整合deeplearning4j與JHipster的Maven的pom.xml，越來越SLF4J綁定錯誤

我試圖deeplearning4j與JHipster pom.xml中集成了以下內容：整合deeplearning4j與JHipster的Maven的pom.xml，越來越SLF4J綁定錯誤

<dependency>

，我收到以下錯誤，而我運行\ mvnw：

，你可以看到我已經添加上deeplearning4j排除了，但我仍然得到SLF4J綁定衝突，不能用手指出了什麼問題。

你看過'mvnw dependency：tree'的輸出並搜索重複的依賴關係嗎？ –

是的，我做過了，但我仍然無法撥出重複的SLF4J。順便說一下，我使用JHipster 3.x和spring boot 1.3.5.RELEASE。 –

嗨，你可以在dl4j回購上提出問題嗎？ https://github.com/deeplearning4j/deeplearning4j/issues我認爲我們已經照顧了記錄器的依賴關係。謝謝！ –

我在eclipse中通過選擇依賴層次結構選項卡而不是'mvn dependency：tree -Dverbose -Dincludes = org.slf4j'來指出問題，並發現'org.neuroph'具有重複的'slf4j- nop'下面的pom.xml部分應該是：
