Question

我想运行Junit来比较xml的响应。为此，我想使用org.xmlunit，我在我的pom中添加了依赖项，如下所示

<dependency>
    <groupId>org.xmlunit</groupId>
    <artifactId>xmlunit-core</artifactId>
    <version>2.0.0</version>
    <scope>test</scope>
</dependency>

然而，当我运行maven install时，我遇到了以下错误。我在eclipse中使用嵌入式maven（Mars Release（4.5.0））。有人可以帮我解决这个错误。

Answer 1

该工件在MavenCentral中可用，因此如果您无法下载它，您很可能遇到某种网络问题，导致您的Maven无法连接到MavenCentral的网址。这可能是代理（通常在大公司内部）或防火墙。

Answer 2

检查您的连接，您无法连接maven中央存储库。

如果您使用Artifactory或Nexus，请检查您的外部存储库配置（Artifactory中的虚拟代理服务器）和代理连接。
如果您没有使用Artifactory或Nexus检查您与maven central的直接连接，可能您有代理限制。

无法在我的pom
