so often we get people in the chat asking about what they could do to learn java! well, the java team's got ya sorted! check out their new channel, ⁨YouTube.com/@Learn-Java⁩ !

seriously, have you watched this fantastic talk by Java architect Ron Pressler on the principles of memory management in Java? www.youtube.com/watch?v=xr73mR7ii9M

yah you can set versions of JVM dependencies with SDKMAN when switching into directories. You can't set environment variables or run important setup code. You can't manage other kinds of packages like, say, ffmpeg with Mise, you can do all of this

Non merci je me debrouille assz bien en francais cest pas ma langue maternelle mais je laime beaucoup

And I’d love to see ur French language video on it Too :-)

mise is AWESOME! i should do a video..

I appreciate that. Oracle tells everyone the release day for weeks or months ahead of time Is there some way that you could teach me to handle the process? I’m happy to donate both cash and time to your amazing effort, in order to close this last little gap

010

See? Now we’re back at square 1: sdkman (in theory) does ALL of this and that’s why it’s so useful :) Just slow to pickup releases

101

Neat. How do I switch between them?

100

I think I need to investigate. does mise have openjdk java 27 ? and does it support the equivalent of .sdkmanrc?

100

I love sdkman but it's failing on this very important (to me) metric: can we capture the energy+marketing+enthusiasm on release day? Oracle pays scores of people to put together the release, do social media, do launch-day streams, and then its squandered b/c for folks using SDKMAN it doesnt exist

230

im happy to pay so that a) the integration is fixed b) someone (u, me, scores of folks from oracle, etc.) could login on to whatever systems are there on release day, upload a zip, and hit 'go live' or whatever the integration requires.

100

thanks. but time is only an issue when the automation's broken. i'm happy to pay to fix it. I think @hansolo.eu said something about the integration between the two - DISCO and SDKMAN - being broken and he'd revisit it when he got home from his travels.

100

ill donate $$ if that would help, but is the problem in SDKMAN or in Disco? there's some bug in the integration, I thought?

100

the main issue is that there's this infernal lag - days or weeks - between when a new package (like Java 27) appears and when I can install it w/ SDKMAN. 6/N

200

but since there can only be one JDK per operating system, how would I first uninstall or 'disable' the other ones? these are problems I dont have with sdkman. 5/N

200

theres a handy, orthogonal tool call direnv which has this cd-into-a-directory-and-activate-an-environment mechanism. its not tied to any tool or environment variables tho in theory I suppose I could use direnv and ports / home-brew and just have it install java versions using a package manager 4/N

100

if I type java --version in ~/code/ancient-crap, it'll show java 8. (and trigger my gag reflex) 4/N

200

this is because of the presence of .sdkmanrc which gets evaluated by the shell and ensures that, in that working directory, java is the one I want it to be. SDKMan can do that fro all sorts of other jvm dependencies too. kotlin, Gradle, maven, etc. 3/N

100

and I am working on all 3 in different times. with pipenv (python), nodenv (node), sdkman (jvm), javaenv (jvm), rbenv (ruby), uv (python), etc., its possible to simply `cd` into this directories and when I type java --version, the current version of java is the version I want. 2/N

100

so, imagine I have a java 8 project in ~/code/ancient-crap, a Liberica java 21 project in ~/code/old-and-busted and I have an openjdk java 27 project in ~/code/new-shiny, 1/N
