```xml
	
	<dependencyManagement>
 	   <dependencies>
			
     	 <dependency>
        	  <groupId>org.springframework.boot</groupId>
        	  <artifactId>spring-boot-devtools</artifactId>
         	 <scope>runtime</scope>
         	 <optional>true</optional>
     	 </dependency>
   	 </dependencies>
	</dependencyManagement>
	
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                </configuration>
            </plugin>
        </plugins>
    </build>
```
