Hi @NehaCMS , first off you need to get rid of all the SCR annotations and replace them with OSGi R6/R7 annotations. Post that your build will probably not fail.

Thanks,

Hi @bilala23933647 - What about maven-surefire-plugin error 07:59:56,450 [main] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on : Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test failed: has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 -> [Help 1] Kindly update on same as well

Hey @NehaCMS you can either try this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.2</version>
    <configuration>
        <testFailureIgnore>true</testFailureIgnore>
    </configuration>
</plugin>

or
add -DskipTests while building the project using maven. If running the jUnit test are necessary, I'd want to know what package are you using ? is it 

import org.junit.Test;

or

import org.junit.jupiter.api.Test;

if the earlier one, try replacing it with the latter.

Thanks,

Bilal.
