感谢任何帮助。

$ b $在eclipse中，你必须创建一个新的 maven java项目。如果您不知道 maven ，您可以在这里获取信息：

apache maven startsite

如何安装maven

您可以在 pom中配置依赖项。 xml 文件。哪个是maven的配置文件。

您可以在这里找到一些依赖关系：

maxmind文档

依赖项的包含如下所示：

 <依赖关系> 
< groupId> com.maxmind.geoip2< / groupId> 
< artifactId> geoip2< / artifactId> 
< version> v2.3.0< / version>

I'm trying to use MaxMind's GeoIP2 database, I've added the jar to my Java build path and configured it with Javadoc and source but when I run the program I get a NoClassDefFound error, which according to this stack overflow answer is because I need to add the dependencies, but I have no clue how to add them in eclipse, I tried extracting the jar files and adding them to the build path but that didn't work, how do I do this in eclipse?

Thanks for any help.

解决方案

In eclipse you have to create a new maven java project. If you dont know maven you can get informations here:

apache maven startsite

how to install maven

Afer that you are able to configure your dependencies in your pom.xml file. Which is the configuration file for maven.

You can find some dependencies for your usage here:

maxmind documentation

The include of the dependency would look like this:

 <dependency>
    <groupId>com.maxmind.geoip2</groupId>
    <artifactId>geoip2</artifactId>
    <version>v2.3.0</version>
</dependency>

But first, you should look at maven installation and using. It will make your life easier by handling all the necessary dependencies you will need in this project and in all of your other projects in future.
