Im developing a URCap and using an external .jar library (moka7). The project compiles but when I charge it to the PolyScope the URCap shows with a “!” sign and wont work. The .jar is uploaded to the resources file.
I am not able to find out which are the values for groupId, artifactId or the version of my .jar.
Maybe it is because it originaly was a project that I got exported as a .jar to work with it as a library.
You can open the .jar like a .zip file and, if it was a maven project, you could extract that information from the pom.xml.
I haven´t tested the case of importing a non maven project. But that seems a general java problem so you could search in sites like StackOverflow for more answers.
