[news.eclipse.tools] Re: how to open a project with 2.0 and 2.1m5?

[chaves@xxxxxxxxxxxxxxxxxx (Rafael Chaves)]

JM, 

You cannot run 2.0.2 and 2.1 alternately on the same workspace (although
you can use 2.1 on a workspace created by 2.0.2, but then the workspace
will be upgraded to 2.1 and will not work anymore with 2.0.2).

If your projects are located outside the workspace (they don't have a
default location), you should be able to have a 2.0.2 workspace and a 2.1
workspace sharing the same project.

You can also share a project using CVS and work on it using 2.1 while
other users use 2.0.2.

But for these two cases, you can face some issues related to the
classpath and the .project files, which are kept in the project root
directory, and support additional features in 2.1 that won't work in 2.0.2.

There are two PRs regarding these issues:
