I use Nix under Debian. I installed clojure through nix-shell -p clojure.
clj successfully started the repl after downloaded some poms from maven.
Then I found there is a folder named ‘?’ created under my $HOME. The maven
cache .m2 is under this ‘?’ folder. I tried leiningen, it is the same.
I suppose it should be a Java related issue rather than Clojure. So I tried
to install Maven and try with mvn. A simple mvn archetype:generate created
a '?'/.m2 folder under the current folder. mvn clean -X|grep setting shows:
$ mvn clean -X|grep setting

/nix/store/jyrx2vh4kg1dhbyil63bclpkfhbq6r2i-apache-maven-3.6.2/maven/conf/settings.xml
[DEBUG] Reading user settings from ?/.m2/settings.xml
Where is this ‘?’ folder from? Is it expected behavior? How do I get rid of
it?
Delete ~/.m2 and start the Java process with strace, upload that file.
We will see direct system calls.
