@oscerd, @zhfeng Ready for review , thanks :-)

We have the same problem as before, we cannot include the lib and we cannot build in this way. We should remove even the other example, because we cannot have a way to include the library and build

@oscerd If i change it as provided as below, will it be O.K solution for you?

mvn install:install-file -DgroupId=com.github -DartifactId=com.sap.conn.jco.sapjco3 -Dversion=3.0.11 -Dpackaging=jar -Dfile=lib/sapjco3.jar 
mvn install:install-file -DgroupId=com.github -DartifactId=com.sap.conn.jco.sapidoc3 -Dversion=3.0.11 -Dpackaging=jar -Dfile=lib/sapidoc3.jar

We need to find a way to fully build, so we need to update the modules list and check.
