Pela mensagem de erro o problema é que não está executando nenhuma aplicação web.

No build deu essa mensagem:

remote: -----> Discovering process types
remote:        Procfile declares types -> (none)

mas deveria ter dado types -> web:

Você colocou o plugin no seu pom.xml?

</plugin>

Além desse plugin, precisamos criar um arquivo que é requerido pelo Heroku para indicar como a nossa aplicação será executada quando esta for inicializada no servidor. Este arquivo deve se chamar Procfile e deve conter o seguinte conteúdo:

web: java $JAVA_OPTS -jar -Dspring.profiles.active=prod target/dependency/webapp-runner.jar --port $PORT target/*.war
