MacOS下JDK/javac降级遇阻：从17.0.5转至1.8求助

设备配置 #

• MacOS Big Sur v11.6.8
• Java v1.8.0_351
• Javac v17.0.5
• Gradle v7.6
• Homebrew v3.6.16

执行/usr/libexec/java_home -V输出：

Matching Java Virtual Machines (4):
    17.0.5 (x86_64) "Oracle Corporation" - "Java SE 17.0.5" /Library/Java/JavaVirtualMachines/jdk-17.0.5.jdk/Contents/Home
    1.8.351.10 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_351 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_351.jdk/Contents/Home
    1.8.0_341 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_341.jdk/Contents/Home

尝试步骤及遇到的问题 #

1. 已通过sudo nano配置bash profile指向Java v1.8，但未生效
2. 执行sudo mv jdk1.8.0_351.jdk ~/Desktop/时提示错误：mv: rename jdk1.8.0_351.jdk to /Users/sahil/Desktop/jdk1.8.0_351.jdk: No such file or directory
3. 执行echo $JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_351.jdk/Contents/Home时提示权限错误：zsh: permission denied: /Library/Java/JavaVirtualMachines/jdk1.8.0_351.jdk/Contents/Home
4. 改用bash_file代替zshenv执行类似命令，仍出现相同权限错误

恳请各位提供解决思路，谢谢！
