Upgrade from 2.x to 3.x: No such var: encore/simple-date-format when compiling #53

Trying to upgrade from 2.x to 3.x. When I try to compile my project (with lein compile) I'm getting a compilation error:

Exception in thread "main" java.lang.RuntimeException: 
No such var: encore/simple-date-format, compiling:(taoensso/timbre.clj:278:27)

Hi Dave, thanks for getting in touch!

Just checked and [com.taoensso/timbre "3.1.2"] seems okay. It's possible you've got a dependency conflict.

Two things to try:

lein deps :tree - you should have a [com.taoensso/encore "0.9.6"] dependency, or newer. If you don't (due to a conflict for example) - try add the dep directly to your project.clj.
lein clean to clean out your Lein target dir (it can cause strange problems sometimes).

Please ping me again with your lein deps :tree output if those don't help and I'll try track down the problem.

Cheers! :-)

Thanks for the tip on lein deps :tree. That shows the problem:

Possibly confusing dependencies found:
[com.taoensso/faraday "1.2.0" :exclusions [org.apache.httpcomponents/httpclient org.apache.httpcomponents/httpcore]] -> [com.taoensso/encore "0.9.2"]
 overrides
[com.taoensso/timbre "3.1.2" :exclusions [junit]] -> [com.taoensso/encore "0.9.6"]

I put an exclusion into the faraday dependency for com.taoensso/encore and it's compiling now.

Thanks again.
