Recently, like today, I became interested in learning programming with clojure. Now, having installed the latest version of java jdk and downloaded the leiningen script, I followed the installation instructions for the latter, in particular those given at: http: /www.lispcast.com/clojure-ubuntu .
Now, after starting lein versionand loading the corresponding jar file, the program will exit with an error stating that the class was not found. The indicated error is read as follows:
An exception is

My java 9 jdk is set to /usr/lib/jvm/java-9-oracle/bin/java, and my variable is JAVA_HOMEset to /usr/lib/jvm/java-9-oracle, but I tried /usr/lib/jvm/java-9-oracle/bin, just in case. I am running xubuntu 16.04.3 if that matters. I tried to install java jdk by default in openjdk, which is related to xubuntu, but that also did not help.
