I'm having some conceptual difficulties understanding how Eclipse works.
I've got a project for an Android application, which I created using the ADT wizard. Things I see in the Projects panel in Eclipse more or less resemble the contents of the filesystem directory which was generated in ~/workspaces/MyProjectName, so I suppose that what I see in Eclipse is more or less a reflection of the filesystem.
Now I want to add some subproject/library which I checked out from github (as a git submodule) into a sub-directory inside ~/workspaces/MyProjectName. I also edited classpath.xml to point to the new location, hoping that Eclipse will read the file, see the new location and everything will work.
However, this didn't happen, the directory never appeared in Eclipse and Eclipse tried to pretend that it doesn't exist at all (i.e. not allowing me to build the project which referenced the code from the new directory etc.)
I tried to add the directory to the folder manually inside the project, but Eclipse complained that the directory already exists in the filesystem so it created nothing.
Obviously I'm doing something wrong :)
The questions are:
Am I supposed to do everything via Eclipse, including file operations, working with VCS etc.? I'm fairly proficient with terminal and would not want to have to figure out how to do everything via a point-and-click interface.
Is there a sane way to make Eclipse to re-read the project structure from the disk?
Where does Eclipse store its settings for each project? I was hoping to be able to make the project self-contained, so I can check it out on any machine and be able to work without having to manually re-configure stuff in Eclipse, but that would not work if Eclipse stores its configuration for the project somewhere outside the project's directory.
