/bin is missed in JDK

I'm trying to install Maven on RH7 but I'm getting the error:

NB: JAVA_HOME should point to a JDK not a JRE

The thing is that I have Java is already installed and $JAVA_HOME is defined correctly (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64), but it has to be added to $PATH as $JAVA_HOME/bin and I don't have bin in $JAVA_HOME, the only directory I have there is jre.

Please help!

Solution

  • I don't have bin in $JAVA_HOME, the only directory I have there is jre.

    That almost certainly means you haven't actually got the JDK, just the jre, despite the folder name (hence the Maven error.)

    Try installing / extracting the full JDK somewhere else if necessary (either by adding an external RPM and grabbing it, or just downloading it manually if you want the simple approach), then point JAVA_HOME to that directory.
