Moving Maven cache to another drive

[NightOwl888]

I want to move the Maven cache to another drive, since there are some large binaries in there and I am running low on disk space. However, according to https://howtodoinjava.com/maven/change-local-repository-location/, there doesn't seem to be a unified way to do it like there is for NuGet. Maven and Eclipse have to be configured individually.

For Maven, it says we need to change the {M2_HOME}\conf\settings.xml file (adding a <localRepository> element). But, with MavenReference do we even have a file? If so, where is it?

If not, consider this a feature request. Ideally this would not have to be set individually per project, but system-wide somewhere so each newly created project uses the same cache location.

You can make that file I believe.

[wasabii]

Well, the user version of it. I don't know about the global one.

[NightOwl888]

Well, I have another instance of Maven installed.

But we aren't using the environment variable. It is hard coded to user home: https://github.com/ikvmnet/ikvm-maven/blob/main/src/IKVM.Maven.Sdk.Tasks/MavenEnvironment.cs#L99

[NightOwl888]

Unless there is some way to change the property of user.home...

[wasabii]

All ya gotta do is put the file where it should be in your home.

Yeah, looks like that worked. Thanks.

Is there a way to move the IKVM cache?

[wasabii]

IkvmCacheDir property I think? Maybe IkvmCachePath. One of the two.

[wasabii]

Yeah, two of em:

IkvmCacheDir for jar->dll IkvmExportCacheDir for dll->jar

[NightOwl888]

Hmm...in MSBuild? Is there something at the user or system level?

[wasabii]

In Msbuild, yes.

Other than env variables, no. The only usage of the cache is MSBuild.
