I'm trying to install liferay IDE (from tutorial: http://www.liferay.com/documentation/liferay-portal/6.0/development/-/ai/installation)
The problem appears after I checked the Liferay IDE checkbox and press Next. Error popup appears telling me this: "org/sat4j/minisat/core/AssertingClauseGenerator java.lang.NoClassDefFoundError".
What is the problem?

That class is used by the Eclipse p2 framework which has to do with installing new plugins. It appears something is malformed in your eclipse installation for the Update manager to not be able to find that sat4j class. The requirements for Liferay IDE are to use the Eclipse IDE for Java EE Developers, which can be found on this page: Eclipse Downloads Its the top link.
If you are using that package and still see the error try restarting eclipse and give it the -clean commandline flag in eclipse.ini which might clear the NoClassDefFoundError.
A final option would be to down an eclipse that has Liferay IDE pre-installed, which you can find at this page: Liferay IDE Downloads Page

Hi, I already using Eclipse IDE for Java EE Developers, so that is not the case. I've put "-clean" command in eclipse.ini file, restarted IDE, the same problem. – Almas Adilbek Jul 20 '11 at 05:24

Do you have the sat4j bundles in your plugins folder? org.sat4j.core_2.3.0.v20110329.jar, org.sat4j.pb_2.3.0.v20110329.jar, org.slf4j.api_1.6.1.v20100831-0715.jar – gamerson Jul 20 '11 at 20:24

It sounds like something is corrupt with your installation. You could try one of the pre-packaged bundles on the liferay-ide downloads page (use the combobox dropdown) and give that a try as a fall-back. – gamerson Jul 20 '11 at 20:46

You can install Liferay IDE via eclipse marketplace. (Help -> Eclipse Marketplace)

Could be your Eclipse install is somehow weird .. Maybe you get a fresh copy of Helios and try it again ... – koeckc Jul 25 '11 at 11:39
