Maven:依赖关系的动态规范 [英] Maven: dynamic specification of dependencies

问题描述

我已经开始学习Maven并有以下问题:

I have started to learn Maven and have the following question:

我想动态指定用于构建Maven项目的依赖关系，而不是使用POM中指定的依赖关系-有办法吗?

I would like to dynamically specify a dependency for building maven project instead of using the dependency specified in POMs - is there a way to do that?

因此，尽管我在POM中指定了以下依赖项

So although I have the following dependencies specified in POM

...
<dependencies>
<dependency>
<groupId>group</groupId>
<artifactId>ProjectComponent</artifactId>
<version>1.0</version>
 </dependency>
...

我想在build命令中指定要使用其他版本. 有没有办法指定这个?

I would like to specify in the build command that I want to use a different version. Is there a way to specify this?

这个想法是，我想在Jenkins中建立一个集成构建，并依赖于特定分支机构系统的最新可用快照.该快照尚未发布到Maven存储库中，因此我想在Jenkins中获取它，并指定mvn构建的依赖项.

The idea is that I want to have an integration build made in Jenkins with a dependency on the latest available snapshot of the system for a particular branch. That snapshot is not released to the maven repository yet, so I would like to fetch it in Jenkins and specify a dependency for mvn build.

谢谢！

可能的解决方案:我最终得到的是使用$ {my.lib.version}构造，并在调用mvn时使用-Dmy.lib.version = 1.0-SNAPSHOT进行指定.因此，我可以通过从svn获取依赖项的任意快照版本并将其快照版本提供给集成构建pom来将其用于Jenkins集成构建.

POSSIBLE SOLUTION: What I ended up with is to use ${my.lib.version} construction and specify it with -Dmy.lib.version=1.0-SNAPSHOT" when calling to mvn. Thus I can use it for Jenkins integration builds by fetching arbitrary snapshot versions of dependencies from svn and feeding their snapshot versions to the integration build pom.
