I removed my old Eclipse, and installed the latest one – Mars (Version: Mars.1 Release (4.5.1)).
You are right that, with the latest Eclipse, all the issues described in the guideline are gone.
I also installed the latest Maven as you do (v3.3.9), and the latest JDK 8u73.
After that I import ‘algoquant’ project (not ‘algoquant-core’) , nothing changed (of course, you need to put your license file in ‘algoquant/license’ folder), right-click the project, then choose “Run As” > “Maven build” (which I configured it as “clean install”). The build works like a charm!
Could you try again please?
Or please share more information here if you have some other configurations.
