I read few threads on backing out commits. Following are relevant
How to delete commits with egit?
What's the difference between Git Revert, Checkout and Reset?
But how do I revert/reset/restore back to clean original state. I just started working on new project and the original git directory structure got messed up after the first check in (because I incorrectly created git repository as eclipse project); this problem is discussed in "The short story" or "The longer story" of following link
http://wiki.eclipse.org/EGit/User_Guide#Creating_Repositories
Now I wanted to restore the original directory structure of git repo. In History window, I see all the previous commits and I can right click on them and back out to one of previous commits; sadly the history window doesnt show anything to prior first check in (or commit). But I want to back out to the original directory structure that existed prior to first commit (that way I will have clean repo without any code base in it). It doesnt matter if it is restore/reset/revert as long as git repo looks same as it was before first committ. Can I do this in eclipse/egit?
This isn't something that Git would have kept track of.
You might look into the Eclipse local history (which is separate from the history recorded by Git), but that is for a file only. Not a all structure.
It is best to recreate a Git repo, and make as a first commit your clean structure, before adding code base in it.
Go to git perspecive-> Expand the repo. Right click on working tree. Clean. Finish. See the below pasted image link.

We recently moved to git from svn (both using Eclipse). I am in the (perhaps bad) habit of writing my Java code first, getting everything to work and then going back and adding comments. In SVN this was easy. I would just create a Fisheye review with my Jira task. The review would have a list of all the files I changed and methods I added or modified. I would note it and abandon the review. Then I would edit all the files listed and add the comments.
However, Fisheye does not (I believe) work with git. I could do a git status to see the files I changed but the local branch is already updated so it will not list any files. And all it does is tell me I am something like one commit ahead of the remote branch but does not list any files.
Is there some way to see a lit of the files I have changed with git so I can add comments? And when I say I wait for my comments I really mean mostly for added classes and methods. If I do something like add a line or two to a method I will generally add the comment too.
changing comments on git commits is not that easy. Each git commit has a sha-checksum which also includes the previous git commit. If you change a commit you change the current commits sha-checksum. therefore you create a new commit. All following commits of your branch must now be rebased on top of this new commit.
The command line provides the git rebase -i [commitid] where you can do lots of modifications including changing comments on commits. I never did this with a GUI but egit might support that too. Just refer documentation on egits rebase feature.
I found out how to do this.
The "Synchronize Workspace" in eclipse appears to show all the changed files not yet pushed remotely. I have not done any pushes, so this showed me what files changed.
I'm transitioning from using Subversion in Eclipse for code management to GitHub in RStudio. It's starting to make sense, but I can't seem to figure out how to pull effectively.
Specifically, if I use the Pull arrow in RStudio, every file change in the repository automatically updates my local files without warning. I can see how many files were updated, but not what changed!
Here are the questions I'm hoping to get help with:
1) Can I preview the repository file changes in RStudio before I pull them locally? With SVN in Eclipse, there was an indicator showing files with a difference, and the option to view side by side.
2) If multiple files have been changed on the repository, is it possible to pull just 1 locally?
3) How can I revert a local file to a previous version?
Right now I've been trying to do this all within RStudio for simplicity. I haven't used things like the GitHub desktop client.
I appreciate the help!
I would suggest you better get used to the git's own tools to stay informed about your repository.
For example you could do following.
Before you pull, check your current commit logs
git log
This should show you how your current commits stack up. Note the latest commit id (first 4-5 letters would usually do)
Now after pulling you can see the difference using following command
git diff --color your_previous_commit_id..HEAD
If you don't like the changes and want to go back,
you can just reset to your favorite commit with following command. BTW run "git stash save" to keep a copy of your uncommitted changes.
git reset --hard you_favorite_commit_id
Note: that this will delete all your uncommitted changes unless you stashed them and put your local branch behind the remote repo branch you are tracking again.
Wondering where to put these commands? Check https://git-scm.com/downloads.
What's good about using these git tools is that if you switch between IDEs you don't need to search for same functionalities you had in your earlier IDEs.
I have this strange behaviour from git, and even if i'll describe it from eclipse egit plugin, from terminal i have the same issue.
I have a project in the workspace that is shared between me and other developers, when i sync the project it says to me that i have to push something like 14/16 commit ant i have to pull one, even if had no commit at all.
Every time that i do the pull it seems that the project is now synchronized, so i push "team syncronize" again and the 14/16 commit to pull appears again.
That's not the only strange thing, another one is that i can push commit to remote after i have pull those commits but the other developers couldn't, even if they do the same things that i've done, it says to them that the problem are a "dangling blob".
Before write some of the solutions that i have found and what i have try i want to say that the number of commits are practically the entire history of the project.
I have tried to use the manual gc of git in the remote repository after i have done an fsck, where i have met effectively two dangling commit (why two dangling commit and egit says one dangling blob? i don't know....), this have removed the two dangling commit, so i have deleted the project from my workspace clone it again, but the same error happens again.
So i have used this other solution http://www.tekkie.ro/news/howto-remove-all-dangling-commits-from-your-git-repository/, always on the remote repository but the problem is still the same.
So even if have read practically all the documentation i didn't undestand somethings:
1) what's the difference between dangling commit and dangling blob?
2) how a dangling commit/blob happens?
3) how can i restore the project's repository?
UPDATE
I start a bounty because i really want to undertand and solve the problem, so for that i'll be clear in what i need to understand:
I have a project that everytime i use team syncronized, want to re-pull all the history, not only to me but for every one ofe my colleague, we use gitblit as remote repos. What can i do? Where do i have to search the possible errors?
UPDATE
that's EGIT
and that's the Terminal
This is only a answer to some of your issues, maybe it should a comment instead.
Commits and blobs (blobs contains file content) are all objects in the git DAG and an object becomes 'dangling' (unreachable, orphan or loose) when nothing reference it (i.e. not part of the history) and git will clean up dangling objects if you run git gc (removes dangling objects older than 2 weeks) and some git commands will also run git gc --auto when they are done with their operations.
When you make changes in the DAG (i.e. rebase, amend or re-add content to the index) some objects will be replaced with new ones and the old objects then becomes dangling.
You can run git fsck --unreachable to find objects that are dangling.
Note: Objects referenced by reflog are normally not considered dangling.
In your case you may need to run git prune, git gc --agressive or git gc --prune=now to remove all dangling objects (do not forget to make a bakup first, just in case)
I'm running Eclipse Kepler Service Release 1 with egit for versioning. I've been using eclipse and egit for just a few months and am not up on all of it's intricacies yet. I've found some related questions here for git, but I don't really understand how to use egit to accomplish what the answers propose.
The immediate problem I have is that no files are visible in the project tree except for the libraries and WEB-INF under war. The files show up in the unstaged changes area of the Git staging window marked with an x as deleted. This is a jsp project running google app engine if it matters.
What got me to this point was attempting to checkout the master branch. I got an error saying the branch could not find 2 files and afterwards my working files in the current branch disappeared. The Git repositories view shows my current branch is the same as the one I had been working on, so these files should normally be visible.
Since I never chose to delete these files I have no idea what stage egit thinks it's in. I don't have a backup and my other branches haven't had recent changes merged in.
You can always see the state of Git as a text decoration next to each repository node in the repositories view of the Git perspective. Normally that should only show the branch name, but it might also be something like "Interactive rebase", if Git stops for user input in the middle of an operation.
If that is not showing the branch name you want, then just the context menu Switch->[branchname] should bring you back to the wanted branch.
If everything else fails, you can always throw away all local changes and have your local working directory reset to the state of any commit (or branch) by using context menu->Reset->Hard and select the commit (or branch) to which you want to reset. Be aware that this wipes out any uncommitted local changes.
In case of more questions, you should read the very detailed EGit user guide.
I'm working on a project in Eclipse that was cloned from a GIT remote repository. The Eclipse eGit plug-in allows you to get going without really understanding anything about GIT, which is where I was. I've eventually realized that when I do a "compare with HEAD revision" I'm not as I first thought comparing with the remote repository, but with my local repository. I understand now that I need to pull updates from the remote repository, but it's not clear what will happen to my local changes. I've not committed these changes, partly because I thought I might be updating the remote repository (I realize now that I won't) but partly because I find the Package Explorer file decoration (">") is useful in identifying the files I've modified. If I commit then I assume these indications will disappear.
My questions:
How do I update my local repository without losing my changes?
Can I do this without losing my modified file indicators?
Update: I thought I understood how some of this worked, but I'm really lost now, particularly by the relationship between workspace and (local) repository.
I used Team->Pull to update my repository. Since I've not committed any changes, I expected this to work without conflict, but it flagged up all the changes between the workspace and repo as conflicts (confusion #1).
I assumed I needed to use Team->Synchronize to bring changes into the workspace, as I would with other VCSs. When I do, I see the changes, but not even the non-conflict updates have been applied to the workspace and there is no "Update" operation to do this, so I don't know how to apply them (confusion #2).
For the conflicting updates, I manually merged the changes into the workspace copy and used "Mark as merged", but this seems to do nothing. The conflict is not cleared. I would expect at this point the change would just be an uncommitted change in the workspace (confusion #3).
I read elsewhere that to remove conflicts I should use Team->Add and Team->Commit, but I don't want to commit my changes as I explained originally (confusion #4).
You can see I'm confused! Any help will be much appreciated.
If git pull does not work, you can use this:
git stash
git pull
git stash apply
not sure eclipse supports stash, so you may have to use the command line.
