The attached are my settings for Gradle in Intellij. The problem here is that I can't run Junit tests by right-clicking but the same operation can be done using gradlew test. I can't seem to find the reason as to why this is happening.

Seems like you're not using Gradle to run your tests from IntelliJ. In that case, make sure that your classpath is set properly.

This screenshot is from AB3 but you should get the idea.
