Profiles in pom.xml doesn't work when i use "-P" command

Question

I have a pom.xml with profiles like this:

<profiles>
        <profile>
            <id>server1</id>
            <properties>
                <api.server.ip>serveraddr1</api.server.ip>
                <finalName>springboot</finalName>
            </properties>
        </profile>
        <profile>
            <id>server2</id>
            <properties>
                <api.server.ip>serveraddr2</api.server.ip>
                <finalName>springbootnew</finalName>
            </properties>
        </profile>
    </profiles>

And i am trying to use it to set variable and make the name of jar

public static final String IP_ADDR="${api.server.ip}";

But when i use the command "mvn clean package -Pserver2", it doesn't work at all, neither the variable is set, nor the jar is named correctly. And i find in IDEA it is like this: profiles in IDEA I didn't see "MyProfile" anywhere. And it still doesn,t work when i trying to use IDEA to select profile.

tried command "mvn clean package -Pserver2" and selecting profile in IDEA

You cannot use Maven profiles to read properties in your Java code. You can use them to filter resources that you can read in your Java code.

But as @M.Deinum already said, there are probably much better ways to achieve what you want to achieve.
