Spring-boot config server application throw exception

Question

I am running simple demo of spring cloud config server on Mac OS X. Application has native as active profile and use local folder for config files instead of git. When I launch application it throws exception:

I ran similar example on windows 7 machine in my workplace and it worked fine. Does anyone have any idea what could be problem?

Thanks

Answer 1

Generally when those kind of errors pop up something went wrong when maven downloaded the dependencies. To solve this clear your local repository from the borked dependencies.

You have basically two ways of solving this

1. Bluntly remove the full ~/.m2/repository directory, removing all local dependencies
2. The more subtle mvn dependency:purge-local-repository to remove all project dependencies from the ~/.m2/repository directory.

After that just rebuild your application mvn package to download the dependencies again.

Answer 2

In the last line of application.yaml use searchLocations instead of search-locations.
