maven提供了一个命令 mvn dependency:tree可以直接打印出依赖树，例：

[INFO] com.qyf404:test-spring-boot:jar:1.0.0 [INFO] ± org.springframework.boot:spring-boot-starter:jar:1.5.4.RELEASE:compile [INFO] | ± org.springframework.boot:spring-boot:jar:1.5.4.RELEASE:compile [INFO] | | - org.springframework:spring-context:jar:4.3.9.RELEASE:compile [INFO] | ± org.springframework.boot:spring-boot-autoconfigure:jar:1.5.4.RELEASE:compile [INFO] | ± org.springframework.boot:spring-boot-starter-logging:jar:1.5.4.RELEASE:compile [INFO] | | ± ch.qos.logback:logback-classic:jar:1.1.11:compile [INFO] | | | - ch.qos.logback:logback-core:jar:1.1.11:compile [INFO] | | ± org.slf4j:jcl-over-slf4j:jar:1.7.25:compile [INFO] | | ± org.slf4j:jul-to-slf4j:jar:1.7.25:compile [INFO] | | - org.slf4j:log4j-over-slf4j:jar:1.7.25:compile [INFO] | ± org.springframework:spring-core:jar:4.3.9.RELEASE:compile [INFO] | - org.yaml:snakeyaml:jar:1.17:runtime

mvn dependency:tree -Dverbose，通过添加Dverbose来查看依赖树所有的依赖关系。

mvn dependency:tree -Dverbose，后面添加-Dincludes或-Dexcludes来展示你想查看或者过滤的jar包。

过滤串使用：groupId:artifactId:version的方式进行过滤，可以不用书写全

例：mvn dependency:tree -Dverbose -Dincludes=asm:asm

就会出来asm依赖包的分析信息： [INFO] — maven-dependency-plugin:2.1:tree (default-cli) @ ridge-test — [INFO] com.ridge:ridge-test:jar:1.0.2-SNAPSHOT [INFO] ± asm:asm:jar:3.2:compile [INFO] - org.unitils:unitils-dbmaintainer:jar:3.3:compile [INFO] - org.hibernate:hibernate:jar:3.2.5.ga:compile [INFO] ± cglib:cglib:jar:2.1_3:compile [INFO] | - (asm:asm:jar:1.5.3:compile - omitted for conflict with 3.2) [INFO] - (asm:asm:jar:1.5.3:compile - omitted for conflict with 3.2) [INFO] ------------------------------------------------------------------------

对asm有依赖有一个直接的依赖(asm:asm:jar:3.2)还有一个传递进入的依赖(asm:asm:jar:1.5.3)

承上，假设我们不希望asm:asm:jar:1.5.3出现，根据分析，我们知道它是经由org.unitils:unitils-dbmaintainer:jar:3.3引入的，那么在pom.xml中找到这个依赖，做其它的调整：

再分析一下，你可以看到传递依赖没有了： [INFO] [INFO] — maven-dependency-plugin:2.1:tree (default-cli) @ ridge-test — [INFO] com.ridge:ridge-test:jar:1.0.2-SNAPSHOT [INFO] - asm:asm:jar:3.2:compile [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS

mvn dependency:tree>tree.txt，也可以将依赖通过该命令导入到指定文件查看
