Eclipse jxmaps no valid license found

Question

I have imported jxmaps to eclipse. But I get the error when running the code (which i copied from online to test the import worked to ensure there wouldn't be an error within the code):

Exception in thread "main" java.lang.ExceptionInInitializerError
    at com.teamdev.jxmaps.internal.internal.ipc.m.a(SourceFile:44)
    at com.teamdev.jxmaps.internal.v.<init>(SourceFile:53)

    at StreetViewExample.main(StreetViewExample.java:43)
Caused by: java.lang.RuntimeException: JxMaps license check failed: No valid license found.

I assume this is the same process with all external libraries, but how do you resolve this issue?

This is where I imported the libraries if this helps.

Thanks in advance
