遇到的错误1- android 编译错误::Extension with name 'kotlin' does not exist

在编译时，遇到了报错：

An exception occurred applying plugin request [id: 'kotlin-kapt']
> Failed to apply plugin 'kotlin-kapt'.
> Extension with name 'kotlin' does not exist. Currently registered extension names: [ext, defaultArtifacts, sourceSets, reporting, java, javaToolchains, buildOutputs, android, androidComponents, androidComponents_compat_by_type, kapt]

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.plugins.InvalidPluginException: An exception occurred applying plugin request [id: 'kotlin-kapt']

于是参考了大佬的这篇文章：https://www.cnblogs.com/caosq/p/15649060.html

得以解决。

plugins {
    id 'com.android.library'
    id 'kotlin-kapt'
    id 'kotlin-android'
}
把

 id 'kotlin-kapt'
 id 'kotlin-android'的位置互换就行了

改完之后：

plugins {
    id 'com.android.library'
    id 'kotlin-android'
    id 'kotlin-kapt'
}

运行成功。
