Subject Re: Build error in trunk due to conflicting commons-beanutils depenencies
Date Tue, 08 Oct 2013 13:54:45 GMT
Hi Ate,

Thanks for the suggestion. That makes sense.
So, I think I should do the following:
- Add exclusion(s) on commons-beanutils-core after looking into all transitive dependencies.
- Add commons-beanutils dependency explicitly wherever used.
- Check all for any problematic transitive dependencies.

I'll create an issue for this and fix it soon.

Cheers,

Woonsan

The API, MethodUtils#invokeStaticMethod() [1]

here, but I think we should add the explicit dependencies in components/jetspeed-portal/pom.xml
like the following:
