Spring Boot Packaging Error when multiple main methods exist

[dmfrey]

A Spring Boot application cannot be packaged when multiple classes contain a main method.

Here is a sample project that demonstrates the issue:
https://github.com/dmfrey/spring-boot-package-error

Desired outcome: The main method from a class decorated with @SpringBootApplication should be used by default, or when there are any other conflicts.

Nice idea!

@philwebb Would this be an issue in Boot itself or is it related to the maven and gradle plugins? If you can provide me some direction, I will take a look at resolving it.

This makes a lot of sense - this 'bug' has caught us a few times. Unannotated classes that have a Main method should be ignored.

@dmfrey The logic's all in MainClassFinder and is used by both the build plugins.
