无法使用joplin迁移Cassandra

我正在尝试使用为我的Cassandra数据库运行迁移。 但是，当我运行lein migrate dev时，会出现以下异常：

Migrating #joplin.cassandra.database.CassandraDatabase{:hosts [127.0.0.1:9042], :keyspace test} 

Exception in thread "main" java.lang.IllegalArgumentException: No matching ctor found for class com.datastax.driver.core.policies.DCAwareRoundRobinPolicy, compiling:(clojurewerkz/cassaforte/policies.clj:38:3)

我认为问题可能在于我的迁移，但我不确定我做错了什么

project.clj

(defproject app "0.1.0"
:dependencies [[org.clojure/clojure "1.8.0"]
             [clojurewerkz/cassaforte "3.0.0-alpha1"]

             [joplin.core "0.3.10"]
             [joplin.cassandra "0.3.10"]

             [cc.qbits/alia "4.2.3"]
             [cc.qbits/hayt "4.0.2"]
             ]

        "create" ["run" "-m" "joplin.alias/create" "config.edn"]}
)

config.edn

迁移者

(ns migrators.20180717174605-test
  (:use [joplin.cassandra.database])
  (:require [clojurewerkz.cassaforte.client :as client]
[clojurewerkz.cassaforte.cql :refer :all]))

(defn up [db]
  (let [conn (client/connect (:hosts db))]
    (create-keyspace conn "test")))

(defn down [db]
  (let [conn (client/connect (:hosts db))]
    (drop-keyspace conn "test")))

问题在于cc.qbits/alia依赖于Cassandra Java驱动程序3.5.0，而版本为3.0.0-alpha1的cassaforte依赖于旧版本2.1.6。看起来alia的依赖项隐藏了cassafortes，在drivers 3.x中找不到DCAware策略的构造函数，使用的是构造函数而不是直接构造函数

---

您可以从存储库安装cassaforte-它是为了与3.x驱动程序一起使用。

对于joplin 0.3.9+请参阅更改文档，使用alia&hayt代替cassaforte。

您能检查您的类路径吗？是否包括datastax java驱动程序？
