AEM 6.1 java 1.8 compatibility issue

Hi,

we are trying to upgrade our project to AEM 6.1 and JDK 1.8 version . 

we are trying to modify the pom.xml files of my project. 

we used  the following combinations :

<plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <version>3.1</version>
                    <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
                </plugin>

<plugin>
                    <groupId>org.apache.felix</groupId>
                    <artifactId>maven-scr-plugin</artifactId>
                    <version>1.21.0</version>
                    <extensions>true</extensions>
                     <configuration>
                    <sourceExcludes>com/sapient/archive/*.java</sourceExcludes>
                </configuration>               
                    <executions>
                        <execution>
                            <id>generate-scr-scrdescriptor</id>
                            <goals>
                                <goal>scr</goal>
                            </goals>
                            
                        </execution>
                    </executions>
                </plugin>

<dependency>
            <groupId>org.apache.felix</groupId>
            <artifactId>org.apache.felix.scr.annotations</artifactId>
            <version>1.9.6</version>
            <scope>provided</scope>
        </dependency>

if we use the following combination in parent and as well and child we are getting the following error: 

[ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.21.0:scr (generate-scr-scrdescriptor) on project aem.foundation: SCR Descriptor parsing had failures (see log) -> [Help 1]

if we use the above combination only in parent, build got the success, but generated jar file is not creating OSGI-INF folder . 

can anyone please provide the sample pom.xml file which will both compatible with 1.7 and 1.8 . 

Thanks,
