In my work project, we use figwheel. Every time I start it, I get some spam in the REPL that seems unnecessary. (I’m using Cursive)

WARNING: Unable to create a system terminal, creating a dumb terminal (enable debug logging for more information)
Unable to detect a system Terminal, you must not launch the Rebel readline
from an intermediate process.
If you are using `lein` you may need to use `lein trampoline`.
I can remove the first three lines by adding
(System/setProperty "org.jline.terminal.dumb" "true")
to cursive_repl.clj. This has something to do with the jline3 library, which I guess IntelliJ uses for handling console output.
Then I’m left with:
Unable to detect a system Terminal, you must not launch the Rebel readline
from an intermediate process.
If you are using `lein` you may need to use `lein trampoline`.
This is something that figwheel produces because I’m using a “dumb” terminal, as far as I can read from the source code.
If I try to disallow using a “dumb” terminal by setting (System/setProperty "org.jline.terminal.dumb" "false"), the REPL crashes:
Syntax error (IllegalStateException) compiling at (dev/cursive_repl.clj:12:1).

So, I’m wondering if there is some way to get rid of the message, or if I’m stuck with it?I would prefer not to mess with our project.clj, since other people depend on it. There’s a rebel-readline dependency in :profiles {:dev {:dependencies vector, and I guess the people who are running from the terminal depend on that. We’ve got quite a few people developing on our frontend.
I’m wondering if perhaps there’s some way to override exactly that part of the profile when calling start-figwheel!, or something like that.
@reefersleep are you using lein-figwheel?
