Can Galileo work with workspaces/projects created in Helios?

My desktop has Helios (3.6.1). My workspace and the projects under it were created using Helios.

My laptop has Galileo (3.5.2). I tried to open a copy of a project that was created through Helios and it opened fine.

But then, when I tried to change one of the Java Libraries via Configure Build Path, I received Access Denied error:

Can Galileo work with workspaces/projects created in Helios?

At first, I thought it w开发者_StackOverflow社区as a Windows XP permissions problem, but after investigating this further, I ruled out this possibility. I have also been able to modify that .classpath file using Notepad, so clearly this isn't an ACL problem.

Therefore, I am now suspecting that there is an incompatibility problem between Galileo (3.5.2) and Helios (3.6.1).

Can you confirm this?

If there shouldn't be a compatibility issue between the two, what could I possibly doing wrong?


The solution at this post - http://blog.ryanrampersad.com/2010/03/03/setting-build-path-has-encountered-a-problem-in-eclipse - may help you!

Summary:

"The windows hidden attribute is set on the .classpath file. Removing this attribute fixes the error. After going into the workspace and project directory, remove the hidden attribute."


Unfortunately, I celebrated too early. While Saket's tip allowed getting rid of the build path error, numerous other problems emerged, which forced me to upgrade from 3.5.6 to 3.6.2.

I then discovered the following in Eclipse's Release Notes:

Note: Copying your workspace is recommended because, after you've upgraded your workspace, you won't be able to use it again with an older version of Eclipse. If you ever want to go "back in time" to an earlier release, you will need that backup.

Therefore, the short answer to my question is simply: No!
