Is someone has same problem? I dont have any idea about the problem.

Thanks in advance for help,

Could you try to run mvn clean compile -e in the graphhopper folder and report the results?

Cheers,
Robin

Thanks for your answer.

Is it possible my JAVA_HOME is set on the wrong directory :
JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-amd64" ?

If this path is your actual JAVA_HOME, then it should be correct. It is also a good idea to set the java home into your bin path. So if you run java -version and javac -version you should see the correct versions?

You could also try this.

Thanks a lot for your answer.
Java was set but javac didn’t. It solved my problem. Sorry for that newbie mistake.
