java eclipse maven ejb maven-compiler-plugin

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project

I am a newcomer in Maven and I want to import my application to maven. I want to, as before, refer on classes in my ejb-project into my war-project. I have no errors in classes, but if I make maven install on my Parent project then my war-project give me this error:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project SportunionWARModule: Compilation failure: Compilation failure:

I would be happy if anyone could help me... Thanks in advice!

Solution

As you mentioned, the missing elements are present on your EJB module.

Therefore, you need to remove your EJB module as a dependency from your EAR and add it to your WAR module. In your WAR's pom.xml file, add the following:

<dependencies>
    (...)

    <dependency>
        <groupId>SportunionParent</groupId>
        <artifactId>SportunionEJBModule</artifactId>
        <version>${project.version}</version>
    </dependency>

    (...)
</dependencies>

Also, since the EJB module is now a dependency of your WAR, I believe there's no need for you to have an EAR. Maven will place your EJB module on the WEB-INF/lib of your WAR.
