How to override the location of Ivy's Cache?
提问by Brett Rigby
I am using Ivy as part of my continuous integration build system, but I need to override the default location that Ivy's local cache area is.
我使用 Ivy 作为持续集成构建系统的一部分，但我需要覆盖 Ivy 本地缓存区域的默认位置。

Although the answer above from skaffman is correct, I found it to be a lot more work than I had expected!
虽然上面来自 skaffman 的答案是正确的，但我发现它比我预期的要多得多！
When I added the ivysettings.xml file to the project, I then needed to redefine almost everything, as the default values had been working fine until then.
当我将 ivysettings.xml 文件添加到项目中时，我需要重新定义几乎所有内容，因为在此之前默认值一直工作正常。
so, I found out how to add the new cache directory to the in-line command-line within my NAnt script...
所以，我发现了如何将新的缓存目录添加到我的 NAnt 脚本中的内嵌命令行中...
< exec program="java" commandline="... ... -jar ${ivy.jar} -cache ${project.cache} ... ... />
(Where ${ivy.jar}is the location of my .jar file and ${project.cache}is the new location set earlier in the script where I want the cache area to use.)
（${ivy.jar}我的 .jar 文件${project.cache}的位置在哪里，是我希望缓存区域使用的脚本中前面设置的新位置。）
This means that I don't need the ivysettings.xml file, and I can revert everything back to using the default resolvers, etc.
这意味着我不需要 ivysettings.xml 文件，我可以将所有内容恢复为使用默认解析器等。

Something like this in ivysettings.xml:
像这样的东西ivysettings.xml：
<ivysettings>
<caches defaultCacheDir="/path/to/my/cache/dir"/>
</ivysettings>
See documentation at http://ant.apache.org/ivy/history/latest-milestone/settings/caches.html
请参阅http://ant.apache.org/ivy/history/latest-milestone/settings/caches.html 上的文档

I'm use Jenkins as CI build system, and create $HOME/.ivy2/ivysettings.xml：
我使用 Jenkins 作为 CI 构建系统，并创建 $HOME/.ivy2/ivysettings.xml：
<ivysettings>
<properties environment="env" />
<caches defaultCacheDir="${env.WORKSPACE}/.ivy2/cache" />
</ivysettings>
This create the ivy cache dir at each jenkins job's workspace.
这会在每个 jenkins 作业的工作区创建常春藤缓存目录。
