ionic打包報錯Execution failed for task ':compileDebugJavaWithJavac'.

添加ionic插件cordova-plugin-file可能會遇到以下報錯

• 提示信息

:processDebugResources
:generateDebugSources
:compileDebugJava

若是你在ionic cordova platform add android時，有注意到cordova-plugin-file是須要cordova-android版本大於等於6.3.0

• 解決方案

因此只須要運行命令
ionic cordova platform remove android
ionic cordova platform add android@6.3.0
這樣就在運行ionic build就能打包成功了
