play2-maven with nonplay submodules

[mhmgad]

So I tried to create project with 3 submodules one is play and 2 are normal java modules and I made the main POM file as in play24/multimodule example .. Whenever I try to execute mvn play2:run it fail to execute run on other submodules. I added the plugin to all submodules but I get this mvn error

How can I fix that?

[gslowikowski]

Hi. Can you create test project? This will help me find the bug faster.

[lukoyanov]

@mhmgad you can add following section to your non play submodules pom.xml to fix it.

    <build>
        <plugins>
...
            <plugin>
                <groupId>com.google.code.play2-maven-plugin</groupId>
                <artifactId>play2-maven-plugin</artifactId>
                <version>1.0.0-rc1</version>
                <configuration>
                    <playVersion>${play2.version}</playVersion>
                    <runSkip>true</runSkip>
                </configuration>
            </plugin>
...
        </plugins>
    </build>

@gslowikowski Sorry for not setup a test project .. I just got busy! .. I will try to simulate the senario

@lukoyanov I added it but when I use mvn play2:run on the main project it gives success messages for all sub-modules as well as the play one and the server is not starting.

So my hierarchy is :

Parent (Maven)
|-- commons (java maven NOT play)
|--core (java maven NOT play)
|-- web-app (java maven play)

All of them has pom files that have Parent specified and core has depends on commons and they compile together peacefully. Finally, I added web-app and it has core as dependency and added it as module to Parent and declared it to be the main play2 module.

When I follow example multimodel in play24 test projects and use play2:run from the Parent, it just gives success messages and do not start the server as expected.

On the other hand, when invoking play2:run from inside web-service directory it searches for the core and commons in the local repository instead of compiling/packaging them from the Parent project. So, I have to install them first into my repo.

Thank you for your suggestion, I tried it but the result is the same

Edit: The problem is resolved ... <mainModule> is a misleading property name.. it should be main artifactID (play module artifactId) something like that because maven uses the folder names for <module>.

Sorry for disturbance !

@mhmgad Hello, I seem to be facing the same issue. How did you resolve it ? I dont find any property in the pom.xml. Any help is appreciated.
