I thought I'd try out the html5-showcase project (http://git.springsource.org/greenhouse/html5-showcase).

I've followed the instructions as per the README but I get the following error in my maven build (I even tried with the exact same Maven version as stated in the readme, 2.2.0):

Code:
[INFO] [aspectj:compile {execution: default}]
[ERROR] can't determine superclass of missing type org.springframework.cache.interceptor.CacheAspectSupport
when batch building BuildConfig[null] #Files=48 AopXmls=#0
 [Xlint:cantFindType]
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR

[INFO] Compiler errors :

when batch building BuildConfig[null] #Files=48 AopXmls=#0
 [Xlint:cantFindType]
Any ideas?
