There is include error with when I try include dependency carmine 2.15.1

fixed with moving dependency up

I'm also running into this problem. Can you clarify what you mean by moving dependency up?

[yayitswei]

I solved it by including

[commons-codec/commons-codec "1.10"]

in my dependencies.

Hi @yayitswei, @mprokopov, please see here for details on how to identify and resolve dependency conflicts in general. In your case you'll just want to look for commons-codec instead of encore.

Unfortunately this hassle is sometimes necessary since there's no inherently fool-proof way of resolving transitive dependency conflicts.

Say you're using the following two libraries:

1. Library A (which also uses library C version 1.1.0).
2. Library B (which also uses library C version 1.2.0).

There's a dependency conflict on library C; you're indirectly asking for two different versions. In many/most cases what you want is to resolve the conflict by manually instructing your dependency manager (Leiningen for example) to use the later version of library C.

That's not always the correct choice though, so it's not a decision that Leiningen and co. can make for you automatically.

That's why you need to check for and resolve conflicts yourself.

Hope that helps!
