Spring-Boot and scala cannot find main class - spring

Question

I am trying to make a simple hello world web application in Scala which bootstraps spring-boot as its framework using maven as build tool.
I looked around a bit (there are a few tutorials with Gradle and much less information with maven, is there a reason for it?)
I Managed to get everything wired up but now i am stuck with this error when trying to run the application:
Error: Could not find or load main class SampleWebApplication
Here is the source code,
parent pom from github removing some code about git and deployment leaving the structure intact
Then my web application pom:
<parent>
<groupId>X.Y.Z</groupId>
<artifactId>spring-boot-scala-app-parent</artifactId>
<version>1.0.5-SNAPSHOT</version>
</parent>
<artifactId>webservice</artifactId>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.1.3.RELEASE</version>
<configuration>
<mainClass>SampleWebApplication</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
SampleWebApplication:
import org.springframework.boot.SpringApplication
class SampleWebApplication extends App {
SpringApplication.run(classOf[SampleConfig]);
}
SampleConfig:
#Configuration
#EnableAutoConfiguration
#ComponentScan
class SampleConfig {
}
