> Key: MOJO-1118
> URL: http://jira.codehaus.org/browse/MOJO-1118
> Project: Mojo
> Issue Type: Bug
> Components: dashboard
> Environment: Maven version: 2.0.9
> Java version: 1.6.0_02
> OS name: "linux" version: "2.6.21.7-3.fc8" arch: "i386" Family: "unix"

> For all projects I have tried I get the error "Invalid class loader
> hierarchy. You have more than one version of
> 'org.apache.commons.logging.Log' visible, which is not allowed.". (See full
> stacktrace at the bottom.)
> I get the same error on projects that don't use commons-logging directly, but
> there is still a chance that other plugins depend on commons-logging.
> The plugin depends on commons-logging version 1.0.4. Could this dependency be
> upgraded to 1.1.1?
> Version 1.1.1 solves many of the problems people have with commons-logging.
> E.g. more dependencies are optional.
> Is it anything I can do to fix this error?
> (I have tried to lock down commons-logging in dependencyManagement, but that
> didn't seem to make any difference.)
