I use Java + Robot Framework to test micro services. So I have created a several test projects for each service. For testing I create a few java classes with keywords to work with HTTP and JSON on low level. I separated these classes into a library which I plan to add to test project as maven dependency.
Also I want to add common keywords into robot-file to this external library.
But the problem is I cannot import those robot-files in my tests.
Please pay attention that first picture is external project, and second picture is project with tests.
Does anyone faced with such problem and if so which decision have you come up with?
