I work primarily on the JVM & the projects (personal/corporate) I work w/ can be summarised as below:
docker-compose.yml
.However one approach that I've always been fond of (& apply/advocate wherever I can) is to replace (3) w/ a
Makefile
containing a bunch of standard targets shared across all repos, egtest
,integration-test
. Then Makefiles are thinly customised to fit the repo's particular repo.This has proven to be very helpful wrt congnitive load (and also CI/CD pipelines): ALL projects, regardless of the toolchain, use the same set of commands, namely
make test
make integration-test
make compose-up
make run
In short (quoting myself here):
How do you manage JVM versions? We have many older projects that use 8, and some newer ones using 17, for example.
I've been using sdkman for about a decade now and am totally pleased w/ it. It does a very good job of managing JDK versions for you and much more, eg SBT, Gradle, Scala, Groovy, Leiningen, SpringBoot, ...
Now, technically you could use sdkman in your CI/CD pipeline too but I'd find it a strong smell. I've always used dedicated images pre-configured for a particular JDK version in the pipeline.
