Setup

This demo project has 3 modules:

• module1 (declared as shared module)
• module2 (depends on module1)
• module3 (depends on module1 and module2)

Case 1

Run ./gradlew test

Result: test ApplicationArchUnitTest that verifies modules passed

Case 2

Run ./gradlew bootRun

Result: service starts

Case 3

Run ./gradlew assemble && java -jar build/libs/demo-0.0.1-SNAPSHOT.jar

Expected result: service starts (as in case 2)

Actual result: service does not start with the following exception:

java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Module module1 does not exist!
