Error 43 if jar already exists?

[Tom Corcoran]

I am building a jar including my <classes> directory. I need to roll up
the content of another directory, <image> which is at the same level as
<classes> and include the directory name in the jar.

 

  <property name="build" location="classes"/>

  <property name="dist"  location="jar"/>

  <property name="image"  location="image"/>

 

<target name="dist" depends="compile"

        description="generate the distribution" >

    <jar jarfile="${dist}/MyApplet.jar" basedir="${build}">

    </jar>

   

    <jar jarfile="${dist}/ MyApplet.jar" basedir="." update="True">

      <include name="**/image/*.*"/>

    </jar>    

  </target>

 

This works if the jar does not already exist but if it does I get a
weird error : 43 unable to rename old file (my jar) to temporary file.
How do I get around this? Or perhaps there is a better way of doing my
build. Note, basedir="." Contains lots of other directories I do not
need in the build.

 

Thanks,

 

Tom.
