I just tested the linux installer in a docker container openjdk:10

That worked. In openjdk:9 I got: Caused by: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

@dominicm sorry for non-response above - I saw it but got distracted before answering and then the notifier was gone so forgot about it. :) I don’t test the linux installer very well (just in a vm) and would appreciate any help in making it better.

@borkdude if you’re trying to compare times, make sure that you’re comparing cached classpath in both cases by running more than once

they mentioned that jvm startup times should be expected to be better in java 10 than java 9

Possibly the SSL error is this? https://github.com/docker-library/openjdk/issues/145

I’m comparing 8 and 9 here with just vanilla clojure after it downloaded the bootstrap dependencies

it seems to be a little bit better

this is openjdk, no idea if there is any difference with the Oracle JDK

not a JVM expert

it’s very easy to spin up a Docker: docker run -it openjdk:10 /bin/bash and then do the clj linux installer

how to do test with tools.deps?

What are you trying to test?

I'm trying to use tools.deps instead of lein. I just want to run test like lein test.

Check out the test-runner project

this is exactly what I'm looking for, thanks!

Other useful tools

great

when I use git/url, met an error

org.eclipse.jgit.api.errors.TransportException: [email protected]:cognitect-labs/test-runner: UnknownHostKey: . RSA key fingerprint is

I'm confused what should I do?

@ghadi had a list of git connection issues in the back chat

In this case looks like maybe you’re using the ssh url when the https would be better

https would work because that repo is public

otherwise try ssh-keyscan -H >> ~/.ssh/known_hosts (I'm a bit surprised that http://github.com isn't in known_hosts -- perhaps you're containerized?)

I will update the test-runner read me to use https too

No reason for an ssh url there

I wonder where tools.deps put the git dependencies?

maybe I can find it with clj -Spath

okay, found it.

thanks a lot.

I opened an issue for that @alexmiller

where?

nvm, I see it

@doglooksgood take a look at the deps.edn file in each of core.cache, core.memoize, and java.jdbc for examples of multiversion testing with clj and test-runner -- I recently converted all of those from Leiningen.
