[1.3] Overriding core Play dependency c3p0 v0.9.1.2 with a more recent version

[tazmaniac]

I'd like to update c3p0 to a more recent version. I updated the dependencies in my application with "- com.mchange -> c3p0 0.9.5-pre6" but this does not replace the original version 0.9.1.2 because they have a different groupIds so both versions exist in the classpath. Is it possible to 'exclude' the original core framework c3p0 dependency?

thx

Hi tazmaniac

I don't know if it's possible with pure Play!, but it's very easy with Play! + Maven + Maven plugin for Play! Framework (http://code.google.com/p/maven-play-plugin/)
Are you interested?

Greetings

Hi,

looking trough the code of YamlParser.java it seems to have an exclude options (can't find it in the docs though) - you could experiment with it.

Hi Robert,

I followed the 'exclude' pattern here, http://www.playframework.com/documentation/1.2.7/dependency#Transitivedependencies and applied it like so:

require:

    - play 1.3.0:

        exclude:

            - c3p0 -> c3p0 0.9.1.2

When I ran dependencies with "--verbose" it appeared to successfully exclude that dependency but what confused me was when I ran eclipsify it did not remove that library from the classpath. Possibly eclipsify does not follow the dependency list and just scoops up all of the jars from the framework lib directory.

rgds,

Chris
