在Maven项目中，如何在< parent>中提到的以源/二进制形式下载库.在POM文件中标记? [英] In maven project How to download the library in source/binary, mentioned in the <parent> tag in POM file?

问题描述

这是pom文件.

<project>
 <parent>
   <groupId>org.jboss.weld</groupId>
   <artifactId>weld-api-bom</artifactId>
   <version>1.0</version>
   <relativePath>../bom/pom.xml</relativePath>
 </parent>

  <modelVersion>4.0.0</modelVersion>
  <artifactId>my-module</artifactId>

  <dependencies>
  <dependency>
     <groupId>javax.el</groupId>
     <artifactId>el-api</artifactId>
     <optional>true</optional>
  </dependency>
  </dependencies>

</project>

我知道，要下载依赖项(在其"el-api"之上)，我们应该使用

I know, to download the dependencies(above its "el-api") we should use

mvn dependency

但是用于下载父项依赖项(即weld-api-bom)的命令是什么?

But what is the command used to download the parent dependency(i.e weld-api-bom)?

推荐答案

鉴于您的父pom有 ../bom/pom.xml 它既可以下载(如果在配置的存储库中可用)，也可以从磁盘读取(如果有的话). 无论如何，大多数maven命令都会触发此工件的下载，这是构建的第一步.

Given your parent pom has ../bom/pom.xml It could either be downloaded (if avaiable in configured repository) or be read from disk if it there. In any case most of the maven commands will trigger the download of this artifact as one of the very first steps of the build.

请注意，"mvn依赖项"不是有效的命令.

Please also note that "mvn dependency" is not a valid command.
