A problem occurred configuring root project 'MyApplication2'.
> Could not resolve all files for configuration ':classpath'.
> Could not resolve com.android.tools.build:gradle:7.4.2.
Required by:
project : > com.android.application:com.android.application.gradle.plugin:7.4.2
project : > com.android.library:com.android.library.gradle.plugin:7.4.2
> No matching variant of com.android.tools.build:gradle:7.4.2 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:7.4.2 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:7.4.2 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:7.4.2 declares a runtime of a library, packaged as a jar, and its dependencies declared externally:

昨天用老版本的Android Studio 新建了一个Kotlin项目，. 之类的提示没有，应该是环境问题，就升级了Android Studio到最新的电鳗版本，新建kotlin项目就报上述错误。
搜索了一圈，原来是gradle插件7.4.2版本比较新，需要Java11，以前配置的是Java8，修改下配置就可以了，以mac电脑为例，操作如下：
1、左上角 File ------- Project Structure, 如图：
2、SDK Location ----------- Gradle Settings ，如图：
3、Gradle JDK， 选择11的，点击OK , 如图：
4、Settings.gradle文件里，配置一些仓库地址，如图：
代码如下：
pluginManagement {
repositories {
maven { url 'https://maven.aliyun.com/repository/releases' }
maven { url 'https://maven.aliyun.com/repository/public' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
maven { url "https://www.jitpack.io" }
google()
mavenCentral()
gradlePluginPortal()
jcenter()
}
}
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
maven { url 'https://maven.aliyun.com/repository/releases' }
maven { url 'https://maven.aliyun.com/repository/public' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
maven { url "https://www.jitpack.io" }
google()
mavenCentral()
jcenter()
}
}
rootProject.name = "MyApplication2"
include ':app'
5、点击同步按钮，下载相应的库，如图：
6、 等待下载完毕，可能需要几分钟到几十分钟，只要下载进度是对的，就OK，如图：
7、. 已经可以正常提示语法了
好了，又可以愉快的玩耍了。
