support Clojure deps.edn as source for project libraries

[behrica]

Combined Clojure + Java development becomes very convenient as VScode supports both languages in a the same project.

In this context it would be super useful if a Java project could be based on the Clojure deps.edn file, which contains similar information as a pom.xml, specifically the project libraries.

(in fact I use a conversion tool from deps.edn -> pom.xml in order to have Clojure and Java classpath in sync)
