类路径包含多个SLF4J绑定 - Spring boot

我有一个spring boot starter项目,我想从外部jar添加一个依赖项。我使用mvn install:install-file将jar添加到maven,然后将依赖项添加到我的pom.xml中。

添加依赖项并构建项目后,我收到以下错误:

Listening for transport dt_socket at address: 5005

我在stackoverflow上查看了有关此主题的所有问题,但没有解决我的问题。

在我的pom.xml中,我有了这个新的依赖:

<dependency>
    <groupId>com.hubtech</groupId>
    <artifactId>hubpipeline</artifactId>
    <version>1.0.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
        <exclusion>

            <artifactId>log4j-over-slf4j</artifactId>
        </exclusion>
        <exclusion>
            <groupId>com.typesafe.akka</groupId>
            <artifactId>akka-slf4j_2.11</artifactId>
        </exclusion>
        <exclusion>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </exclusion>
        <exclusion>
            <artifactId>slf4j-simple</artifactId>
            <groupId>org.slf4j</groupId>
        </exclusion>
    </exclusions>
</dependency>

我想从新添加的jar中排除冲突的依赖项。 但我做的任何事情都不会改变错误。

我的项目是使用jhipster生成的,并使用LogBack进行日志记录。
