1.Minimum supported Gradle version is 4.1. Current version is 4.0.1
各方面的配置都是正确的,在terminal中调用命令gradle assemble，总是报这个错误，找不到原因
E:\direct\as\Bingo>gradle assemble
* Where:
Build file 'E:\direct\as\Bingo\app\build.gradle' line: 1
* What went wrong:
A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.android.application']
> Minimum supported Gradle version is 4.1. Current version is 4.0.1. If using the gradle wrapper, try editing the distributionUrl in E:\direct\as\Bingo\gradle\wrapper\gradle-wrapper.properties to gradle-4.1-all.zip
最后试了一下
E:\direct\as\Bingo>gradle -version

原来是因为配置了环境变量（windows），所以，以后还是不要配置gradle的环境变量了，用项目根目录底下的gradlew命令就好
