似乎环境没有问题。那么，导致构建失败的问题在哪里呢？

Answer 1

我在将Mac更新到Big Sur后也遇到了同样的问题！所以我设置了JAVA_HOME的env变量，现在一切都恢复正常了。打开终端并点击以下命令自行解决。

$ vim .bash_profile 
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

运行以下命令检查您的java_home:

/usr/libexec/java_home-V

Answer 2

我把Mac升级到Big Sur后，也面临着同样的问题！

BigSur出于某种原因添加了JRE path，并且优先级高于自己JDK。

这是我的解决方案：

第一：

/usr/libexec/java_home -V

那么也许你会得到:

Matching Java Virtual Machines (2):
    1.8.202.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_202 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

所以第二个是我们真正的JDK。只需在您的bash配置文件中编辑JAVA_HOME。

vim ~/.zshrc
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home"
source vim ~/.zshrc
echo $JAVA_HOME

然后它就会起作用！享受虫苏尔！

或者您可以通过此cmd重新安装jdk8:

brew tap adoptopenjdk/openjdk
brew cask install adoptopenjdk8

Answer 3

出于某种原因，BigSur添加了JRE路径，我卸载了JRE，因为我需要JDK(而不是JRE ),它工作了。

1. 转到 /Library/Internet插件。
2. 以root用户身份执行rm命令或使用sudo工具删除JavaAppletPlugin.plugin目录。
3. 转到 /Library/PreferencePanes.
4. 以root用户身份执行rm命令或使用sudo工具删除JavaControlPanel.prefpane。
