When using :local/root with a .jar will that resolve transitive dependencies of the jar by inspecting the pom.xml inside that jar? And is it standard that pom.xml is included in the jar?

Is that supposed to work? I’m surprised

Yeah, it’s documented: Local jar: {:local/root "/path/to/file.jar"}. TIL

Yeah, it's pretty neat. I just wasn't aware that pom.xml is always(?) part of the jar so thought that this couldn't work with transitive deps.

It is normally part of the jar.

what might be the reason that it takes a very long time to get a REPL up? I just upgraded my ArchLinux and before it took a few seconds, now, minutes. I believe the only change is the upgrade of the jdk 8.u192-1 -> 8.u202-1.

If I don't include the 'dev' profile, which has some machinery with tools.namespace (and a logback.xml) in it, it goes back to seconds.

well the main thing it’s doing is network I/O so that would be my default area of concern

do some stack traces with ctrl-\ while it’s working and see what it’s doing

8.u201 (and 202) include new buffer overrun checks in Linux, not sure if that would affect visible perf: “Additional safeguards to protect against buffer overruns in native code have been enabled on Linux. If a buffer overrun is encountered the system will write the message “stack smashing detected” and the program will exit. Issues of this type should be reported to your vendor.”

if I switch to java 11 it's back to 'seconds'

it looks like the compilation of namespaces that are required from user is slow. when these are uncommented, it's fast on 8.u202 too

hmm, still not clear to me what the difference is

could you post your user.clj maybe?
