Error Creating DataSource Postgres in Spring Boot

Question

I'm getting this error when trying to run the application in eclipse (Run as> Java Application):

Caused by: org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.
at org.springframework.boot.autoconfigure.jdbc.DataSourceProperties.getDriverClassN ame(DataSourceProperties.java:137)

But when I run in the command window ( mvn spring-boot:run) it runs perfectly.

Application.properties:

spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
spring.database.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/gafanhotator
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.thymeleaf.cache=false

It's very odd, I already tried in STS too, same error. Any ideas?

Answer 1

I don't know how and why but in my Java Build Path in the Source "src/main/resources" it was setted to exclude all *.java, *.yaml and *.properties files. I just exclude those patterns and all worked out great.

Is this a eclipse default somehow?
