Maven 指令 mvn:dependency:tree 查看依赖
一、指令指导文档:
官方文档:https://maven.apache.org/plugins/maven-dependency-plugin/tree-mojo.html
https://maven.apache.org/plugins/maven-dependency-plugin/examples/filtering-the-dependency-tree.html
二、常用参数详解
-
includes
类型:String
描述:显示包含依赖的jar包。
格式:[groupId]:[artifactId]:[type]:[version]
,支持通配符*。例如,org.apache.*
将匹配groupid 以org.apache.
开头的所有内容;:::*-SNAPSHOT
匹配所有jar。 -
excludes
类型:String
描述:显示不包含依赖的jar包。
格式:[groupId]:[artifactId]:[type]:[version]
,支持通配符* -
appendOutput
类型:boolean
描述:是否将输出内容追加到文件或覆盖它。
默认值:false
-
outputEncoding
类型:String
描述:无
默认值:${project.reporting.outputEncoding}
-
outputFile
类型:File
描述:如果指定,此参数将将依赖关系树写入指定的路径,而不是写入控制台。 -
outputType
类型:String
描述:如果指定,此参数将使用指定格式写入依赖关系树。当前支持的格式有:(text
默认)dot
、graphml
和tgf
。这些附加格式可以绘制到图像文件中。
默认值:text
。 -
verbose
类型:boolean
描述:查看冲突和重复的具体情况
默认值:false
。
三、一般常用的命令
-
查看项目依赖:
mvn dependency:analyze
-
查看项目直接和传递依赖:
mvn dependency:tree
-
冲突和重复的具体情况,用verbose参数
mvn dependency:tree -Dverbose
-
查看依赖树中包含某个groupId和artifactId的依赖链(注意-Dincludes后面是等于号)
mvn dependency:tree -Dincludes=com.alibaba:fastjson
-
查看依赖树中包含某个artifactId的依赖链(artifactId前面加上冒号)
mvn dependency:tree -Dincludes=:fastjson
-
查看依赖树中包含某个groupId的依赖链(-Dincludes后面跟上groupId)
mvn dependency:tree -Dincludes=com.alibaba
-
查看maven构建时有效的pom:
mvn help:effective-pom
-
重定向至文本文件
mvn dependency:tree -D outputFile=dependency_tree.txt
mvn dependency:tree -D outputFile=dependency_tree.txt -D outputType=dot
-
查看冲突和重复的具体情况,用verbose参数
mvn dependency:tree -Dverbose
“+-”符号表示该包后面还有其它依赖包,“-”表示该包后面不再依赖其它jar包。每个层级结尾处用 - 标记
以下面springboot项目为例,运行上述命令显示的结果:
https://gitee.com/tiankong0310/springboot-weixin-alipay?_from=gitee_search
执行mvn dependency:tree
后的依赖(仅展示部分):
[INFO] --- maven-dependency-plugin:3.0.2:tree (default-cli) @ springboot-weixin-alipay ---
[INFO] com.fengdu:springboot-weixin-alipay:war:0.0.1-SNAPSHOT

[INFO] | \- org.springframework.boot:spring-boot-autoconfigure:jar:2.0.3.RELEASE:compile
执行mvn dependency:tree -Dincludes=com.alibaba:
后的依赖树:
[INFO] --- maven-dependency-plugin:3.0.2:tree (default-cli) @ springboot-weixin-alipay ---
[INFO] com.fengdu:springboot-weixin-alipay:war:0.0.1-SNAPSHOT
[INFO] \- com.alibaba:druid-spring-boot-starter:jar:1.1.9:compile
[INFO] \- com.alibaba:druid:jar:1.1.9:compile
执行mvn dependency:tree -Dverbose
后的依赖树,可以看到依赖是否存在版本冲突。由于示例代码没有冲突,所以截取了其他项目扫描的结果:
[INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ esshop ---
[INFO] esshop:esshop:war:0.0.1-SNAPSHOT
