I just unzipped the eclipse ganymede (eclipse 3.4.1) zip file (basic platform) and tried to install Webtools (WTP) via its update site. But it reports an error like ..
Cannot complete the request. See the details.
WST Common UI is already installed, so an update will be performed instead.
WST Common Core is already installed, so an update will be performed instead.
WST XML Core is already installed, so an update will be performed instead.
WST XML User Documentation is already installed, so an update will be performed instead.
Eclipse XML Editors and Tools is already installed, so an update will be performed instead.
Cannot find a solution where both Match[requiredCapability: org.eclipse.equinox.p2.iu/org.eclipse.jpt.doc.isv/[1.1.0.v200812110000,1.1.0.v200812110000]] and Match[requiredCapability: org.eclipse.equinox.p2.iu/org.eclipse.jpt.doc.isv/[1.0.0.v200805220000,1.0.0.v200805220000]] can be satisfied.

回答1:
Have you already looked at this?
http://www.eclipse.org/webtools/faq/GettingSource/
There are different instructions for putting the WTP on Ganymede than the other versions of Eclipse.
回答2:
Did you also let it search the Ganymede site at the same time?
