Is there a solution for multiple gradle versions and sharing same cache?

Wait, the dependency cache is cachable I believe?

Yeah, that is fine

Dependencies are under

~/.gradle/caches/modules-2/

. It's the same directory for all Gradle versions

We share build agents between apps and usually in different grade versions and sometimes even a couple of them

Can you maybe elaborate a bit on what you actually mean with your question? It might be a bit too blurry for us to understand what you mean without your context knowledge.

We have 1TB of the hard drive for physical CI agent. That space goes off because of gradle cache recently.

And your question is what?

if different gradle versions could share build cache

They technically do share the build cache, it is

<GRADLE_USER_HOME>/caches/build-cache-1/

. The problem is, that the runtime classpath is an input, so for different Gradle versions the runtime classpath is different, so the cache fingerprints are different, and so you will not have cache hits across Gradle versions.

We don't have a remote build cache yet

The safest route is probably to get your gradle versions aligned 🤔

Not that it would change too much, even if different projects use the same Gradle version, usually other task inputs are different anyway. 🤷‍♂️

True...very much depends on the build... it might help if multiple projects had the same included builds But as you say...likely not

if multiple projects had the same included builds

Then those should anyway best have identical Gradle versions or you come rather quickly in devil's kitchen
