Hello all, I am following your instructions under [Lightweight Contracts](https://ardordocs.jelurida.com/Lightweight_Contracts) to get IntelliJ IDEA running on Ubuntu. However, starting the contractrunnersuite fails with 81 tests ignored and 1 failed. Looking through the output, I find this exception: > User home folder /home/mal/Ardor > Loading nxt-default.properties from classpath > Loading nxt-installer.properties from classpath > Loading nxt.properties from test/java/unit-tests-nxt.properties > java.lang.IllegalArgumentException: Error loading nxt.properties from test/java/unit-tests-nxt.properties > at nxt.Nxt.loadProperties(Nxt.java:174) > at nxt.Nxt.(Nxt.java:157) > .... I wonder where I should put a nxt.properties file, and what the content should be. Thanks for your help ---

It's a bug. To workaround it create a file named unit-tests-nxt.properties in the folder test/java under the Ardor project root folder and add to a single line of text starting with # or keep the file completely empty. The ContractRunnerSuite should run now with a few failures and you can add your own unit tests. Of course we will fix these problems for the next release.
