剛剛把專案gradle升級到3.2.1後項目報了個錯：

Android resource compilation failed
Output:  /Users/gaoxingfei/shidonghui/shidonghui_Android/app/build/intermediates/incremental/mergeAnzhiDebugResources/merged.dir/values/values.xml:1817: error: duplicate value for resource 'attr/content' with config ''.

意思是有資源id重複了，點選藍色區域後跳轉到build資料夾下的values.xml裡邊，可以直接定位到有問題的行，

這裡是我的自定義屬性“content”跟別的地方重複了，換個欄位名就沒問題了
