To compile you need to put junit4 ( http://www.junit.org/ ) into the lib/ dir. Then just call ant version 1.7+
(if you want to generate the java5 version pass -Djre5.dir="C:\Program Files\Java\jre1.5.0_15")

Note that you have to compile using a jdk 6, since there's a bug in the version 5 (can't
throw a generic)

To validate XML (needed for JUnit tests) you need to download http://java.net/downloads/msv/releases/msv.20090415.zip and
put msv.jar, relaxngDatatype.jar, xsdlib.jar and isorelax.jar in the classpath.

Google docs
-----------
jOpenDocument created documents should be compatible but (at least for spreadsheets) Google only accepts lower case automatic style names.
It also only supports lengths in centimetres (at least for column widths) but this is now the default for TableStyle.getWriteUnit().
