Fat JAR for NetBeans

[gmail Vladimir Koković <vl...@gmail.com>]

If one needs to distribute only one jar without dist/lib jars, the 
following ant script segment should be inserted after the line <import 
file = "nbproject/build-impl.xml" /> in the project build.xml:

     <!--
       This is original "Fat JARs out of NetBeans" for NetBeans 6.8 link:
https://busyprogrammer.wordpress.com/2010/01/26/fat-jars-out-of-netbeans/
       For newer Netbeans it is necessary to change:
       <target 
depends="init,compile,-pre-pre-jar,-pre-jar,-unjar-and-copy-lib-jars" 
name="fat-jar">
       into
       <target depends="-do-jar,-unjar-and-copy-lib-jars" name="fat-jar">
     -->
     <target name="-unjar-and-copy-lib-jars">
       <!--
         If the ant reports you a 'Cannot fix dependencies for:' message,
         the following 2 lines allow you to overcome the jar problem 
that is in the message:
         <copy file="problematic.jar" todir="dist/lib" overwrite="true"/>
         <echo level="info">Copied problematic.jar to dist/lib</echo>
       -->
       <unjar dest="${build.classes.dir}">
         <fileset dir="dist/lib">
           <include name="**/*.jar"/>
         </fileset>
         <patternset>
           <exclude name="META-INF/**"/>
           <exclude name="/*"/>
         </patternset>
       </unjar>
     </target>
     <target depends="-do-jar,-unjar-and-copy-lib-jars" name="fat-jar">
       <property location="${build.classes.dir}" 
name="build.classes.dir.resolved"/>
       <jar destfile="${dist.jar}">
         <fileset dir="${build.classes.dir}"/>
         <manifest>
           <attribute name="Main-Class" value="${main.class}"/>
         </manifest>
       </jar>
       <echo>To run this application from the command line without Ant, 
try:</echo>
       <property location="${dist.jar}" name="dist.jar.resolved"/>
       <echo>java -jar "${dist.jar.resolved}"</echo>
     </target>
     <target depends="clean,fat-jar" name="clean-and-fat-jar"/>


The inserted targets are called as follows:
Files-> build.xml-> Run Target-> Other Targets-> clean-and-fat-jar
or
Files-> build.xml-> Run Target-> Other Targets-> fat-jar

The result of these targets is dist/${dist.jar} and as mentioned above, 
only that jar is distributed.

Nice. Sounds like a tip you might want to share on Twitter, etc, pointing
here. :-)
