android gradle 和gradle plugin
1、安装完AS3.5.2创建完项目一运行，报了如下错误
Error:Could not find com.android.tools.build:gradle:4.1. Searched in
the following locations:
file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.pom
file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.jar
https://repo1.maven.org/maven2/com/android/tools/build/gradle/4.1/gradle-4.1.pom
https://repo1.maven.org/maven2/com/android/tools/build/gradle/4.1/gradle-4.1.jar
https://littlefogcat.top/example/com/android/tools/build/gradle/4.1
问题分析：
首先想到的是去看看我的grid : File =>Settings =>gradle
发现我gradle的是存在的
那么去看看项目的gridle版本：File=>project structure =>project 查看，发现我的
Android Gradle Plugin Version 版本和我的插件版本都是4.1
按理说因该没问题的啊，
但是实际是这样的么？
回到问题本身，再去看看错误提示信息没有找到C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/4.1/gradle-4.1.jar
再去他给的下载地址去看看，发现目前为止最新版本的gradle是2.3.0
好吧，那就把我的gradle plugin版本改为2.3.0
问题解决：
把我的gradle plugin版本改为2.3.0
2、新问题来了：

问题分析：gradle版本过低，不支持c....需要升级到3.0以上的版本
