Compiling from Source
Checking Out the Source from Subversion
Checking out the GWT-Ext source is most useful if you plan to compile GWT-Ext yourself. The pre-built GWT-Ext distribution already contains all the Java source, so you don't actually need to check it out from the repository just to debug through it. Just tweak your IDE to read source from the GWT-Ext jars.
GWT-Ext is hosted on Google Code project hosting, so you check out the source for GWT-Ext using a Subversion client as you would for any other project hosted on Google Code:
svn checkout http://gwt-ext.googlecode.com/svn/trunk/ trunk
The project source code access page has additional instructions for browsing the source online or getting a Subversion client if you don't already have one.
Here's a good writeup if you're using Eclipse : http://wiki.oreade.nl/Wiki.jsp?page=GwtExtSubversionDownloadCompile.
Compiling from Source
Everything is Java source that can be built with the included GWT-Ext Ant build files.
Install Ant 1.6.5 http://ant.apache.org/bindownload.cgi or later. We'll assume that the ant command is in your path.
Check out the GWT-Ext prerequisite tools and third-party libraries:
~/gwt-ext$ svn checkout http://gwt-ext.googlecode.com/svn/tools/ tools
Check out the GWT-Ext source:
~/gwt-ext$ svn checkout http://gwt-ext.googlecode.com/svn/trunk/ trunk
Switch to the directory into which you checked out the GWT-Ext source. Let's assume you checked it out into ~/gwt-ext/trunk. Make sure you're in that directory..
~/gwt-ext$ cd ~/gwt-ext/trunk
then just invoke Ant
ant
The GWT-Ext build creates a binary distribution in the build/dist subdirectory of the source root directory. In this example, the distributions would be in ~/gwt-ext/trunk/build.
Testing
To perform the tests, simply run
ant test
and verify that there are no failures.
Ant JUnit Issues
There is a problem, detailed at ant.apache.org, where ant cannot find the JUnit classes. The simple workaround is to either:
Delete ant-junit.jar from the ant lib directory (for example, /usr/share/ant/lib/) Copy junit.jar into your ant lib directory
Ant XSLT issues
If you get an error like the one below, please remove the file {ANT_HOME}\lib\xercesImpl.jar from your Ant installation as the copy of Xerces distrbuted with certain versions on Ant causes conflicts.

Precisely, you will need to:
~/gwt-ext/tools/lib/gwt/1.4.60/mac$ cp -p ~/gwt-mac-1.4.62/gwt-*.jar . ~/gwt-ext/tools/lib/gwt/1.4.60/mac$ cp -p ~/gwt-mac-1.4.62/lib*.jnilib .
You will also need to unzip Ext 2.0.2 to ~/gwt-ext/tools/lib/ext/2.0.2 - et voilà ! :)

Hi Sanjiv,
I'm really happy that you refer to the wiki about compiling using Eclipse, i have moved my site to a new location (the other one will soon be taken down). I would appreciate it if you could change the url:

The upper instructions only work if your OS is Windows. This will not work under Mac with the current Ant script (as it looks for the path tools/lib/gwt/1.4.60/mac and you only get the windows one while performing svn checkout tools). Creating the mac directory and moving there the Mac specific libraries will solve the problem.
