Package org.springframework.aop.framework does not exist - spring

Question

I have installed grails and am trying to compile with the default version of cache:1.1.6 and I'm getting these errors within the plugin code.
Can any one help me with which dependency is broken in the repository - I havent even used the cache yet - just defined it in BuildConfig.groovy
I understand "By default, Grails will not only get the JARs and plugins that you declare, but it will also get their transitive dependencies" so why would I have to declare the dependencies?
Compilation error: startup failed:
Compile error during compilation with javac.

Odd this is with a new Grails application? It sounds like it could be a corrupt Maven cache issue. Try doing:
$ rm -rf ~/.m2/repository
Otherwise, to declare the dependency explicitly edit BuildConfig and add:
compile 'org.springframework:spring-aop:4.0.5.RELEASE'
To your dependencies block.
