离线/断开连接时,如何让Ivy解决本地缓存中的依赖关系(包括changing="true"
的依赖关系?)
我正在开发一个基于Java的开源项目,该项目使用Apache Ivy来解析和下载第三方依赖项。该项目的build.xml
有一个名为resolve
的蚂蚁目标,下载常春藤(如果需要),然后使用常春藤来检索所需的罐子。
在线时一切都很棒。但是,如果没有Internet访问,即使所需的jar位于本地Ivy缓存(ant resolve
)中,~/.ivy2/cache
也会失败。似乎Ivy正在尝试连接到Maven存储库以刷新changing="true"
依赖项。
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.

按照警告的建议运行ant -verbose resolve
会在输出中打印以下行:

如何在离线时让Ivy从缓存中解析changing="true"
个依赖关系,但在线时继续查询每个版本的存储库?
答案 0 :(得分:12)
尝试从命令行运行构建设置 ivy.cache.ttl.default 属性:
ant -Divy.cache.ttl.default=eternal build
