Sempre que rodo o ant jetty.run a build falha com a seguinte mensagem
compile: [javac] c:\leiloes\build.xml:41: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
BUILD FAILED c:\leiloes\build.xml:41: 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_251"
já tenho o Java JDK instalado no PC. Alguém poderia me ajudar?
