Question

我正在尝试将旧的maven / eclipse项目转换为pur maven项目，但更难的部分是转换此项目的tomcat启动配置。

为此，我使用tomcat7-maven-plugin：



<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <!-- On prend la version 2.1 pour avoir la dépendance Tomcat en version 7.0.37 -->
    <version>2.1</version>
    <!-- Test d&#795;’exclusion -->
    <!--<dependencies>-->
    <!--<dependency>-->
        <!--<groupId>org.apache.tomcat.maven</groupId>-->
        <!--<artifactId>tomcat7-maven-plugin</artifactId>-->
        <!--<version>2.1</version>-->
        <!--<exclusions>-->
        <!--<exclusion>-->
            <!--<groupId>org.slf4j</groupId>-->
            <!--<artifactId>jcl-over-slf4j</artifactId>-->
        <!--</exclusion>-->
        <!--</exclusions>-->
    <!--</dependency>-->
    <!--</dependencies>-->

当我执行命令行«mvn tomcat7：run»时出现此错误

我理解错误，2 lib互相打电话。所以我试图从WEB / lib中删除«slf4j-jcl.jar»并且没有出现错误。但是这种手动解决方法是不可接受的。使用«-e -X»选项我从maven插件中看到了«jcl-over-slf4j.jar»。

我的目标是从tomcat启动中排除这个«jcl-over-slf4j.jar»，但我不知道如何。帮助欢迎...或任何解决此问题的想法。

Maven Tomcat7插件“在类路径上检测到jcl-over-slf4j.jar和slf4j-jcl.jar”
