How to compile graphhopper project to use in map-matching?

Hi,

This is a newbie question and possibly related with java/maven, not with graphhopper.

I’m using map-matching project. However I want to modify some files in the graphhoper project (currently com/graphhopper/util/InstructionList.java file). Is there an easy way to configure the projects so that map-matching uses the classes (or jars) generated by graphhopper for core and web packages instead of downloading its recent build from web?

I know a little bit of java but I’m a stranger to the current build tools.

Thanks

Which IDE are you using? Even without any IDE support you can normally build the jar file of core and web (mvn clean install -DskipTests=true), this will also deploy the jars into your local repository (<home>/.m2/repository) and the changes should be picked up if you refer in the map matching project to the correct version (it will use the packaged jars from the local repository).

It worked. Thanks. I had no idea how maven works.
