Use Clojure interfaces in a Java library project

Question

I would like to use some of the Clojure interfaces in a Java library project in several situations where it would be useful for my Java classes to implement them. In particular:

• clojure.lang.ISeq
• clojure.lang.IFn

Doing this would make my Java library much more user-friendly for Clojure-based users.

However I don't want to import the whole of clojure.jar as a dependency - since it is relatively large and my library is mainly targeted at Java users.

Is there a way to import and develop against the Clojure interfaces without bringing in the rest of Clojure?

Answer 1

Try it:

1. unpack the clojure jar
2. put only the .class you need into a directory named LightweightClojure
3. run you test appli (test + lib + LightweightClojure)
4. goto 2 until it works
5. zip the LightweightClojure directory into LightweightClojure.jar

如果你使用的是Maven，你可以使用Maven Shade Plugin的minim-jar配置。
