Module path can't be defined

[Lawyer1990]

Hello!
The problem is in module path. When plugin run main class, which is in module it defines the root path. Therefore, I can't use files in module because the path there isn't correct.

Actual result:
The path file in module is C:/RunTests/src/main/resources/text.txt

Expected result:
The path file in module is C:/RunTests/ModuleOne/src/main/resources/text.txt

Not sure if it is possible, but I would like the possibility to define a specific execution ID in a submodule and then target that from the command line:

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>my-target</id>
                        <goals>
                            <goal>java</goal>
                        </goals>
                        <configuration>
                            <mainClass>...</mainClass>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

> mvn exec:java@my-target

Currently exec:java is attempted for all modules, incl. the root reactor, and generally fails for not having mainClass defined:

The parameters 'mainClass' for goal org.codehaus.mojo:exec-maven-plugin:3.1.1:java are missing or invalid

Even when I define default <skip>true</skip> for my my-target execution in the root POM (then override for the submodule execution):

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>my-target</id>
                        <goals>
                            <goal>java</goal>
                        </goals>
                        <configuration>
                            <skip>true</skip>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

it fails for not having mainClass defined. I've worked it around by defining an empty default in the root POM:

    <properties>
        <exec.mainClass />
    </properties>

This could result in a suboptimal experience with other exec:java usages – confusing error message with mainClass really not defined.
