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 [DEBUG] Imported: org.apache.maven.settings < plexus.core [DEBUG] Reading global settings from /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? Here is a screenshot showing the ‘?’ folder under $HOME: [image: Screenshot from 2019-12-04 18-40-35] <https://user-images.githubusercontent.com/39118/70199367-54c8c180-16c6-11ea-9cc7-d3c64a4cf619.png> Thanks, - Leira
