Two gradle tests are failing (during ./gradlew test and ./gradlew build)

[martocci]

I am trying to install the http-step on a GCP Compute Engine. Any assistance would be helpful. I cloned the repo and am trying to run ./gradlew test OR ./gradlew build. They both fail because of failing tests. Other rundeck repos (like the kubernetes plugin) have built without issue. Thanks!

OS version: Debian GNU/Linux 9 (stretch)
Java SDK version: openjdk version "1.8.0_232"

Tests that fail:
edu.ohio.ais.rundeck.util.OAuthClientTest > canHandleInvalidCredentials FAILED
java.lang.Exception
Caused by: java.lang.NullPointerException at OAuthClientTest.java:190
edu.ohio.ais.rundeck.util.OAuthClientTest > canHandleInvalidToken FAILED
java.lang.Exception
Caused by: java.lang.NullPointerException at OAuthClientTest.java:196
26 tests completed, 2 failed
