problems installing MPS plugin in OS X Tiger

Hi

Anybody using MPS on OS X Tiger?

When I try to install the MPS plugin I get a message 'Plugin isn't installed. Shut down IntelliJ IDEA and try again'

By the way, in case it is related to the problem, after I start mps using mps.sh, I see the log entry

  ERROR - s.reloading.ClassLoaderManager - Can't find rt.jar. Make sure you are using JDK 5.0

in my console, even though my default JVM is jdk5.

What directory did you choose for plugin? We had problem before when you

can't choose IDEA directory in chooser dialog. In this case you can

extract contents of archive in %MPS_HOME%/plugin to

%IDEA_HOME/plugins/MPSPlugin

By the way, in case it is related to the problem, after I start mps

using mps.sh, I see the log entry

  ERROR - s.reloading.ClassLoaderManager - Can't find

rt.jar. Make sure you are using JDK 5.0

in my console, even though my default JVM is jdk5.

If you run MPS on JDK other than JDK5.0 it will fail so i think problem

isn't in JDK. I think structure of jars on MacOS is different than on

Windows. We need rt.jar because most used java classes are placed in it

and without it you couldn't write the simplest language tutorial which

requires such classes as System, String. As a workaround for this

problem you can add jar in project paths (Icon with tool -> Project Paths).
