Let me suggest the following things in order to make the online build assessment a bit easy for you for this as well as the upcoming modules.
Try to follow the following things
Suggestion 1: Try to run build locally before pushing your code by the following commands ./gradlew build
and ./gradlew test
Suggestion 2: Try to debug code, there are very good tutorials available online
, I would like to give you one link which helped me a lot
Link
https://code.visualstudio.com/docs/java/java-debugging
Suggestion 3: You’ll be dealing with lint/checkstyle errors frequently in the upcoming modules, so I suggest you read about what is Linting and how to resolve them.
Suggestion 4: I suggest you not to make any guesses on resolving a particular error
, each line of code has a unique personality in it, so what you should do is search for the tutorials about the concept and try to gauge how the stuff is working.
Suggestion 5: Try to learn GIT commands functionalities, like sometime we use those commands but dont know the functionality of them. So its always better to know how the commands stuff is working internally, to get a sure shot and sharp picture.
Hope you’ll have a good experience in the upcoming modules 
Happy coding
