• Where did JAVA_HOME come from? What is its value? – Tim Roberts Commented Jan 9 at 18:31
• /Library/Java/JavaVirtualMachines/jdk-21.jdk/Contents/Home\bin\java. It seems like your current path is a mix of / and \. Try updating it in a way that use only one of these. – Reza Farjam Commented Jan 9 at 18:46
• Tried multiple times, didn’t work. If possible, can you share the command? – Syed Mishkatul Haque Commented Jan 9 at 19:15

try updating JAVA_HOME variable

• Open windows search and write Environment Variables
• Click on Edit the system environment variables
• Click the Environment Variables button on bottom
• Under System Variables or User variables search for JAVA_HOME.
• if exists update it with your JDK absolute path (just open the folder and click on top to get absolute path)
• if doesn't exists create a new variable and call it JAVA_HOME and then just enter your JDK absolute path in variable value
• click OK and apply changes

or you can just enter a command

setx /m JAVA_HOME [your JDK absolute path]

here a example on how to get you jdk absolute path screenshot
