I can across a tutorial of the same title as above, which as you can imagine will help extend social office (http://www.liferay.com/community/wiki/-/wiki/Main/Building+the+Social+Office+Trunk+using+the+Liferay+IDE).
However, the part of the tutorial that recommends you build the "all" target in build.xml of the liferay portal source keeps failing. See trace of error displayed below:
