Mac os Big Sur在此环境中没有提供编译器。也许您运行的是JRE而不是JDK？

Answer 1

我遇到了和你一样的问题。
这个解决方案（构建失败运行“mvn clean install”。我刚刚升级了Big Sur）是删除无用的JRE。
我的是给mvn shell一个正确的java_home。

当我运行命令/usr/libexec/java_home-v时

我可以看到2个虚拟机

MacBook-Pro:bin charles$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.251.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_251 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

if [ -z "$JAVA_HOME" ] && [ -x "/usr/libexec/java_home" ]; then
    #
    # Apple JDKs
    #
    export JAVA_HOME=`/usr/libexec/java_home`
fi

if [ -z "$JAVA_HOME" ] && [ -x "/usr/libexec/java_home" ]; then
    #
    # Apple JDKs
    #
    export JAVA_HOME=`/usr/libexec/java_home -v1.8.0`
fi

然后，它起作用了。

MVN-version

在我更新mvn之前，我将看到

MacBook-Pro:~ charles$ mvn -version
