I am trying to use in my Scala project Java library which is on Maven Central. While resolving this dependency, SBT appends Scala version to the repository url which obviously does not exist in such a format. Can I somehow disable appending Scala version for this specific artifact?
Yes, use % instead of %% before the artifact specifier for your dependency. The %% notation indicates that the library is dependent on the Scala runtime version, yours is not.
