JAVA_HOME should point to a JDK not a JRE ( but it does )

Question

When I try to do a mvn clean install i get the following message:

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE

But when I do echo $JAVA_HOME , I get the following output: /usr/java/openjdk/jdk-16

Which means that JAVA_HOME is pointing to a JDK. I don't get the error.

My $PATH variable contains the jdk too:

echo $PATH returns echo $PATH /opt/maven/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/user/bin:/usr/java/openjdk/jdk-16/bin

Any help would be appreciated

Check the case sensitivity in your JAVA_HOME definition and also check whether $JAVA_HOME/bin/java.exe is executable in the current shell
