Hello again my friends that time i have this problem can anyone solve what i must do?

 

compile:
    [javac] C:\Workspace Bmxc\L2Jbmxc-Core\build.xml:47: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

BUILD FAILED
C:\Workspace Bmxc \L2Jbmxc-Core\build.xml:47: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program Files\Java\jre1.8.0_231"

You must have JDK installed and set as an compiler.

Prefereneces - Java - Installer JREs - add new standard VM, point it to jdk - select it, apply and close.
