在脱机/断开连接时解决Apache Ivy依赖关系？

如何让 Ivy 在脱机/断开连接时从本地缓存解析依赖关系（包括 与 ） 的依赖关系？changing="true"

我正在开发一个基于Java的开源项目，该项目使用Apache Ivy来解决和下载第三方依赖项。该项目有一个名为“蚂蚁”的目标，该目标下载常春藤（如果需要），然后使用常春藤检索所需的罐子。build.xmlresolve

在线时一切正常。但是，如果没有 Internet 访问，即使所需的 jar 位于本地 Ivy 缓存中，也会失败 （）。Ivy 似乎正在尝试连接到 Maven 存储库以刷新依赖项。ant resolve~/.ivy2/cachechanging="true"

我得到的错误类似于以下内容：

[ivy:retrieve] You probably access the destination server through a proxy server that is not well configured.
