Some of google's service is blocked here,and I can't install google's plugin from update site.so where is to download plugin archive for eclipse 4.4?Currently,only archive for 4.3 is provide in google's official site.
Here you go: http://dl.google.com/eclipse/plugin/core/4.4/zips/gpe-e44-latest-updatesite.zip
I had to do a bit of URL fiddling to find that.
