Question

我正在Jenkins上部署应用程序，我得到了Multiple bindings error

我已经尝试过将排除项添加到我的pom中。然后我运行了maven dependency：tree 命令来跟踪是否有任何其他依赖项正在使用logback并且没有对它的引用。运行此命令logs后，这是我的日志。奇怪的是，在我的本地机器上，应用程序构建并成功启动。这是我最新的pom.xml：

    <module>my-first-module</module>
    <module>my-second-module</module>

我甚至尝试过愚蠢的事情，例如为每个pom中的每个依赖项添加排除项，但仍然没有变化。

           <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>ch.qos.logback</groupId>
                    <artifactId>logback-classic</artifactId>
                </exclusion>
            </exclusions>

我也试过了这个例外情况：

          <exclusions>
              <exclusion> 
                  <groupId>org.slf4j</groupId>
                  <artifactId>slf4j-log4j12</artifactId>
              </exclusion>
              <exclusion> 
                  <groupId>log4j</groupId>
                  <artifactId>log4j</artifactId>
              </exclusion>
          </exclusions>

即使那两个结合了。我不知道还有什么其他选择，如果有人有任何想法，我会很感激，谢谢。

还添加了此question的排除项，但仍然没有更改。

Answer 1

我遇到了同样的问题，但是当我添加 swagger-codegen-maven-plugin 时它开始发生，并且在制作 mvn dependency:tree 之后我发现它们还有 slf4j-simple-1.7.30.jar。然后我添加了排除：

<dependency>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-codegen-maven-plugin</artifactId>
    <version>2.3.1</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
        </exclusion>
    </exclusions>
</dependency>

类路径包含多个SLF4J绑定，即使有排除项也是如此
