在pom编译后添加了不同版本的Maven: slf4 jar, war因此得到版本冲突错误



我的诗歌出了问题。即使我没有添加任何依赖，在战争中我得到:1. slf4j-api-1.5.11.jar2. slf4j-api-1.6.1.jar3.slf4j-log4j12-1.6.1.jar

问题:由于这个我的战争不能在服务器上运行，并得到关于冲突的错误。我需要解决这个问题。

手动解决方案:我手动从war中删除slf4j-api-1.5.11.jar，它开始在服务器上运行。

你能帮我避免这种手动解决方案吗?我的pom是它自己处理的。我也用过排斥，但没有用。

期待您的帮助

您可以使用依赖管理来确保每个slf4j依赖都是对齐的。

<dependencyManagement>
    <dependencies>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.12</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-IMPL-THAT-YOU-WANT</artifactId>
        <version>1.7.12</version>
    </dependency>
    </dependencies>
</dependencyManagement>

要知道哪个依赖需要并导入slf4j，您可以使用:

mvn dependency:tree -Dverbose

虽然YMomb的答案应该可以工作(而且很简单)，但您也可以显式地从依赖项中排除传递依赖项。

查找包含哪些依赖项。Slf4j作为传递依赖项，运行

mvn依赖:tree -Dincludes=org.slf4j:*

这将给你类似的东西，(至少它给了我从上面你的依赖)

[INFO] - org.quartz-scheduler:quartz:jar:2.1.7:compile [INFO]
org.slf4j: slf4j-api: jar: 1.6.1:编译

表示'quartz'有它，排除org。

您可以对包含slf4j的所有依赖项执行此操作。然后可以定义所需的slf4j版本并使用它

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.6.5</version>
</dependency>
