How to get all versions (including invisible ones) in SDKMAN

Question

SDKMan has many more versions then that are shown when doing a 'sdk list'. I would like to see those as well, so I can install older versions. SDKMan's API seems to be selective in what it shows, but I cannot find any documentation on it. Based on inspecting the CLI sources I found these URLs:

To list all candidates, like maven, java, etc:

https://api.sdkman.io/2/candidates/all

To get versions for one candidates for one platform (e.g. maven on windows):

https://api.sdkman.io/2/candidates/maven/win/versions/all

The problem is some candidates, most notably java, do not return possible versions in that url. The response is empty.

What am I doing wrong or missing? How can I get all versions for all candidates?

Answer 1

As of https://github.com/sdkman/sdkman-candidates/blob/master/conf/routes java seems to be a special case.

At https://api.sdkman.io/2/candidates/java/linuxx64/versions/list?installed= I get a list of versions.

You can look up the platforms in https://github.com/sdkman/sdkman-candidates/blob/master/app/utils/Platform.scala

Answer 2

From what I have learned, this cannot be done; the API simply does not return the information. But I'd very gladly like to be proven wrong.
