Jaspersoft Studio not starting on Mac

[gdoe6545]

Studio 5.5.0 on Mac OS X 10.9.1 won't start for me I get the splash screen saying "Loading Workbench" but it hangs and won't go any further.

No error messages in Console.

Any ideas?

Hi,
please try to locate the log file that should be in ~/JaspersoftWorkspace/.metadata/.plugins/org.eclipse.ui.workbench/log

Just in case try to start it from the command line like this:

1. Open Terminal window
2. Move to the Jaspersoft Studio install location: i.e. /Applications/Jaspersoft Studio 5.5.0.final/Jaspersoft Studio.app/Contents/MacOS
3. Run like this: ./Jaspersoft Studio -debug -consoleLog

You should see a more detailed log of what is happening. And this could give us some interesting info.

Best regards,
Massimo.

I got it working by completely removing '.metadata' I'll keep the above in mind if I have problems in the future.

 

But I did then run into another problem, Studio was starting up under the 1.6 JRE even though my default JRE is 1.7 and I was getting "Unsupported major.minor version 51.0" build errors.

 

I had to remove this line in "Jaspersoft Studio.ini" to get things working:

-vm /Applications/Jaspersoft Studio 5.5.0.final/features/jre.macosx.cocoa.x86_64.feature_1.7.0.u25/jre/Contents/Home

 

After removing this my templates compile correctly and Studio uses the 1.7 JRE.

I ran into the same problem os a separate machine and I can confirm the hang on startup is due to Studio running under the wrong JRE (1.6) when I have classes in my workspace compiled under 1.7.

 

Removing the -vm option as above allowed Studio to start correctly.
