Ao configurar no Spring Initializr , o projeto não realizava Build com problemas no POM .
Solução: Inserir em Properties (arquivo POM ) o seguinte : <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
Meu codigo final que compila ficou:
<properties>
<java.version>1.8</java.version>
<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>
