Trying to run a Grails project with Run as> Grails command (run-app). I get this error:
Error opening zip file or JAR manifest missing : null
Error occurred during initialization of VM
agent library failed to init: instrument
I installed the Groovy 2.0 plugin, JDK 1.6.0_44
This project runs form the Grails command line with the "grails run-app" command.
It is quite difficult to understand if it is a project configuration issue or a real problem with STS. The message is cryptic. Unfortunately, that just prevents me from using STS.
