How to override the location of Ivy's Cache?

Question

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.

Answer 1

Something like this in 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

Answer 2

I'm use Jenkins as CI build system, and create $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.

Answer 3

Although the answer above from skaffman is correct, I found it to be a lot more work than I had expected!

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.

so, I found out how to add the new cache directory to the in-line command-line within my NAnt script...

< 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.)

This means that I don't need the ivysettings.xml file, and I can revert everything back to using the default resolvers, etc.
