scala 中与 xgboost 库的未解决依赖关系

Question

我已经在我的项目结构中的库和模块中添加了我的 xgboost jar 文件。（如文档中所述，我从源代码成功构建了 jar 文件）。我似乎无法解决它的依赖关系。我尝试运行它与包含在构建 sbt 文件中的依赖项一起取出（因为 jars 已经通过项目结构包含在库和依赖项中）。两者似乎都失败了。这是某种兼容性问题吗？我是运行ning scala 2.11.8 和 spark 2.1.0。我的依赖项包含在如下序列中：

"ml.dmlc" %% "xgboost4j" % "0.7", "ml.dmlc" %% "xgboost4j-spark" % "0.7"

我似乎遗漏了什么，但我不确定是什么。有什么想法吗？

我尝试按照建议发布 jar，但出现以下错误：

Answer 1

依赖项应该只有百分之一。

"ml.dmlc" % "xgboost4j" % "0.7", "ml.dmlc" % "xgboost4j-spark" % "0.7"
