FAILURE: Build failed with an exception.
* What went wrong:
Could not determine the dependencies of task ':test'.
> Could not resolve all dependencies for configuration ':testRuntimeClasspath'.
> Failed to calculate the value of task ':compileTestJava' property 'javaCompiler'.
> No matching toolchains found for requested specification: {languageVersion=17, vendor=any, implementation=vendor-specific}.
> No locally installed toolchains match (see https://docs.gradle.org/8.1.1/userguide/toolchains.html#sec:auto_detection) and toolchain download repositories have not been configured (see https://docs.gradle.org/8.1.1/userguide/toolchains.html#sub:download_repositories).
Since Gradle 8, the auto-provisioning does not work out of the box anymore.
You have to declare where to download toolchains from, for example by applying the foojay plugin as documented at the link given in the error message.
Point 4 is perfectly valid.
It will auto-download.
Point 4 is saying “on the configured toolchain download repositories”.
In Gradle 7 there were some hard-coded.
In Gradle 8 you need to configure some, for example using the plugin as documented and also mentioned in my last comment.
Just if you don’t configure any, it does not know where to download from.
It’s not very clear in the documentation what exactly one needs to setup to get auto downloads working *.
There’s an example of ‘made up’ in the docs.
So unless you already know how to set this up, it’s a great wall of text to those new to the whole great new ways of doing things.
I’ve been using gradle for years and used to spending time setting up stupidly complex config, but even I’m lost on this. Wasted hours on it already (upgrading to gradle 8 and all the new config). A line along the lines of:
TL;DR; “To setup the auto download for adoptium/whatever, use this config”.
Maybe this is buried in some sub page somewhere, so technically it’s there, but it’s hardly obvious to a newcomer. It’s helpful for there to be an on ramp for those not spending large chunks of their life in gradle config world
* Unless I really missed something obvious and am being a total blind
Not sure what your mean? It is directly documented what to use, and there is nothing “made up”. Do you maybe interpret “foojay” as “made up” just because it has “foo” in the name? It is not, as described above.
Did you also read the text around the example?
It clearly documents that one example earlier you have exactly the “just work” configuration you are after.
The example you quoted is for the more sophisticated case where you need a custom resolver for example because you have custom Java distributions or whatever.
