從GitHub上下載下傳一個項目，導入Android studio之後報錯。報錯内容如下：
Error:There were multiple failures while executing work items
Error:Execution failed for task ':app:mergeDebugResources'.
> There were multiple failures while executing work items

報錯的截圖如下：
這個bug解決起來也比較簡單，在你的app的build.gradle的defaultConfig中添加如下的代碼就可以了：
defaultConfig{
vectorDrawables.useSupportLibrary = true
}
添加完 vectorDrawables.useSupportLibrary = true這行代碼之後，gradle一下就可以了。
