Question

当您运行mvn dependency:tree到某个Spring Boot项目时，您会看到以下内容：

[INFO] com.example:demo:jar:1.0.0-SNAPSHOT
[INFO] +- org.springframework.boot:spring-boot-starter:jar:2.0.1.RELEASE:compile
[INFO] |  +- org.springframework.boot:spring-boot:jar:2.0.2.RELEASE:compile
[INFO] |  |  \- org.springframework:spring-context:jar:5.0.6.RELEASE:compile
[INFO] |  |     +- org.springframework:spring-aop:jar:5.0.6.RELEASE:compile

[INFO] |  |  \- org.springframework:spring-jcl:jar:5.0.6.RELEASE:compile
[INFO] |  \- org.yaml:snakeyaml:jar:1.19:runtime

当您不重写时，所有工件都从父pom获得了默认版本。是否有一些Maven命令来检查项目父项的信息（版本）？

所以当pom.xml中存在

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.2.RELEASE</version>
</parent>

我想看到类似的东西

[INFO] +- org.springframework.boot:spring-boot-starter-parent:jar:2.0.1.RELEASE:compile

Answer 1

这没有显示您想要的确切输出，但是非常相似。

mvn -Dexec.executable='echo' -Dexec.args='${project.parent.groupId}: ${project.parent.artifactId}: ${project.parent.version}' --non-recursive exec:exec -q

在Ubuntu上测试，它在我的机器上显示如下内容：
org.springframework.boot: spring-boot-starter-parent: 1.5.9.RELEASE

-q ：安静的输出，仅显示错误

mvn依赖项的替代项：查看父版本的树
