What ant version are you running?  This error looks like Ant failing to find 
the right class.

Assigning to Freeland, I think he wrote the build.properties.

To make it work in ubuntu, I had to use a ppa installer to get java7 setup 
right http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html

Also make sure you set JAVA_HOME and ANT_HOME in .bashrc.

And you should also check ant -version as well.  <1.8.4 = no go.

Should be fixed now.

As suggested, I pinned to ant 1.8... we are using the "javac1.7" word 
(introduced in ant 1.8.2, though we could have instead used "modern" as its 
synonym).  But in practice I think we all have been using 1.8.2-or-4, and 
pinning seems to avoid any such confusions in the future.

As a side note, however, anything in build.properties can be overridden by 
creating your own local.properties, and setting it there, so (previously) if 
you wanted to use ant 1.7, you could have set javac.compiler=modern there, and 
I think it would have worked... unless there is some other dependency, which I 
hadn't noticed, and that possibility is why I agreed to pin it.

Side fix in the same update, "ant clean" will now recreate the generated source 
directories, which helps keep Eclipse from whining if they go mis sing.
