Classpath conflict: org.clojure/clojure version 1.7.0 already loaded, NOT loading version 1.8.0
问题 When copying a build.boot file from an old project to a new one I got the following error and found nothing on Google: Classpath conflict: org.clojure/clojure version 1.7.0 already loaded, NOT loading version 1.8.0 回答1: You should just include [org.clojure/clojure "1.8.0"] with the same version as boot environment variable BOOT_CLOJURE_VERSION=1.8.0 into build.boot dependencies list. Another way to get rid of this issues is to exclude clojure dependency from several dependencies in the list.
