Maven：如何在Eclipse中包含jar，它们在存储库中不可用？ [英] Maven: How to include jars in Eclipse, which are not available in repository?

问题描述

我已将JAR复制到 src\main\webapp\WEB-INF \ lib 。

我使用eclipse。如果我将jar一个一个地添加到Project-> Java Build Path-> Add jars，然后我执行Project-> Maven-> Update Project Configuration，它们将被Maven删除。 Eclipse显示错误，其中包含xxx无法解析。

I have copied the JARs into src\main\webapp\WEB-INF\lib.
I use eclipse. If I add the jars one-by-one to Project-> Java Build Path-> Add jars, then I do Project-> Maven-> Update Project Configuration, they are removed by Maven. And Eclipse shows errors, which contain " xxx cannot be resolved".

Env:
Eclipse Java EE IDE for Web Developers.
Version: Indigo Service Release 1
Build id: 20110916-0149

m2e - Maven Integration for Eclipse 1.0.100.20110804-1717

注意：我不想创建自己的Maven存储库。它只会被使用一次。

我该怎么办？

Note: I don't want to create my own Maven repository. It will be just used once.
How should I proceed ?

推荐答案

并非所有的库都可以找到在公共Maven存储库中，例如您自己的库或专有库。无论如何，首先你可以搜索Maven资源库，也许其中一些存在。

Not all libraries can be found in a public Maven repository, for example your own libraries or proprietary libraries. Anyway first you can search the Maven Repository, maybe some of them are there.

如果它们确实不存在，并且您不想安装 Nexus 或< a href =http://www.jfrog.com/products.php =noreferrer> Artifactory ，您可以选择以下两种方法之一：

In case they are really not there, and you don't want to install Nexus or Artifactory, you can choose one of these two approaches:

• 将jar安装在本地存储库缓存中，无需创建特殊存储库。请参阅有关mkyong的说明。

另一种方法是使用系统依赖，你只需要在文件系统中放置一个到达Jar的路径。这是一种不太推荐的方法，但如果你真的想要它会起作用。这是官方文档。

another approach is using system dependencies, you just put a path to reach the Jar in the filesystem. It's a less recommended approach, but if you really want it will work. Here is the official documentation.
