Problem description

Installing older versions of jdtls fails because there is a hardcoded timestamp in the url of the mason-schema-registry

I initially posted an issue on the mason-tool-installer repository but I think it makes more sense to post the issue here. https://github.com/WhoIsSethDaniel/mason-tool-installer.nvim/issues/35

As one can see here there would exist a latest.txt file containing the full filename with the timestamp. Maybe it would be possible to look up the filename by first fetching https://download.eclipse.org/jdtls/milestones/1.27.1/latest.txt. That way the url is only depending on the version number and not on the timestamps.

The issue was already mentioned in a discussion so I thought I'm not alone with this problem.

Expected behavior

Specifying older versions of jdtls in :MasonInstall successfully installs them.

Affected packages

jdtls

After 2 tiring days of trying to install, I temporarily fixed it with this method: Open ~/.local/share/nvim/mason/registries/github/mason-org/mason-registry/registry.json Find jdtls and change source.id, jdtls.tar.gz :MasonInstall jdtls

That's exactly what I did as well :-) Not the best user experience though^^

[s1n7ax]

There is latest.txt for every version that contains the file name of the tarball if that helps.

https://download.eclipse.org/jdtls/milestones/1.23.0/latest.txt

launcher is also hard coded so it's about time this is causing issues.

jdtls/plugins/org.eclipse.equinox.launcher.jar: plugins/org.eclipse.equinox.launcher_1.6.500.v20230717-2134.jar

Open ~/.local/share/nvim/mason/registries/github/mason-org/mason-registry/registy.json

There is a typo. Fixed path: ~/.local/share/nvim/mason/registries/github/mason-org/mason-registry/registry.json.

There is latest.txt for every version that contains the file name of the tarball

Yeah, I also wonder why it is not utilized.

[mikeyT42]

When trying to apply these changes, Mason is overwriting the changes to registry.json. Why is this; is anyone else having this issue?

[s1n7ax]

I think right now the only good solution is to have a custom registry with the packages you want. Even adding local path requires some yaml parser. Even when I tried last week, it did not work. I started doing jdtls package versioning by mason packages just like in NixOS.

Ex:- https://github.com/nvim-java/mason-registry/blob/main/packages/jdtls-1.33.0/package.yaml

If you are willing to add the necessary package version, I'm willing to accept the PR.

Repeating my suggestion from https://github.com/mason-org/mason-registry/issues/3017#issuecomment-2089994950 here:

Following the purl specs I wonder if we could add the required timestamp a qualifier to the package id:

id: pkg:generic/eclipse/[email protected]?timestamp=202404031240

This should make it easy to reference it in the source.file.download section.

Alternatively we could append it to the version separated with a dash:

id: pkg:generic/eclipse/[email protected]

Then split it with an expression to create the final download URL.
