access infinispan .class in Clojure

Question

I am trying to replicate a snippet of code from the Infinispan documentation in Clojure:

ConfigurationBuilder b = new ConfigurationBuilder();
b.persistence()
  .addStore(SoftIndexFileStoreConfigurationBuilder.class)
  .indexLocation("/tmp/sifs/testCache/index");
  .dataLocation("/tmp/sifs/testCache/data")

Here is my attempt:

(import '[org.infinispan.persistence.sifs.configuration.SoftIndexFileStoreConfigurationBuilder])
(import '[org.infinispan.configuration.cache ConfigurationBuilder])

(def b (ConfigurationBuilder.))

(.addStore (.persistence b)
           (class org.infinispan.persistence.sifs.configuration.SoftIndexFileStoreConfigurationBuilder))

;; java.lang.ClassNotFoundException: org.infinispan.persistence.sifs.configuration.SoftIndexFileStoreConfigurationBuilder

How do I get past this exception? This is the SIFS source

For your case, you should have in your dependencies:

:dependencies  ... others here ...
               [org.infinispan/infinispan-core "9.0.1.Final"]
               [org.infinispan/infinispan-persistence-soft-index "9.0.1.Final"]

Also, you are using import incorrectly. You can either do:

(import full.package.name.ClassNameHere)

or

(import [full.package.name ClassNameOne ClassNameTwo])

For your case, you should be doing:

(import org.infinispan.persistence.sifs.configuration.SoftIndexFileStoreConfigurationBuilder)

Note that unlike require, where a nil result means "everything's good," with import a nil return means "nothing was imported."
