1. Change to the ucar directory.

   cd  idv

2. Execute the ant command to build clean idv.

   ant  clean idv

   This removes all Java class files (there will be none the first time), re-builds them.
3. To run the IDV using your build use:

   java  -Xmx1024m  ucar.unidata.idv.DefaultIdv

4. For the purposes of this workshop, we've created an alias so you can just type:

   idvdev

5. List out the CLASSPATH we have set up for you:

   set | grep CLASSPATH
