Maven依赖排除似乎不起作用 [英] Maven dependency exclusion doesn't seem to work

问题描述

我有一个Maven项目，具体取决于其他几个Maven项目.我在项目中使用Spring 3.1.1，而从属项目具有3.0.6.我试图在部署时排除Spring 3.0.6，因为两者都不可能.为此，我在POM中添加了一个明确的排除项，但是由于某些原因，当我启动Tomcat服务器时，我仍然在WEB-INF/lib文件夹中看到旧版本的spring core jars.有人可以指出我要去哪里.这是我的pom.xml:

I have a Maven project depending on couple other Maven projects. I am using Spring 3.1.1 in my project and dependent projects have 3.0.6. I am trying to exclude Spring 3.0.6 when deploying since having both isn't possible. I have added an explicit exclusion in my POM for that but for some reason I still see old version of spring core jars in the WEB-INF/lib folder when I start the Tomcat server. Can someone point me out where I am going wrong. Here is my pom.xml:

<project>
   ....
<properties>
    <org.springframework-version>3.1.1.RELEASE</org.springframework-version>
</properties>
<dependency> 
        <groupId>com.test.abc</groupId>

        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-core</artifactId>
             </exclusion>
        </exclusions>            
      </dependency>

        ....    
       </project>

推荐答案

您的依赖类型是war，因此这里没有解决的问题. Maven将战争内容覆盖在您的项目上.

Your dependency type is war so there is no resolution happening here. Maven overlays the war contents over your project.

当战争发布到资源库时，工件将在WEB-INF lib文件夹中包含依赖库.覆盖期间，它不会将lib文件夹与任何静态资源区别开，除非您告诉它以不同的方式排除它.检查"overlay"属性

When the war is published to repository, the artifact will contain dependent libraries in WEB-INF lib folder. During overlay it does not treat lib folder any different from any static resource unless you tell it to exclude in different way.Check 'overlay' property here
