使用maven复制同一个jar的两个版本 [英] Copy two versions of same jar using maven

问题描述

我正在为我们的项目编写pom.xml。我需要复制同一个jar的两个不同版本。但我搜索maven文档，发现Maven不支持这个。有没有其他方法可以做到这一点？

I am writing pom.xml for our project. I need to copy two different versions of same jar. But I searched maven docs and found that Maven has no support for this. Is there any other way to do that?

注意：两个jar有相同的groupid和artifact id.Only他们的版本是不同的。

Note: Both jars have same groupid and artifact id.Only their versions are different.

提前感谢！

推荐答案

正如你已经知道的，Maven的目的是确保你永远不会有两个具有相同坐标（组+工件id）但在类路径上有不同版本的JAR。

As you already know, Maven was designed to make sure that you will never have two JARs with the same coordinate (group + artifact id) but different versions on the classpath.

没有办法实现你想要的而不修改JAR的POM

因此，您需要一个解决方法。这里有几个解决方案：

So you need a workaround. Here are a couple of solutions:

1. 给JAR不同的分类器。典型的分类器是测试和来源，但它们可以是任何内容。

1. Give the JARs different classifiers. Typical classifiers are "tests" and "sources" but they can be anything.

将版本号移动到工件ID并给予两个JAR

Move the version number to the artifact id and give the two JARs a new version.

对于所有方法，您需要下载JAR（也可能是他们的POM）再次使用 mvn file：install （更改POM之后）或使用 mvn deploy：file 部署自己的Maven代理。

For all approaches, you will need to download the JARs (and probably their POMs as well) and install them again using mvn file:install (after changing the POMs) or deploy them with mvn deploy:file if you run your own Maven proxy.
