I recently created a workspace and imported a number of projects into it. One of the projects, which is present in the classpath of several other projects, has been imported in the closed state (leading to build path errors). How do I open that project in the workspace to resolve build path errors?
Edit: The project is not visible in the workspace although I have seen it in the workspace folder.
The solution that eventually worked for me was switching to Navigator view, where I could see the closed folders which were not showing up in the Package Explorer or Project Explorer views. I just opened the closed and (previously hidden) projects from the Navigator view and the projects were visible in the other views as well. (Just to clarify, the reason I was unable to open the closed project was Filters, explained in the edit.)
EDIT
In the drop down menu at the top of the Package Explorer view, the Filters option is set to hide closed projects. Allowing closed projects to be visible in the Package Explorer will resolve the issue I was facing.
