To use Apache Maven with J-Link you have to upload the pfc.jar and/or the pfcasync.jar in you local repository:
Go to <maven-installation-path>/bin an execute the command:
mvn install:install-file -Dfile=<proEngineer-installation-path>\text\java\pfcasync.jar -DgroupId=com.ptc.proe -DartifactId=ptcproe -Dversion=Wildfire_3.230_64Bit -Dpackaging=dll -DgeneratePom=true
The options DgroupId, DartifactId, and Dversion are examples. Importent is that you set the option Dpackaging to dll otherwise you will have problems to load the necessary dll's.
Additional:

mvn install:install-file -Dfile=<ProductView API-install path>\java\jar\pview.jar -DgroupId=com.ptc.productview -DartifactId=ptcpv -Dversion=9.1.M030 -Dpackaging=jar -DgeneratePom=true
