jar的POM无效，传递依赖项将不可用

问题描述

我想在Eclipse中为我的Maven项目提供外部依赖.因此，我将jar文件及其POM.xml直接复制到了本地Maven存储库中.但是Eclipse以某种方式抱怨该jar的POM无效.

I want to provide external dependency to my maven project in eclipse. Therefore, I ave copied the jar file and its POM.xml directly in the local Maven Repository. But somehow Eclipse is complaining that the POM for the jar is invalid.

我的本​​地存储库中的jar文件的pom.xml如下所示:

My pom.xml for jar file in local Repository looks like below:

我已经检查了类似的帖子，并在eclipse.ini中进行了必要的更改(将JDK的JRE指定为vmargs n all).我对MAven Project的依赖如下所示:

I have already checked similar posts and have done necessary changes in eclipse.ini (specifying JDK's JRE as vmargs n all). My dependency in MAven Project looks like below:

<dependency>
            <groupId>com.b.t</groupId>
            <artifactId>v-p</artifactId>
            <version>1.1.0</version>
        </dependency>

请注意，带有相应POM.xml的同一个jar文件对于我的Intellij同事来说效果很好.

Please note that the same jar file with corresponding POM.xml is working well for my colleague in Intellij.

我仅使用Eclipse Luna来获取信息.我还在Eclipse中检查了已安装的JRE为jdk1.8.0_144.

I am using Eclipse Luna just for info. I also have checked in my Eclipse that the Installed JRE is jdk1.8.0_144.

在命令提示符下使用mvn clean install时，我也遇到相同的错误.

Also I am getting the same error when I use mvn clean install on command prompt.

有人可以建议我进一步检查什么吗?

Could someone please suggest what can I check more ?

推荐答案

您不能仅将文件复制到本地存储库中，而需要安装它们.这里有说明: https://maven.apache .org/guides/mini/guide-3rd-party-jars-local.html

You cannot just copy the files into your local repo, you need to install them. There are instructions here: https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html

在您的情况下是这样的:

In your case is would be something like:

mvn install:install-file -Dfile=<path-to-file> -DpomFile=<path-to-pomfile>
