我在 Windows 2012 服务器上使用 PowerShell，我从 System32 中删除了所有 java 命令，重新安装了 jdk，将 JAVA_HOME 和 Path 设置为指向新安装。而且我仍然收到以下错误：
java : The term 'java' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
