[zeromq-dev] ZeroMQ Java Binding install -- issues & solution

I’ve just grabbed the latest version and indeed it’s weird what is happening.

make creates a jar file inside src/main/c++/zmq.jar, which has a wrong folder hierarchy, like you show, with a ../java.

but if you ignore that file and run mvn clean -Dmaven.test.skip, then there is a correct jar inside target/jzmq4-4.0.0-SNAPSHOT.jar

The test.skip is because one of the tests if failing for me.

I have no time right now but if no one else fixes this, I’ll try to help tomorrow or during the week.
