How to set multiple source locations in Sonar Server?

I'm using Maven 3 and in my java project, the pom file contains one source location as follows.

<build>
        <sourceDirectory>src/main/java</sourceDirectory>
        <testSourceDirectory>src/test/java</testSourceDirectory>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>${JDK}</source>
                    <target>${JDK}</target>
                    <excludes>
                        <!--<exclude>**/**/api/notification/**/INotificationProfileManager.java</exclude> -->
                    </excludes>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-ejb-plugin</artifactId>
                <configuration>
                    <version>1.3</version>
                    <archive>
                        <manifest>
                            <addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
                            <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                        </manifest>
                        <manifestEntries>
                            <Class-Path>./MubarsherTradeClasspath-1.0.jar</Class-Path>
                            <Specification-Vendor>Mubasher</Specification-Vendor>
                            <Implementation-Vendor>Mubasher</Implementation-Vendor>
                            <Sealed>false</Sealed>
                        </manifestEntries>
                    </archive>
