Maven依賴沖突問題及解決過程

更新時(shí)間：2026年04月29日 10:06:44 作者：秦JaccLink

文章主要討論Maven依賴沖突問題,及提供解決方法,首先描述了依賴沖突現(xiàn)象的nd導(dǎo)致類NoClassDefFoundError的情況；然后介紹了查找沖突包的方法,最后總結(jié)了Maven依賴管理的幾種策略,包括依賴調(diào)解、依賴排除和依賴范圍控制；強(qiáng)調(diào)了合理配置POM文件的重要性

引言

在開發(fā)過程中你的maven依賴有沖突，但是打包的Jar包照樣可以運(yùn)行只有使用到?jīng)_突包里的功能時(shí)會報(bào)依賴沖突錯誤比如：

1、找出沖突包

1.1 找到pom.xml文件

1.2 點(diǎn)擊Show Diagrams查看依賴圖

右擊pom.xml文件點(diǎn)擊--》Show Diagrams

如下圖會列出沖突包

2、移除沖突包

maven移除包中依賴

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>${poi.version}</version>
            <!-- 移除包中依賴 -->
            <exclusions>
                <exclusion>
                    <groupId>org.apache.poi</groupId>
                    <artifactId>poi</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
