Unsupported Gradle DSL method found: 'exclude()'

Question

If:

dependencies {
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'de.keyboardsurfer.android.widget:crouton:1.8.3'
    compile 'de.greenrobot:eventbus:2.2.0'
    compile 'com.intellij:annotations:+@jar'
    compile 'com.jpardogo.googleprogressbar:library:1.0.0'

    compile project(':floatlabel')
    compile project(':Android-SwipeToDismiss')
    compile project(':Android-UndoBar') {
        exclude group: 'com.nineoldandroids', module: 'library' // without or without this one
    }
    compile project(':AndroidSlidingUpPanel:library') {
        exclude group: 'com.nineoldandroids', module: 'library' // without or without this one
    }
}

I receive this error message:

Gradle 'mProject' project refresh failed: Build script error, unsupported Gradle DSL method found: 'exclude()'!

But this works:

dependencies {
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'de.keyboardsurfer.android.widget:crouton:1.8.3'
    compile 'de.greenrobot:eventbus:2.2.0'
    compile 'com.intellij:annotations:+@jar'
    compile 'com.jpardogo.googleprogressbar:library:1.0.0'

    compile project(':floatlabel')
    compile project(':Android-SwipeToDismiss')
    compile project(':Android-UndoBar')
    compile project(':AndroidSlidingUpPanel:library')
}

configurations {
    all*.exclude group: 'com.nineoldandroids', module: 'library'
}

Trying to understand why, please clarify!

Answer 1

Use

compile (project(':Android-UndoBar')) {
        exclude group: 'com.nineoldandroids', module: 'library' // without or without this one
    }

So with extra parentheses.
