Incompatible because this component declares an API of a component compatible with
Java 17 and the consumer needed a runtime of a component compatible with Java 11.

解决方案
Gradle 运行需要JVM，上述报错说是声明使用Java 17， Gradle在运行时使用了Java 11. 因为我本地默认的环境Java version 是 11， 所以需要设定gralde 运行时使用的 Java version.
- 如果使用的是命令行运行gralde command， 则需要添加gradle.properties 文件，里面设置Java home 参数
org.gradle.java.home=/Users/xxx/Library/Java/JavaVirtualMachines/corretto-17.0.6/Contents/Home
- 如果使用的是 IntelliJ IDEA 里的 Gradle plugin运行命令，则需要制定 Gradle plugin 运行时的JVM home.
