找到不支持的Gradle DSL方法：“排除（）”

Question

如果：

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
    }
}

我收到此错误消息：

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

但这是可行的：

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'
}

试图了解原因，请澄清！

Answer 1

使用

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

所以用额外的括号。
