今天新建了一个工程，报了如下错误
A problem occurred configuring root project 'My Application'.
> Could not resolve all files for configuration ':classpath'.
> Could not resolve com.android.tools.build:gradle:7.4.1.
Required by:
project : > com.android.application:com.android.application.gradle.plugin:7.4.1
project : > com.android.library:com.android.library.gradle.plugin:7.4.1
> No matching variant of com.android.tools.build:gradle:7.4.1 was found. The consumer was configured to find a runtime of a library compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '7.5' but:
- Variant 'apiElements' capability com.android.tools.build:gradle:7.4.1 declares a library, packaged as a jar, and its dependencies declared externally:
- Incompatible because this component declares an API of a component compatible with Java 11 and the consumer needed a runtime of a component compatible with Java 8
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '7.5')
- Variant 'javadocElements' capability com.android.tools.build:gradle:7.4.1 declares a runtime of a component, and its dependencies declared externally:
- Incompatible because this component declares documentation and the consumer needed a library
- Other compatible attributes:
- Doesn't say anything about its target Java version (required compatibility with Java 8)
- Doesn't say anything about its elements (required them packaged as a jar)
- Doesn't say anything about org.gradle.plugin.api-version (required '7.5')
- Variant 'runtimeElements' capability com.android.tools.build:gradle:7.4.1 declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
- Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '7.5')
- Variant 'sourcesElements' capability com.android.tools.build:gradle:7.4.1 declares a runtime of a component, and its dependencies declared externally:
- Incompatible because this component declares documentation and the consumer needed a library

- Doesn't say anything about its target Java version (required compatibility with Java 8)
- Doesn't say anything about its elements (required them packaged as a jar)
- Doesn't say anything about org.gradle.plugin.api-version (required '7.5')
这个原因是最新的AndroidStudio 所用的gradle需要使用jdk11才能构建 ，因此要更改AndroidStudio的jdk版本
我的AndoirdStudio版本是
gradle版本用的是
解决方案如下，
打开如下页面。
File -> ProjectStructure -> Gradle Setting . -> Gradle JDK

文件加入google()
这里有个小提醒，尽量将google()放在jcenter()上面
这个问题基本是墙的问题，所以如果上面方法无效，可以试下下面的方法，一样是在项目的

文件加入一段代码

使用Flutter引入pub的时候经常遇到
