If you are building your artifacts outside of Maven you need to reference them in your .pom file

At first, set the packaging of your project to pom so Maven will not attempt to compile anything.

Then use the build-helper-maven-plugin to attach your artifact files to the project. Here is an example:

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>build-helper-maven-plugin</artifactId>
        <version>1.8</version>
        <executions>
            <execution>
                <id>attach-artifacts</id>
                <phase>package</phase>
                <goals>
                    <goal>attach-artifact</goal>
                </goals>
                <configuration>
                    <artifacts>
                        <artifact>
                            <file>build/xbnjava-0.1.1/download/mylibrary-0.1.1.jar</file>
                            <type>jar</type>
                        </artifact>
                        <artifact>
                            <file>build/xbnjava-0.1.1/download/mylibrary-0.1.1-javadoc.jar</file>
                            <type>jar</type>
                            <classifier>javadoc</classifier>
                        </artifact>
                        <artifact>
                            <file>build/xbnjava-0.1.1/download/mylibrary-0.1.1-sources.jar</file>
                            <type>jar</type>
                            <classifier>sources</classifier>
                        </artifact>
                    </artifacts>
                </configuration>
            </execution>
        </executions>
    </plugin>

Finally, add the distributionManagement section to your .pom file as specified here.

You can refer to my own Maven project setup at github which was created to upload manually built .jar files on Maven central.
