Mise non-vendored openjdk and raw versions are not up-to-date

[rocketraman]

Describe the bug Doing mise ls-remote java lists both vendor distributions as well as non-vendor distributions like "openjdk-*" as well as just the raw versions like "17" and "21".

I don't know which distributions are actually provided by values like "openjdk-17", "openjdk-21", "17", and "21" (and possibly others) [1], but they are out of date.

[1] As an aside it would be helpful to show which entries were actually links to other entries in the output of ls-remote, like ls -l does.

To Reproduce

Taking the most recent LTR release versions:

# mise ls-remote java | grep "^17"
mise pruning old cache files, this behavior can be modified with the MISE_CACHE_PRUNE_AGE setting
17.0.0
17.0.1
17.0.2

# mise ls-remote java | grep "^21"
21.0.0
21.0.1
21.0.2

but seeing what is available from the various vendors we can see that 17.0.12 and 21.0.4 are available:

# mise ls-remote java | grep adoptopenjdk-17
adoptopenjdk-17.0.0+35
adoptopenjdk-17.0.1+12
adoptopenjdk-17.0.2+8
adoptopenjdk-17.0.3+7
adoptopenjdk-17.0.4+101
adoptopenjdk-17.0.4+8
adoptopenjdk-17.0.5+8
adoptopenjdk-17.0.6+10
adoptopenjdk-17.0.7+7
adoptopenjdk-17.0.8+101
adoptopenjdk-17.0.8+7
adoptopenjdk-17.0.9+9
adoptopenjdk-17.0.10+7
adoptopenjdk-17.0.11+9
adoptopenjdk-17.0.12+7

# mise ls-remote java | grep adoptopenjdk-21
adoptopenjdk-21.0.0+35.0.LTS
adoptopenjdk-21.0.1+12.0.LTS
adoptopenjdk-21.0.2+13.0.LTS
adoptopenjdk-21.0.3+9.0.LTS
adoptopenjdk-21.0.4+7.0.LTS

Expected behavior I would expect the non vendor specific entries to have a more recent version provided.

The shorthand (non-prefixed) version refers to openjdk which only receives updates for 6 months after GA. Java metadata is provided by https://github.com/jdx/rtx-java-metadata.

Thank you for the quick response and clarification of the behavior. My follow up question would be: does it make sense for the raw numeric shortcuts to refer to the non-updated openjdk?

Or perhaps there should be a config mechanism to set the preferred vendor for the non-qualified values?

[rocketraman]

Also a related request would be: allow specifying the latest version of a specific vendor. For example:

java@corretto-17

would refer to the latest version of corretto JDK, just like 17 refers to the latest version of openjdk-17.

I can open separate issues for these things if that makes sense.

Ah, I see it already does this. It just doesn't list these options in ls-remote. I'd love to see the output of ls-remote look something like this:

temurin-21.0.0+35.0.LTS
temurin-21.0.1+12.0.LTS
temurin-21.0.2+13.0.LTS
temurin-21.0.3+9.0.LTS
temurin-21.0.4+7.0.LTS
temurin-21 -> temurin-21.0.4+7.0.LTS

I personally like the idea of having another vendor (than openjdk) for a shorthand. Not sure how feasible this will be though, will check it out if i find some time.

I don't think mise should list non-existent artifacts. This is more of a versioning behaviour of mise which is implicit.

[jdx]

that output would break scripts

I'm not really in favor of using a different vendor for the shorthand just because my understanding is that openjdk is generally considered the "standard" and the most popular. I think anything else as the default would be surprising even if we think it's something more users would prefer.

[jdx]

that said, I'd be open to making the default jdk a setting

[rocketraman]

that output would break scripts

How about gated behind a flag like --show-links or something like that? It would increase discoverability greatly. For example, I had no idea I could use temurin-latest and temurin-17 until I raised this issue and dug into things on my own.

[jdx]

they aren't links, it's just prefix matching

[rocketraman]

they aren't links, it's just prefix matching

Ah, ok. temurin-latest isn't a prefix -- is "latest" a special case?

[roele]

I agree that openjdk should stay the default. Having a setting (e.g. java_shorthand_vendor) might be something we can add relatively easily. But this is rather something that would need to be used cautiously as a project with a tool java = "23" might install a different Java distribution for someone having this changed.

[rocketraman]

But this is rather something that would need to be used cautiously as a project with a tool java = "23" might install a different Java distribution for someone having this changed.

That is true. Maybe the setting should only apply to global installs, and not per-project installs. Per-project installs should use the same JDK consistently on different machines and users.

[roele]

For some this behaviour could even be desired as #1674 shows. But such a setting (on project level) would also mess with the major/minor/patch symlinks that are created. So in the end i'm leaning towards keeping things as they are.

[jdx]

I actually don't see any use-case for globally using such a setting. Though I also see no reason to restrict it, @roele is right we wouldn't have support for doing one and not the other anyways. I can think of one for projects though.

I could see a maintainer just wanting to define a Java version without mandating a particular flavor.

Of course this is what mise.local.toml is for but maybe if a company has a lot of Java projects but loose restrictions on the flavor it might be handy.
