Below is my project structure:

Below are the contents of pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

                        <configuration>
                            <tasks>
                                <copy file="${basedir}/META-INF/services/abc.px" tofile="${project.build.directory}/META-INF/services/abc.px" />
                                <copy file="${basedir}/META-INF/services/xyz.px" tofile="${project.build.directory}/META-INF/services/xyz.px" />
                            </tasks>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>abc</groupId>
            <artifactId>abc</artifactId>
            <version>936</version>
            <scope>system</scope>
            <systemPath>path</systemPath>
        </dependency>
    </dependencies>
</project>

When I'm trying to compile using mvn compile it creates a target folder.

ex - target/classes/com/hcc

How can I include META-INF folder as it is while creating package i.e mvn package, so that my jar file includes target folder files and META-INF folder as it is?

In the build section of your pom.xml, under the maven war plugin declaration you can add the necessary configuration in which you specify your web resource as a directory and it's output path too:

       <plugin>
            <artifactId>maven-war-plugin</artifactId>
            <groupId>org.apache.maven.plugins</groupId>
            <version>${maven-war-plugin.version}</version>
            <configuration>
                <webResources>
                    <resource>
                        <directory>META-INF</directory>
                        <filtering>true</filtering>
                        <targetPath>META-INF</targetPath>
                    </resource>
                </webResources>
            </configuration>
        </plugin>

Or by adding it as a resource directly under build :

<build>
   ....
   <resources>
        <resource>
            <directory>META-INF</directory>
        </resource>
    </resources>
</build>
