编译失败

你好，我在用Gradle添加该库时，编译不能通过，错误信息：

Error:Execution failed for task ':app:dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    D:\android\sdk\build-tools\21.0.2\dx.bat --dex --no-optimize --output D:\Android\app\build\intermediates\dex\debug --input-list=D:\Android\app\build\intermediates\tmp\dex\debug\inputList.txt
Error Code:

Output:

搜索后，应该是包重复了(应该是v4包)，我依赖的包:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:21.0.2'
    compile 'com.jakewharton:butterknife:6.0.0'
    compile 'com.google.code.gson:gson:2.3.1'
    compile 'de.greenrobot:eventbus:2.4.0'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3'
    compile 'it.sephiroth.android.library.imagezoom:imagezoom:+'
}
libs目录下是 ActiveAndroid和Volley的2个包

谢谢。

嗯，现在 support v4 包有冲突，暂没时间解决，可 clone 源代码自己编译

好的，谢谢。
