我已将xgboost jar文件添加到项目结构中的库和模块中。 （我已经成功地从源代码构建了jar文件，如文档中所述）。我似乎无法解决它的依赖。我已经尝试使用build sbt文件中包含的依赖项来运行它并将其取出（因为jar已经包含在库中，并且通过项目结构包含依赖项）。两者似乎都失败了。这是某种兼容性问题吗？我正在运行scala 2.11.8和spark 2.1.0。我的依赖项包含在以下序列中：
"ml.dmlc" %% "xgboost4j" % "0.7", "ml.dmlc" %% "xgboost4j-spark" % "0.7"
我似乎错过了一些东西，但我不确定是什么。有什么想法吗？
我尝试按照建议发布jar，但是我收到以下错误：

答案 0 :(得分：0)
依赖项应该只有一个％。
"ml.dmlc" % "xgboost4j" % "0.7", "ml.dmlc" % "xgboost4j-spark" % "0.7"
