android – 资源条目ic_launcher已经定义

https://github.com/daimajia/AndroidImageSlider

当我把它放在我的gradle文件中时它会显示这些错误

ic_launcher已定义！
可能是什么错误？
我试图将构建工具更改为19.1.0,但我不认为这是一个问题？

这是我的build.gradle代码

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.daimajia.slider:library:1.0.1@aar'
    compile filetree(dir: 'libs',include: ['*.jar'])
}
