我是使用maven和jenkins的新手.我试图继承从父pom到子pom的依赖关系，它显示以下错误:

I am new in using maven and jenkins. I am trying to inherit the dependencies from parent pom to child pom it shows the following errors:

这是我的父母POM:

..... <modelVersion>4.0.0</modelVersion> <groupId>group1</groupId> <artifactId>group1-artifact</artifactId> <version>1.0.1</version> <packaging>pom</packaging> <modules> <module>child1</module> </modules> .......

这是我的孩子POM:

..... <modelVersion>4.0.0</modelVersion> <parent> <groupId>group1</groupId> <artifactId>group1-artifact</artifactId> <version>1.0.1</version> <relativePath>(full url.....)/jenkins-parent-pom//pom.xml</relativePath> </parent> <groupId>group1</groupId> <artifactId>child1</artifactId> <version>0.0.1</version> <packaging>war</packaging> ......

这是我尝试从父POM继承子POM中的依赖项的方法:

Here is how I tried to inherit dependency in child POM from parent POM:

<dependencyManagement> <dependencies> <dependency> <groupId>group1</groupId> <artifactId>group1-artifact</artifactId> <version>1.0.1</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>

如果我将那些相同的依赖项放在子POM中，它会完美地工作.我使用jenkins在链接中进行clean install的安装和deploy部署.我正在使用maven-3.3.9.在詹金斯，我从git中阅读了两个不同的Maven项目中的父项和子项.我想从父POM继承所有依赖项和插件.是否有可能?

If I put those same dependencies in the child POM, it works perfectly. I do clean install for installing and deploy for deploying in nexus by using jenkins. I am using maven-3.3.9. In jenkins, I have read the parent and child poms in two different maven projects from git. I want to inherit all the dependencies and plugins from parent POM. Is it possible?

推荐答案

您应该在<dependencies>部分下声明要继承的依赖项，以实现此目的. <dependencyManagement>用于定义，以后需要时，必须在特定孩子的<dependencies>中引用该定义，以使其生效.

You should declare dependencies you want to inherit under a <dependencies> section to achieve this. <dependencyManagement> is used for definitions that must be referenced later, whenever needed, within the <dependencies> of a particular child to become effective.

更新:在声明每个子pom都将继承的依赖项时要小心.很快，您就可以拥有真正不需要的依赖项，因为它们是在父级中声明的.如其他评论者所述，尽管<dependencyManagement>并不是您最初想要的，但它可能是一个更好的选择.

UPDATE: Be careful when declaring dependencies that every child pom will inherit. Very quickly you can end up having dependencies you don't really need just because they are declared in the parent. As mentioned by other commenters, <dependencyManagement> may be a better choice, although it isn't what you wanted originally.
