we need modify project.version in pom.xml when we merge source code from 
develope branch to master branch in git. it‘s troublesome!

So I expect that project.version in pom.xml can reference a property 
(build-version) in <propfiles>, and I can't set different version property 
value In different profiles 


{code:xml}
<project ... >
    <modelVersion>4.0.0</modelVersion>
    <groupId>org.example</groupId>
    <artifactId>example</artifactId>
    <version>${project-version}</version>
    <packaging>jar</packaging>

    <properties>
        <project-version>1.0.0-SNAPSHOT</project-version>
    </properties>

    <profiles>
        <profile>
            <!-- snapshot -->
            <id>dev</id>
            <properties>
                <profiles.active>dev</profiles.active>
                <project-version>1.0.0-SNAPSHOT</project-version>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <!-- RELEASE -->
            <id>release</id>
            <properties>
                <profiles.active>release</profiles.active>
                <project-version>1.0.0-RELEASE</project-version>
            </properties>
        </profile>
    </profiles>
  
</project>
{code}
