Jason van Zyl closed MNG-2481.
------------------------------
Resolution: Fixed
We decided the caching should not be done in the project builder. It is being
done at a session level in the reactor manager now.
> project builder should make the processed project cache configurable

> Key: MNG-2481
> URL: http://jira.codehaus.org/browse/MNG-2481
> Project: Maven 2
> Issue Type: Bug
> Components: Performance, POM
> Affects Versions: 2.0.4
> Reporter: Brett Porter
> Fix For: 2.0.x
>
>
> the cache in the project builder is a simple map. This is usually fine for
> Maven, but in long lived processes (Continuum, MRM, and I imagine the IDE
> plugins as it gets used more) it can chew up quite some memory.
> I'd suggest we make it configurable:
> - can turn it on or off using plexus configuration
> - can limit its size using plexus configuration
> - can change other options, such as adding expiry ages to items regardless of
> size
> Rather than implementing something in the project builder itself, I suggest
> having a cache plexus component that does everything we need it to (this
> could be reused in the webapps as well). I'm not sure of any existing caching
> solutions (I know OSCache has a general Java cache but don't know how
> suitable it is). One alterantive might be to round out commons-cache with
> some features and plexus descriptors.
