Build from source, clojure, lein test erroring out

[Chouffe]

Description

When building MXNet from source and running lein test using the locally built jar, it errors out with a lot of java.lang.Exception: = expects more than one argument.

Environment info (Required)

Here is how I build from source (mostly following the instructions from the docs). I could reproduce on Ubuntu 18.04 and 18.10:

1. git clone https://github.com/apache/incubator-mxnet.git
2. cd docs/install and then ./install_mxnet_ubuntu_python.sh
3. installing maven sudo apt-get install maven
4. Install Java 8:

sudo apt install oracle-java8-set-default

5. cd scala-package and then maven install
6. cd contrib/clojure-package and then lein test

You should see some errors like this:

...
