Java – Eclipse: Some or all projects can not be imported because they already exist in the workspace

eclipsegitjava

I'm sorry, I know that question is asked quite often. But non of the scenarios suits my problem.

I'm using Eclipse (in Win7) with Git. Within a Git-branch I created a new project. Then I switched back on the master-branch. There the project is not in the workspace. But when I want to add it, I get the following error:

Some or all projects can not be imported because they already exist in
the workspace

My problem is, that the project is NOT in the workspace – as seen in Eclipse. But sure, it's on the hard disk, because it's part of my Git repository. So I can't delete it there. According to other posts, I removed it from this folder:

C:\Development\workspace.metadata.plugins\org.eclipse.core.resources.projects

But still I can't re-add it to the Eclipse workspace. Any idea?

This usually happens when you change the project directory physically without first delete in Eclipse. You can view and delete these hidden projects in the following view:

Window -> Show View -> Other -> Navigator

Then simply just continue with the process of import existing project.

Git – Do a “git export” (like “svn export”)

Probably the simplest way to achieve this is with git archive. If you really need just the expanded tree you can do something like this.

git archive master | tar -x -C /somewhere/else

Most of the time that I need to 'export' something from git, I want a compressed archive in any case so I do something like this.

git archive master | bzip2 >source-tree.tar.bz2

ZIP archive:

git archive --format zip --output /full/path/to/zipfile.zip master

git help archive for more details, it's quite flexible.

Be aware that even though the archive will not contain the .git directory, it will, however, contain other hidden git-specific files like .gitignore, .gitattributes, etc. If you don't want them in the archive, make sure you use the export-ignore attribute in a .gitattributes file and commit this before doing your archive.

Note: If you are interested in exporting the index, the command is

git checkout-index -a -f --prefix=/destination/path/

Git – Download a specific tag with Git

$ git clone

will give you the whole repository.

After the clone, you can list the tags with $ git tag -l and then checkout a specific tag:

$ git checkout tags/<tag_name>

Even better, checkout and create a branch (otherwise you will be on a branch named after the revision number of tag):

$ git checkout tags/<tag_name> -b <branch_name>
