EDITED: See thread... new question : should the tools.build example in the documentation use --release and not -source/-target ? Can I safely ignore warnings regarding "`system modules path not set in conjunction with -source 11"` or "bootstrap class path not set in conjunction with -source 8" when using tools.build javac with either _:javac-opts_ ["-source" "11" "-target" "11"] or _:javac-opts_ ["-source" "8" "-target" "8"] ? Should I manually switch to the correct version of java as part of my build, and then use that? I'm using openjdk 17 but want to build a library made up of Java and Clojure code that targets 11 and above.

I realise that this is more of a Java question than a Clojure/tools.build question, but I used to compile my Java sources in a separate project using maven, and don't recall having this warning.

Typical, I post to slack and then work out the answer.

I appear to have fixed the issue with using --release instead of -source and -target. This apparently is better for cross-compilation. Should the tools.build docs use --release and not -source and -target as per https://stackoverflow.com/a/43103038 ?

yes, should probably make that switch

I think the small issue is that java 8's javac is still -source and -target

Alex Miller (Clojure team)13:06:35

but probably time to assume newer
