crash - Eclipse workspace crashes on startup

Question

I am using Spring Tool Suite(STS) 3.0.0 release (eclipse.buildId=3.0.0.201208091018-RELEASE-e42). It was running fine for a couple of months but lately my main workspace is crashing on splash screen with error as shown in last part of this post.

I have tried 'STS.exe -clean' and reverting installation(via new workbench) to a earlier configuration .. but nothing seems to work.

I was driving it as a single tool (i.e. almost all dev. related tasks even like connecting to server, database) so this is very frustrating :-(.

Any help would be greatly appreciated.

Answer 1

I faced the same problem. I followed these steps and it's working fine,

1. Go to your workspace e.g. C:Workspace

2. Then open .metadata.plugins folder from your workspace.

3. Delete below 2 folders,

   • org.eclipse.e4.workbench
   • org.eclipse.equinox.p2.ui.sdk

Eclipse should start after this.
