I received an error when attempting to build ACE from trunk: [ERROR] Failed to execute goal on project ace-repository-impl: Could not resolve dependencies for project org.apache.ace:ace-repository-impl:bundle:0.8.0-SNAPSH OT: Failure to find org.apache.felix:org.apache.felix.dependencymanager:jar:3.0. 0-SNAPSHOT in http://repository.apache.org/snapshots was cached in the local rep ository, resolution will not be reattempted until the update interval of apache. snapshots has elapsed or updates are forced -> [Help 1]
I pulled the latest felix from svn, locally built, and resumed the ACE build - all was good (dependencymanager was in my local repo at that point).
