How to use maven profile and overlays to build and package with specified project from multiple?

问题

I have one web project called MyWebProject which having sub modules also and packaging as POM, I have other two simple java project called SimpleJavaProject1 and SimpleJavaProject2 which having packaging as JAR.

I am having dependency for both in web peoject. So I have to use Maven Profile and Overlays such way, that when I will build and package my web project with profile JavaProject1 then web project includes SimpleJavaProject1 in its war and when I said JavaProject2 then it should include SimpleJavaProject2. And it should use Overlays only for specified java project.

Can I use Overlays in Profile?

Please suggest some idea if any...

I'm not familiar with overlays, but hopefully this approach will work for them too.

Typically one solves this sort of problem by defining a property in your parent POM, based on the profile:

<profiles>
    <profile>
        <id>JavaProject1</id>
        <properties>
          <java.project>SimpleJavaProject1</java.project>
          <java.project.version>1.1</java.project.version>
        </properties>
    </profile>
    <profile>
        <id>JavaProject2</id>
        <properties>
          <java.project>SimpleJavaProject2</java.project>
          <java.project.version>1.2</java.project.version>
        </properties>
    </profile>
</profiles>

Then use this property when you define your dependency (and hopefully your overlays too):

<dependency>
    <groupId>com.foo</groupId>
    <artifactId>${java.project}</artifactId>
    <version>${java.project.version}</version>
</dependency>

Got it...referring @Duncan answer I have tried following and its worked. :-)

Following are my Profiles,

<profile>
    <id>JavaProject1</id>
    <properties>
        <roject.groupId>mygroupId</project.groupId>
        <roject.artifactId>myartifactId</project.artifactId>
        <roject.version>${myversion}</project.version>
    </properties>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
</profile>

<profile>
    <id>JavaProject2</id>
    <properties>
        <roject.groupId>mygroupId</project.groupId>
        <roject.artifactId>myartifactId</project.artifactId>
        <roject.version>${myversion}</project.version>
    </properties>
    <activation>
        <activeByDefault>true</activeByDefault>
    </activation>
</profile>

And I have added Overlays in war plugin as follows,

<overlays>
    <overlay>
        <groupId>${project.groupId}</groupId>
        <artifactId>${project.artifactId}</artifactId>
        <type>jar</type>
        <targetPath>WEB-INF/classes</targetPath>
    </overlay>
</overlays>

It worked successfully. :-)
