Maven java classes generated in “target” folder are not compiled

Question

I have a plugin which generates lots of java files (ie FileA.java, FileB.java) under target folder. I'm using "exec-maven-plugin" to execute my plugin as follows

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>generate-event-beans</id>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>java</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.my.project.generate.GenerateJavaFiles</mainClass>
                        <classpathScope>compile</classpathScope>
                        <arguments>
                            <argument>${basedir}/src/main/resources</argument>
                            <argument>${project.build.directory}/generated-sources/generated</argument>
                        </arguments>
                    </configuration>
                </execution>
            </executions>
        </plugin>

I want to compile these java files created under ${project.build.directory}/generated-sources/generated without adding them to source and package them in jar

With maven-compiler-plugin you can add your files to the build without adding them to src folder.

Example from doc :

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <includes>
      <include>...</include>
    </includes>
  </configuration>
</plugin>
