我尝试将 deeplearning4j 与 JHipster pom.xml 与以下内容集成：

<dependency>
        <groupId>org.deeplearning4j</groupId>
        <artifactId>deeplearning4j-core</artifactId>
        <version>0.8.0</version>
       <exclusions>
           <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            </exclusion>
            <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>log4j-over-slf4j</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
            <exclusion>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-classic</artifactId>
            </exclusion>
            <exclusion>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-access</artifactId>
            </exclusion>
    </exclusions>
</dependency>

我在运行 .\mvnw 时收到以下错误：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/william/.m2/repository      /org/slf4j/slf4j-nop/1.7.6/slf4j-nop-1.7.6.jar!/org/slf4j/impl/StaticLoggerBinder.class]

如您所见，我已经在 deeplearning4j 上添加了排除项，但我仍然遇到 SLF4J 绑定冲突，无法找出问题所在。

我通过选择 Dependency Hierarchy 选项卡而不是 'mvn dependency:tree -Dverbose -Dincludes=org.slf4j' 在 eclipse 中使用 m2eclipse 来找出问题，并发现 'org.neuroph' 有一个重复的 'slf4j-nop' 以下pom.xml 部分应该是：

        <dependency>
        <groupId>org.deeplearning4j</groupId>
        <artifactId>deeplearning4j-core</artifactId>
