Falcon is the first project I have seen that is not directly a Maven project and that uses Guice. So I never had this problem.
The main problem ist hat Maven comes with some libs that are used in the versions that are in the maven installations lib directory. These always have priority over the versions sub-classloaders load. I tried several tricks, especially changing the type of the variable from LoadingCache to Cache und cast to LoadingCache wherever needed, but the JIT compiler of Java seems to detect the shortcut and replaces this with the right type :-( Currently I'm sort of stuck and I coudln't find a way to override the version of maven ... think I'll post a question tot he maven dev list. Perhaps they can help. Chris -----Ursprüngliche Nachricht----- Von: Alex Harui [mailto:aha...@adobe.com] Gesendet: Freitag, 3.

Seems like if Maven is using older versions of popular JARs they must have hit issues like this before? Are all Maven artifacts stuck to these older versions? -Alex On 10/3/14, 7:31 AM, "Christofer Dutz" <christofer.d...@c-ware.de> wrote: >Hi, > >so I think I'm almost finished with adding Falcon support to Flexmojos. >After being able to resolve all issues that I have come across, this >one seems to be a blocker :-( > >Falcon uses Guava ...
