Answer 1

Resolved!

Problem was not with the weblogic server, the problem was, I had my source code in separate folder instead of src, so weblogic was not able to find package to scan in src folder, after adding below plugin in pom.xml, deployment was successful -

<plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>3.0.2</version>
   <executions>
      <execution>
         <id>copy-source</id>
         <phase>generate-sources</phase>
         <goals>
            <goal>copy-resources</goal>
         </goals>
         <configuration>
            <outputDirectory>co/src</outputDirectory>
            <overwrite>true</overwrite>
            <resources>
               <resource>
                  <directory>${basedir}/co/EBP</directory>
               </resource>
            </resources>
         </configuration>
      </execution>
   </executions>
</plugin>

This plugin copies my source code to src folder with overwrite as true. Hence made source code available in src folder.

This problem could also be resolved by adding source folder in .classpath file.
