I'm a .NET developer, but for my current project I need to use Google Caja, a Java project. Uh-oh!

I've followed the guide at http://code.google.com/p/google-caja/wiki/RunningCaja on my windows machine, but can't get the program to run. The command line they suggest didn't word, so I cd'd into the ant-jars directory and tried to run plugin.jar:

D:\java\caja\svn-changes\pristine\ant-jars>java -cp . -jar pluginc.jar -i test.htm
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

        at com.google.caja.plugin.PluginCompilerMain.main(PluginCompilerMain.java:368)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.cli.ParseException

        ... 2 more

Whats that all about?

I've also tried file:///d:/java/caja/svn-changes/pristine/ant-jars/test.htm instead of test.htm as looking at the source it seems the file param is a Uri...

I've also tried running IKVM on pluginc and then not worrying about java, but that came up with the ClassDefNotFoundException too...

thanks!
