Combine all the jar into one JAR

[EricMacau]

Hello,

Is there any function in NetBeans 6.1 to combine all the JAR library
into one JAR?

Best regardrs,
Eric

Interesting question: unfortunately I don't know.

Manually, you could unpack all your JARs to the same folder, and than JAR/ZIP
the contained files to one JAR file.

But of course this is not comparable to NB's helpful automatic JAR file
generation...

Remember that merging JARs can be explicitly prohibited by some  
licenses. For instance, I believe that this practice is prohibited by  
GPL and LGPL.

OK.
However for my own library JARs, which I share between several projects, I'd
wish to be able to make NB merge them into one JAR. Is this possible, somehow?

To achieve a sort of automation you can override the -post-dist target
in the project build.xml file.
For example:

<tempfile property="unpack.temp.dir" prefix="unpack" suffix=""/>

<target name="-post-dist" depends="unpack-jars, merge-jars"/>

<target name="unpack-jars">
        <mkdir dir="${unpack.temp.dir}"/>
        <unzip src="${jar1}" dest="${unpack.temp.dir}"/>
        <unzip src="${jar2}" dest="${unpack.temp.dir}"/>
        <unzip src="${jar3}" dest="${unpack.temp.dir}"/>
        ...
</target>

<target name="merge-jars">
        <jar jarfile="${my.big.jar}">
                <zipfileset dir="${unpack.temp.dir}"/>
        </jar>
        <delete dir="${unpack.temp.dir}" quiet="true" includeEmptyDirs="true"/>
</target>
