FormScanner uses sone libraries that are not available in any maven repository so you have to install it locally.
In the project fomscanner-commons into the src/main/resources/lib folder you can find the external libraries.
For install the libraries in the local repository tou can type these command from command line:
mvn install:install-file -Dfile=c:\..\quaqua-8.0.jar -DgroupId=ch.randelshofer
-DartifactId=quaqua -Dversion=8.0 -Dpackaging=jar
mvn install:install-file -Dfile=c:\..\formscanner-utils-1.0.jar -DgroupId=com.albertoborsetta
-DartifactId=formscanner-utils -Dversion=1.0 -Dpackaging=jar
mvn install:install-file -Dfile=c:\..\jfxrt-2.2.79.jar -DgroupId=com.oracle
-DartifactId=javafx -Dversion=2.2.79 -Dpackaging=jar
Formscanner-utils and javafx libraries are not used in formscanner (I have introduced them while trying to use JavaFX for the User Inteface) and I think I will remove them in the next release.
Quaqua.jar is a SWING library for adapt the GUI to Mac LookAndFeel.
