Maven：无法解析依赖关系。找不到特定的 jar

Question

我在 github 上找到了一个项目，其中提供了 pom.xml 文件，该文件在 maven 中编译为 war 文件。但是，构建项目失败并提供警告，指出无法找到特定依赖项 (com.emc.cto.xProcRESTFramework) 的 POM。我查看了项目的文件夹，不存在这样的文件。我已经尝试在网上查找，但找不到依赖项。

我做错了什么？

感谢您的帮助！

以下是 maven 在尝试全新安装时产生的错误。

Answer 1

添加此依赖项，它将根据我的需要工作：

<dependency> <groupId>com.emc.cto</groupId> <artifactId>XProcRESTFrameworkMVC</artifactId> <version>0.0.4-SNAPSHOT</version> </dependency>

Answer 2

据我所知，它不在公共仓库中，但您可以从这里下载源代码：https://community.emc.com/docs/DOC-10494（需要注册）。

Answer 3

Maven 的存储库中不存在 xProcRESTFramework。

http://search.maven.org/#search%7Cga%7C1%7CxProcRESTFramework

如果您可以找到 xProcRESTFramework 文件，您可以创建一个本地 maven 存储库并将其添加到您的 maven 项目中。
