Set up hot reload with parameters with Maven and Spring

I have a maven generated project. This is my pom.xml:

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

I build it using this command:

@mvn package -PLOCAL

And run using this command:

java -jar -Dspring.profiles.active=rganeyev target/abacus-web-0.1.jar

I have an src/main/resources/application-rganeyev.properties file, where my local properties are set. The application must use this file to work properly.

It works fine, build and running goes ok. The problem is I can not use hot reloading. Documentation says:

Developer tools are automatically disabled when running a fully packaged application. If your application is launched from java -jar or if it is started from a special classloader, then it is considered a “production application”.

To use hot-reloading, I mustn't use java -jar, but only mvn utilities. I tried to run mvn spring-boot:run -PLOCAL -Dspring.profiles.active=rganeyev, but it does not use properties file and crashes. Hot to run maven and use my properties file?

Hi try to add the profile definition to the POM.

<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
            <profiles>
                <profile>rganeyev</profile>
            </profiles>
        </configuration>
    </plugin>
</plugins>

And than call it with the profile:

mvn spring-boot:run -Dspring-boot.run.profiles=rganeyev
