= Developing GWT Applications with Maven =

 * pack gwt-dev-(OS Name).jar with library files, then create gwt-dev-(OS Name)-(version).jar archives
   * *.dll (windows)
   * *.jnilib (mac)
   * *.so  (linux)
 * source:trunk/archive/gwt/dev

 * Deploy the archives into the maven repository
{{{
leo@leopardcat:utgb/utgb-core> mvn deploy:deploy-file -Dfile=$(cygpath -w ~/work/utgb/trunk/archive/gwt/dev/gwt-dev-windows-1.4.60.jar ) -DgroupId=com.google.gwt -DartifactId=gwt-dev-windows -Dversion=1.4.60 -Dpackaging=jar -DrepositoryId=utgb -Durl=file://f:/cygwin/home/leo/work/workspace/utgb/maven/artifact 
}}}


 * gwt-dev-(windows,mac,linux).jar and the other dependent libraries will be downloaded from:
    * http://www.xerial.org/maven/artifact/com/google/gwt
    * http://www.xerial.org/maven/artifact/org/xerial/maven/gwt-ant

 * pom.xml 
   * use the following setting within build/plugins tag

 * utgb-common's pom.xml contains the following setting, that retrieves gwt-dev libraries.
