Gradle build failed for empty project

Question

I just created a project in spring boot, the project is clean (zero changes) just created and at first I wanted to build it with the command: ./gradlew clean build , but the build does not go through I get: BUILD FAILED ( Task:test FAILED ) What went wrong: Execution failed for task ':test'. java.lang.IllegalStateException: Failed to load ApplicationContext What went wrong: Execution failed for task ':test'. java.lang.IllegalStateException: Failed to load ApplicationContext I have no idea why I'm getting an error in an application where I haven't modified anything yet. What could be the cause of this? How can I build this application?

Answer 1

I think you have default test and you dont have main method that starts application. Maybe you can write some code to provide spring application to boot. Main method is enough for you. contextLoads() method test the application context be up or not. You need configure datasource as well. In your stacktrace I can see that driver is missing.
