This following error is caused when the JAR is not generated.
The solution for this is that the user has to go to this particular directory:
~/workspace/<>-ME_QMONEY
and execute the command
./gradlew publishToMavenLocal
The above command generates a JAR based on the logic provided in your QMONEY directory.
Then the user can come back to the annual-return-app directory:
and execute the following command:
./gradlew build bootrun
And wait for the server to load.
