一、报错信息

创建个新项目，运行直接报错，信息如下：

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:

二、错误分析

 有些问题是项目中的Gradle版本不是7.4.2，我们需要将build.gradle文件中改它为7.4.2。

plugins {id 'com.android.application' version '7.4.2' apply falseid 'com.android.library' version '7.4.2' apply falseid 'org.jetbrains.kotlin.android' version '1.8.0' apply false
}

这里明显不是，从报错信息中我们可以看到是Java 版本没跟上，需要将Java 8 改为 Java11。

解决方案：

OK->OK->Try Again 齐活。
