I cannot reproduce this issue on a recent windows machine.

Make sure that you installed a JDK (at least JDK8 is required, a JRE is not sufficient) and that this is reachable from cygwin:

javac -version

Please try from scratch and make sure you use the stable 1.0 branch:

git checkout 1.0

and then run this:

./graphhopper.sh -a import -i europe_germany_berlin.pbf

If this still fails run the following manually and report the output:

mvn clean install
