Java 报错 BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version

好吧，好久不写 Java 程序，今天用 gradle init 了一个项目运行就报错了

Java 报错 BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version

终极原因如下

我们的 gradle 7.5.x 并不适配 Java19，如果要玩 Java19 则需要 7.6.x 或者降低 Java 版本

我选择了降低 Java 版本，操作如下

Then, in IDEA:
Settings -> Build, Execution, Deployment -> Build Tools -> Gradle -> Gradle JVM, 选择: 1.8 version 1.8.0_292 代替 org.grade.java.home;

分析过程

然后赶紧用 java --version 看了下，没啥问题

openjdk 19 2022-09-20
OpenJDK Runtime Environment Homebrew (build 19)
OpenJDK 64-Bit Server VM Homebrew (build 19, mixed mode, sharing)

但是用 /usr/libexec/java_home -V 看了下，问题就大了

Matching Java Virtual Machines (4):
    19 (x86_64) "Homebrew" - "OpenJDK 19" /usr/local/Cellar/openjdk/19/libexec/openjdk.jdk/Contents/Home
    11.0.16.1 (x86_64) "Microsoft Build of OpenJDK" - "Microsoft Build of OpenJDK 11" /Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home
    1.8.202.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_302 (x86_64) "Eclipse Temurin" - "Eclipse Temurin 8" /Library/Java/JavaVirtualMachines/temurin-8.jdk/Contents/Home
/usr/local/Cellar/openjdk/19/libexec/openjdk.jdk/Contents/Home

我...怎么多了这么多版本啊。。。。

然后又看了下 gradle --version 的版本

------------------------------------------------------------
Gradle 7.5.1
------------------------------------------------------------

Build time:   2022-08-05 21:17:56 UTC
Revision:     d1daa0cbf1a0103000b71484e1dbfe096e095918

Kotlin:       1.6.21
Groovy:       3.0.10
Ant:          Apache Ant(TM) version 1.10.11 compiled on July 10 2021
JVM:          19 (Homebrew 19)
OS:           Mac OS X 12.6 x86_64

其实，用 Idea 编辑器打开项目，他会提示说

JDK 19 isn't compatible with Gradle 7.5.1. Please fix JAVA_HOME environment variable.

一句话：

我们的 gradle 7.5.x 并不适配 Java19，如果要玩 Java19 则需要 7.6.x

或者降低 Java 版本
