Failed to install plugin [blazeds-2.0]. Plugin has missing JAR dependencies.

I would really appreciate if someone could help me resolving this issue. Thanks

I have faced same problem recently on grails 1.3.7. By somehow this problem was reproduced only in Windows but not in Ubuntu. So i just copy ivy cache from Ubuntu to Windows and now it's ok. I don't know can I place this jars on the internet, so anyway you can manually download them from some maven or ivy repository.

Add the following line to the repositories section of your BuildConfig.groovy file:

mavenRepo "https://src.springsource.org/svn/spring-flex/tags/spring-flex-1.5.0.RELEASE/local-repo/"

Adapted from this other SO question.

It is Windows' problem. It looks like a corrupt ivy cache. Just delete ivy-cache folder in .grails. For Windows 7, it's: C:\Users[USER NAME].grails\ivy-cache.

It will be regenerated when you use grails command. Hope it helps.
