How do I install TortoiseHG/Mercurial Plugin in Eclipse?

Question

Yesterday i downloaded new eclipse indigo. I had problem with java (no wirtual machine....), so i added new patch to java location. However i instaled mercurial plugin from http://mercurialeclipse.eclipselabs.org.codespot.com/hg.wiki/update_site/stable and it doesnt work so well, and afterward when I open Eclipse its says "Problem Occured" and shows:

checking encoding (cp1250)... checking Python lib (E:\Programy\TortoiseHg\library.zip)...
checking installed modules (E:\Programy\TortoiseHg\library.zip\mercurial)...
checking templates (E:\Programy\TortoiseHg\templates)...
checking commit editor... Can't find editor 'notepad' in PATH (specify a commit editor in your configuration file)
checking username... no username found, using 'lolek@lolownia' instead
1 problems detected, please check your install!.
Command line: hg -y debuginstall"

Answer 1

Your answer is right in that output. It's saying you have to problems, one fatal and one not:

checking commit editor... Can't find editor 'notepad' in PATH (specify a commit editor in your configuration file) checking username...

When you do a commit Mercurial needs to launch a text editor. By default on windows it launches notepad but the check isn't finding notepad in your path. Find where youre notepad.exe is and make sure it's on your system path. Here's the first google hit for that; I haven't done it in 15 years: http://www.computerhope.com/issues/ch000549.htm

no username found, using 'lolek@lolownia' instead

You've not set a username for your commits, so they'll all show up as lolek@lolownia if that's a string you're happy with sharing with the world you're great, otherwise follow these instructions:
