vaadin 6.3 ant build target

The vaadin source web page still has out-dated build instructions.
I tried:

vaadin/6.3/build>$ ant package-linux                                                                                                         
Buildfile: build.xml                                                                                                        

BUILD FAILED
Target "package-linux" does not exist in the project "Vaadin". 

Total time: 0 seconds

Looking at the following I realised that things have changed a bit:

$ ant -p
Buildfile: build.xml

Main targets:

 build              Build package required files, without packing them.
 compile-widgetset  Compiles the widgetset given as the first parameter
 package-all        Build public packages.                             
 package-jar        Create vaadin-x.y.z.jar file.                      
 package-jar-quick  Create vaadin-x.y.z.jar file quick.                
 test-build         used for testing build.xml                         
 test-package       used for testing build.xml                         
Default target: package-all                                            

So I tried the following starting building like crazy:

$ ant package-all                                                      
Buildfile: build.xml
...

But it got stuck on:

manual-checkout:
     [echo] Checking out manual from repository http://dev.vaadin.com/svn/doc/trunk
    [mkdir] Created dir: /stf/prj/fs/vaadin/6.3/build/checkout  

Finally I did:

$ ant package-jar

and the jar finally got built!

BUILD SUCCESSFUL
Total time: 10 minutes 49 seconds

Will try out package-jar-quick next...

This made me shout out complaints about ant (ask my co-workers) and fall in love with maven all over again.
