DS 5.3 launching failure

Hi all,

Recently I updated my Developer Studio to the newest version 5.3 by update checking inside DS. But after the installation I failed to launch the DS. The prompt letting me select working folder showed up but after pressing launch, the prompt vanished.

Is that a known issue? Is there any workaround or I have to reinstall it? Will re-installation affects the framework folders under DS working directory? The error log is appended..log (778.6 KB)

A lot of thanks.

Best regards,

Lichen Yao

Hi @lichen

We did test the upgrade scenario, and didn’t reproduce this problem.
Something should have gone wrong during your update. It looks like legacy plugins installed with DS 5.2 were not removed correctly.

That said, here are several tricks you can try to recover:

  • either use the garbage collector to clean legacy plugins: devstudio -application org.eclipse.equinox.p2.garbagecollector.application -profile DefaultProfile
  • or clean manually the legacy plugins: remove all com.swi.ebs.legato.parser.XX.jar plugins (+ any other com.swi.XX with 5.2 version) and restart DS
  • if this is not working, I’m afraid you’ll have to reinstall.
