Error excluding transitive dependencies in Gradle build file

I have to exlude some dependencies from all modules of a multi module project. With Gradle 1.12 the following gradle build file worked:

subprojects {
    ...
    //blacklisted dependencies
    configurations {
        all*.exclude module: 'ojdbc14' //we use ojdbc6
        all*.exclude group: 'c3p0', module: 'c3p0' //newer versions use groupId: com.mchange
        all*.exclude module: 'oracledb' //we use ojdbc6
        ...
    }
    ...
}

After upgrading to gradle version 2.1 i got error:

You can't change configuration 'providedCompileScope' because it is already resolved!

How to define exclusions now with the newer Gradle?

Exclusions are still specified in the same way. Gradle is just telling you about a problem with your build that it wasn't telling you about before, namely that exclusions can only be declared before a configuration gets resolved. Probably there is some custom code that iterates over configurations.providedCompileScope (or a derived configuration) and mistakenly does so in the configuration phase (i.e. during evaluation of the build scripts), rather than in the execution phase (e.g. inside a task action). This snippet (and the resulting --stacktrace) may help to locate the problematic code:

configurations.providedCompileScope.incoming.beforeResolve { 
    println new Exception("resolved here") 
}

EDIT: If you have something like the following in one of your build scripts:

idea.module {
    scopes.PROVIDED.plus += configurations.providedCompileScope
}

Change it to:

idea.module {
    scopes.PROVIDED.plus += [configurations.providedCompileScope]
}

This is necessary due to a change of behavior in the Groovy version used by Gradle 2.x.

Normally, I'd exclude transitive dependencies by specifying 

dependencies {
    myConfiguration('group:module:version') { transitive = false }
}

For more fine grained control over versions etc, have a look at ResolutionStrategy
