See https://developers.google.com/eclipse/docs/faq#wstinstallerror
You have to install WST first, and then you'll be able to install the Google Plugin for Eclipse.
回答2:
This message generally says that there are problems when trying to connect to Helios update server. Because when installing GWT, you need extra package from it.
I met the similar(same ?) problem with Luna 64bit eclipse, when trying to install Google Plugins for Eclipse. This is solution I suggested: 1. Go to Preferences -> Install Update -> Available Software Update. 2. Delete Helios entry. Quit eclipse. Make sure your network is ok. Reopen eclipse. Go back and re-add Helios entry. Click reload. 3. If no Helios entry is found in step 2, then simply add it and no need to do the else.
