Question

I’m trying to upgrade Grails to version 2.2.0. I used gvm and installed Grails 2.2.0. After this I changed my project in GGTS to use Grails version 2.2.0 and Groovy version 2.0.0. But when I finally tried to run the project, I got the following error:

Error occurred during initialization of VMError opening zip file or JAR manifest
missing : null

agent library failed to init: instrument 

What is the problem?

I had the same problem when I started using Grails 2.2.0 – The solution Ian mentioned works, here is the link to the issue and resolution that occurred in my project

Grails 2.2.0 error

Added on 1/15/2013 Other suggestions based on 2.2.0/ivy cache issues

I am running on windows, a couple of things to try.

1. Based on your error message seems like the issue might be related to the Ivy cached, I would suggest cleaning that out using the clean command.

2. I would also go ahead and delete the Icy cache folders on your machine at \ivy-cache(after backing it up just in case)

3. Read grails documentation at http://grails.org/doc/2.0.0/guide/gettingStarted.html, refer to section 2.3 regarding Ivy cache – there might be issues running 2.x and 1.x grails projects side by side.
4. When install, I do not have to install groovy explicitly – I just install grails and that take care of the groovy code implicitly. Is that possible for you to do? To rule out dependency issues?
5. On my version of grails I have the groovy version showing up as 2.0.5 – I assume you meant grails 2.2.0 – can you ensure that you have a groovy version installed with is compatible with grails 2.2.0?
6. If possible try your code on a fresh device where grails has not been installed before. This is to rule out interference due to other existing issues
