Mac OS 10.6.2

[dan.baumann]

Yesterday, I started getting NPEs from inside STS, rendering STS practically useless.

I'm using STS 2.3.0 on Mac OS 10.6.2, and all my projects are Maven-based.

Installing a fresh copy of STS in a fresh user account resulted in the same problems. I also updated M2Eclipse from their update site at http://m2eclipse.sonatype.org/update-dev/, as recommended in another thread, but to no avail.

I wouldn't mind reverting to STS 2.2.1 for now, but there seems to be now download available anymore.

Below, I included the stack trace for the first of many errors from the STS error log view.

If anyone could help me with this, it would be greatly appreciated. I'd be glad to provide more information if required.

Thanks,
Dan

Hi Dan,

can you please check your org.eclipse.jdt.launching_3.5.0.v20090527.jar to see if it contains a lib/launchingsupport.jar. If it doesn't or the name is different can you please re-download STS from the website and install again.

This issue was/is caused by a broken installer.

Thanks a million Christian,

My org.eclipse.jdt.launching_3.5.0.v20090527.jar did indeed not contain lib/launchingsupport.jar, only lib/launchingsupport.jar.pack.7z.

I re-installed STS using a fresh installer download and it all works as expected.

Now back to work..

Regards,
Dan
