Cannot Determine a Valid Java Home

The error cannot determine a valid java home occurs when the Java Home path is not correctly set. We must follow the steps to correctly set our Java Home to solve this issue.

Even after that, the same error occurs. Follow the steps below to solve this issue.

First, define a new variable JAVA_HOME and assign it the path of the Java installation directory.

JAVA_HOME =  C:\Program Files\Java\jdk-17.0.2

Now update the Path variable and add the bin directory.

%JAVA_HOME%\bin

Now add this to your Path variable; this can be done from environment variables.

Now you can check if it’s working or not; insert the following command in CMD or shell.

java -version

The output for this will be:
