we sort these using the rust semver crate which isn't handling this version correctly.

looking at the output of rtx ls-remote java I really don't know if we'll ever be able to properly sort everything in there unfortunately. A lot of java runtimes just behave really strangely.

[kien-truong]

What I find odds is sometimes it sorts correctly, for example

temurin-11.0.14+9
temurin-11.0.14+101

Also, I think temurin-17.0.8+101 is actually version 17.0.8.1+1, which somehow got converted into 17.0.8+101

I think what needs to happen is 2 things:

• plugin trait needs to be modified to include some sort of function to compare versions using semver as the default but allowing java.rs to override with custom logic.
• somehow we need to figure out how to actually sort all of the versions and put that logic into this override function. This might need to be different for each flavor of java.

As far as what the override function could be, I'm not really sure how best to use the PartialOrd trait here but maybe we could just start with this:

fn partial_cmp(a: &str, b: &str) -> Option<std::cmp::Ordering>

If someone wanted to write that function even just for temurin, it could just be a simple playground script that I can work to integrate in the codebase.

I think I managed to resolve this actually without needing to do what I mentioned before. Now rtx uses https://rtx-versions.jdx.dev/java for the versions which I pipe through sort -V and I think it sorts it correctly:

$ rtx ls-remote java | grep temurin-11
temurin-11.0.12+7
temurin-11.0.13+8
temurin-11.0.14+9
temurin-11.0.14+101
temurin-11.0.15+10
temurin-11.0.16+8
temurin-11.0.16+101
temurin-11.0.17+8
temurin-11.0.18+10
temurin-11.0.19+7
temurin-11.0.20+8
temurin-11.0.20+101
temurin-11.0.21+9
