Unable to use Intellij with a generated sources folder

Question

Related question How to configure IntelliJ IDEA and/or Maven to automatically add directories with Java source code generated using jaxb2-maven-plugin?

I have a custom plugin that generates sources under target/generated-sources (Note no toolname here). So I get sources like target/generated-sources/com/mycompany...etc.

This format cannot be changed at all, so will I be able to configure Intellij into adding it as a source folder. As of now, I can see that Intellij has added target/generated-sources/com as the source folder.

Please note that I do not have the option of configuring the plugin !

UPDATE 1: I do not agree with the fact that I MUST put my generated sources under a tool name folder. It may be a good convention, but if I have only one generator there is no need for me to put it there? Again, in my pom.xml I have a resources section which clearly indicates that target/generated-sources should be treated as a source folder. This works perfectly fine in Eclipse so I have no idea why Intellij would not respect my settings.

TL;DR -> When I put target/generated-sources in the resource section of pom.xml why is Intellij overzealous to add target/generated-sources/com to the classpath?

You can just change the project structure to add that folder as a "source" directory.

Project Structure → Modules → Click the generated-sources folder and make it a sources folder.

Or:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>build-helper-maven-plugin</artifactId>
    <version>1.4</version>
    <executions>
        <execution>
            <id>test</id>
            <phase>generate-sources</phase>
            <goals>
                <goal>add-source</goal>
            </goals>
            <configuration>
                <sources>
                    <source>${basedir}/target/generated-sources</source>
                </sources>
            </configuration>
        </execution>
    </executions>
</plugin>
