Question

I have parent project with:

<modules>
    <module>../module1</module>
    <module>../module2</module>
    <module>../module3</module>
</modules>

and modules with

<parent>
    <groupId>com.cc</groupId>
    <artifactId>parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</parent>

Can I somehow specify, that if there are no src at ../module2/ load those module from repository instead fail with Caused by: java.io.FileNotFoundException: C:\work\temp\wid7\workspace\module2 (The system cannot find the file specified.)?

It’s possible to resolve problem via profiles.

<profiles>
    <profile>
        <id>module1</id>
        <activation>
            <file>
                <exists>../module1/pom.xml</exists>
            </file>
        </activation>
        <modules>
            <module>../module1</module>
        </modules>
    </profile>

    <profile>
        <id>module2</id>
        <activation>
            <file>
                <exists>../module2/pom.xml</exists>
            </file>
        </activation>
        <modules>
            <module>../module2</module>
        </modules>
    </profile>
    ...
</profiles>

Profiles concatenate modules block to one. So others modules got from repository.
