Install PDT 3.1.1 on Eclipse 3.7 (Indigo)

At first, when I tried to install PDT 3.1.1 on Eclipse 3.7 (Indigo), there was an error that a dependency software missing: DLTK 4.0.

It recalled me about the similar issue when I tried to install ShellED, a bash editor plugin of Eclipse, last month.

While I couldn't update DLTK from Indigo repository:

  http://download.eclipse.org/releases/indigo/

Or

  http://download.eclipse.org/technology/dltk/updates/

But there's a link for the nightly build on DLTK's page http://www.eclipse.org/dltk/install.php

I tried this link in Eclipse install new software dialogue window, this time it returned all DLTK 4.0 packages, wonderful!

After DLTK 4.0 installed, just install PDT 3.1.1 via this source in the installation dialogue:

  http://download.eclipse.org/tools/pdt/updates/release

and finally, as a frosting on the cake, I installed ShellED via this soource:

  http://sourceforge.net/projects/shelled/files/shelled/update/

Happy happy~~
