最近引用Fresco，遇到了一堆引用报错导致编译不同过。下面是中文引导：

然后集成这些第3方库会引起：

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ':moffice:transformClassesWithJarMergingForDebug'.> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/annotation/DrawableRes.class

* Try:

         Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

         BUILD FAILED

其中annotation这个包多处引用：

解法：

利用终端：

gradlew ：{appname}:dependencies  会罗列出你所有的改project依赖

这些都是引用树，你需要找到冲突的包然后干掉他

_debugCompile -  ##Internal use, do not manually configure## 

\--- com.android.support:appcompat-v7:23.4.0

+--- com.android.support:animated-vector-drawable:23.4.0

|    \--- com.android.support:support-vector-drawable:23.4.0

|        \--- com.android.support:support-v4:23.4.0

|              \--- com.android.support:support-annotations:23.4.0

+--- com.android.support:support-v4:23.4.0 (*)

\--- com.android.support:support-vector-drawable:23.4.0 (*)

怎么改掉呢？

看这个：Gradle脚本分析{ http://www.open-open.com/lib/view/open1431391503529.html }

大致这样：

compile ('com.android.support:recyclerview-v7:23.4.0') {

                exclude group:'com.android.support'

}

希望能帮助到你
