How to pull changes for multiple projects at once - eclipse

I'm using Eclipse with the MercurialEclipse extension to use the Mercurial SCM.
I have lots of projects and every morning I want to pull all latest changes before starting to work. With SVN or CVS I could simply select all projects and click Team/Update. But the Team/Pull command of MercurialEclipse is disabled when multiple projects are selected.
So currently I have to call Team/Pull on each project separately. That's really annoying. How can I pull changes for multiple projects in one go?

I would rather use an external script than trying to do it directly from Eclipse.
See for instance:
Mercurial Repository Nightly Pull from a subdirectory on a server (for the idea)
Updated Mercurial Batch Pull/Update Python Script (for an actual complete script)
Then a simple refresh in your Eclipse environment would be enough.

You could highlight them all, right click, and choose synchronize. You could then pull from this view if desired (plus it will show you changes).

One not-quite-what-was-intended solution would be to make each a subrepo of of parent repository. Something with a .hgsub file of:
project1 = project1
project2 = project2
...
would be enough for 'hg pull' in the top level to do a pull in all of them.
You're probably better off just scripting it though. I don't know what eclipse offers for scripting but from the unix command line that would be:
for therepo in $(find /my/project/root -type -d -name .hg) ; do
hg --repository ${therepo%.hg} pull
done

Eclipse Projects And Git

I used computer A via the Terminal to create a) create a git repository, b) add an index.html file to the repo, c) add a remote origin, d) push to the remote origin. All OK.
Then, i used computer B to clone that repository via Terminal. Then, I opened Eclipse (equipped with Egit), and created a new project in the folder that was created by the cloning process. Then I used Eclipse to push any changes to the remote origin.
Returning to computer A, I used Eclipse to create a project in the original repo folder, and then I attempted to pull from the remote origin, in order to get the changes that were pushed when using computer B.
Eclipse will not do it. It complains the I have items such as .settings, .project and similar and since they are not under version control it won't overwrite them by fetching files from the server. I had to manually delete those files (via Terminal) and then Eclipse worked as expected.
Please provide information on how to avoid this.
Should I create the local repo from within Eclipse and then push it to the remote origin, so that items such as (.settings) are under version control and (if so) how would that cause trouble to people cloning the repo and use different versions of Eclipse?
Should I gitignore those items?
Should I ask Eclipse to save its own affiliated files to another folder (not that i am aware how to do that, i only know that NetBeans does it)?
Looks like you didn't gitignored eclipse files.
Probably, when you commit/push via egit, you also commit and push those files you already had unversioned in your machine A, so git complains, because you are asking to override existing unversioned files.
I strongly recommend you to gitignore those eclipse files. You can see examples of .gitignore files in the github gitignore repo.
Hope it helps.
It complains because if you pull the changes from your remote it will overwrite your local files. That is the problem. The other answerer has right. You should better add all the eclipse project files and and target .settings and classpath to gitignore. You can use a global gitignore for your computers as well, before creating projects. You could use maven for example, then you can import your projects only from the pom.xml-s given in the git repository.
I use them the same. Egit and other guis are a bit too complex to work with. Git repositories can get easy in an inconsistent state where you should use the oldfashioned terminal to solve things. Like, rebasing, merging on conflicts. Gits learning curve is solid.
Now you can solve your problem if on the first computer save a backup of your original and clones your project later, after fixed it on the second. On the second git remove all this files, but use the --cached option to avoid deleting them. Before you do it so, check the help of git remove! after you have done this, put them into the .gitignore as filenames with wildcards. You can also use a global gitignore file in your user folder. Creating a .gitconfig file where you can specifiy the global ignore with the following :
[core]
excludesfile = ~/.gitignore_global
Than just create the .gitignore_global like this :
/nbproject
/bin
/build.xml
.idea
chess.iml
target/
bin
( This file is for idea and netbeans. you can add eclipse project files here )
You can have .gitignore files per project too. You can commit them to the repository, so on the next machine you do not have to do this again. The nicest way I think is having a dotfiles git repository, which is a git repo of your home directory and the dotfiles in it. I also use it for different windows and linux distros.
That's all. You should keep all of your configuration in a safe place. And source code management can do it. But do not commit private stuff to public a place! ;)
Oh I wanted to mention that, you can also have a .gitignore entry in your .gitignore file. That can be very useful when you do not want to touch a repository but need to add a gitignore to hide some stuff especially from the given repo.

Use CVS and GIT together in Eclipse

I already have a CVS and that cvs is used to share the source among other developers. But I need to keep a track of my source code changes separately. Moving the project from cvs to git is not practicable here.. and you may think that why 2 versioning controls. Any way I need to have a separate repository. I have tried git with eclipse. It is ok. I want to know how I can use both my personal git repository and cvs together in eclipse. (For example, when I commit my changes in eclipse, Team -> commit .. How can I separately commit to both cvs and git..and whenever I need to see the history in eclipse, separately git and cvs.. .Also when CVS server is not supporting, I can work with my local git repo as well. ) I need to handle all in eclipse IDE. Any one give any tutorial or links for my solution, it is highly appreciated.
You can have a git repo directly within your sources, but Eclipse would still be set on using CVS (and cannot show you both git and cvs commands at the same time).
That means you go on committing with CVS and Eclipse, but would need to commit (locally) in Git with an external tool (either a simple command-line session, or any GUI you want, like GitHub for Windows or SourceTree)
It actually is possible, if you create a dummy Eclipse project and designate the git repository at the workspace root (.git directory at same level as all projects in the workspace). This way when you make commits from this project, all projects in the workspace are its members and you can keep the members themselves connected to cvs.
You can create such repository by first creating the dummy project, and (Team->Share) sharing it via git using the Configure Git Repository dialog. Select “Use or create repository in parent folder” and explicitly remove the project folder from the "Create Repository" line after checking (checkbox) the project from the list of available projects.
After pressing "Create Repository" the project directory suffix will reappear, but remove it again before pressing Finish. In my version of Eclipse pressing Finish will hang, and I must terminate Eclipse to restart it.
After restarting the dummy project can be used to Commit files in all the other projects while the other projects remain connected to cvs.

Subclipse SVN first commit ignore certain directories

Decided to take the jump from CVS to SVN.
I setup a new repository in subclipse for my project. When I go to 'Finish' the setup it wants to do an initial commit and presents me with a flat list of files to select the files for version controlling.
The problem is I have thousands of generated binary files I dont want to commit.
So I click on cancel because it would take me all day to go through and unselect all the unwanted files. Annoyingly when I click on a parent category for the files I want to ignore it is not recursive!
So I click cancel then go to the eclipse directory structure for the project and manually set svn:ignore on all directories I want to ignore. Then I try and do a commit again and all the files are once again presented - ignore seems to have done nothing.
Can anybody point out what I might be doing wrong?
For the first commit, I recommend writing a small script to delete (of course you'll have a backup) all the files that are not meant to be committed.
Afterwards, if you find you accidentally committed a file, you can
svn delete file
Upon the first checkout, copy back (or better yet, regenerate) all the binary files. This will trigger svn to notice that your local repository is out-of-sync with the remote repository.
cd <Root of local repository>
svn status
You will see lots of "to be added" items. Go to the parent directory and add in svn:ignore properties for each of the generated items.
cd build
svn propedit svn:ignore .
which will open an editor (if it doesn't, you need to set the environmental variable SVN_EDITOR to a suitable editor). Then you can add in entries that svn will know are not tracked.
(in the ignore property editor)
target
build
image*
*.o
(and so on)
Save the file, and it will be staged for the next commit. Subsequent runs of svn status will no longer show these files as "needing to be added", but they will show the directory as "needing to be committed (it's a revision on the directory)"
Quick Aside
So I'm not entirely certain exactly which functionality of Subclipse you were using in order to create a repo and share a project to it, I'm assuming you created like a file based repo through the eclipse SVN repo view and tried to share and then commit to it. It looks like your problem got solved but I did want to add an answer on here because I ran across this post looking for the answer to this same problem of handling initial commits even just in general with SVN and wanted to offer help to anyone else looking for the help.
Intro
To start off I would recommend not working through an IDE extension like this just for the initial commit as they can miss a lot of the options for handling opening a repo in SVN. I personally really like the command line form of SVN to work with but TortoiseSVN is a good option for a GUI.
Whether you create a local file-based repo or are connecting to an SVN server and you want better control over your first commit in an previously unversioned project here is what I've found as the best general workflow for doing so.
Create the remote folder to save to.
On command line this will be:
$> svn mkdir your-url-scheme://your-site-address.domain/path/to/repo/example-directory
Or on TortoiseSVN open your repo for browsing, right click, and select "create new folder"
This will give you a location in the SVN repo to checkout from for our next step.
Checkout in to the already started project
Make sure to use the empty, newly created folder in your repo to checkout with. SVN does not actually require a folder being checked out to to be empty, which is an important part of what makes it actually very flexible and able to subsume parts of your directory into it fairly easily if used correctly.
Now you will checkout this empty folder into the root folder of your already started project. This will add your project to the working copy of this folder without any commit being made yet. The command is:
$> svn co your-url-scheme://your-site-address.domain/path/to/repo/example-directory /your/projects/root/
"co" standing for checkout. In Tortoise svn you can right click on or in the empty repo folder and select "checkout..." and then select the project root.
Set ignores and commit
Finally, you can easily set your ignores on certain files before adding any other files to the tree using the command:
$> svn propset svn:ignore file-or-directory-to-ignore
And to add all non-ignored directories and files:
$> svn add * --force
The force is technically unnecessary in this case but ensures full recursion. You can also now do all of this in your file explorer if using TortoiseSVN or you can even use your IDE extensions to do this at this point(make sure to ignore all files you need to before mass-adding files for commit), all that's left is to make sure to commit the newly added files to the repo and you're up and running with source control :)
Added this method here simply because this method allows you to avoid any unnecessary copying of those stinky binaries that no one wants to lug around with them.

Git, SVN and Eclipse workflow

I am trying to adopt the following workflow:
git svn clone a svn repository through command line (egit doesn't support git-svn)
Open the project in eclipse with egit since I rather use egit to branch, merge, commit etc...
When i'm ready commit the changes back, I use use git svn dcommit to commit back to svn
I am having trouble with step number 2, don't understand how to import a git project, eclipse tells me i can't import it to use the same directory it's currently in because another project with the same name is already there. this is confusing.
Anyone knows how to do this ?
Also would like to hear other workflow examples that uses egit and git svn. I am aware that it is better to do it all through command line, however, I am trying to ease the move to git for fellow developers in my team, who are not used to command line interface etc...
I've worked briefly with the egit plugin (I actually recently stopped using it and just use msysgit as my Git guiclient and run it separately from Eclipse). I find Eclipse very busy as is and adding this plugin slows it down (for me at least).
What I did when setting up an already cloned project in Eclipse:
In Eclipse. File -> Import -> Existing Project into Workspace
Select root directory of project. Do NOT check copy projects into workspace. Click finish.
After project has been imported. Right click on project, go to Team -> Share Project
Select Git as a repo type, click next
Check use or create repo in parent folder of project. Since you already cloned the project it will be tracked with git. When you check this option it will show the project, the path, and the repo (.git).
Click finish and you will be all set.
I think you'd better use SubGit instead of git-svn.
SubGit works on a server side. It synchronizes all the modification between Subversion and Git repositories automatically on every incoming modification from either side.
From the client perspective SubGit enabled repository is a usual Git repository, so you may pull from and push to it. Please refer to SubGit documentation or SubGit vs. git-svn comparison for more details.

EGit - Switching branches doesn't remove empty directories/packages

I'm using EGIT to manage my GIT repository, which seems to work well so far. However, when I switch from one branch to another the files are correctly switched, however empty directories and packages that exist in one branch but not the other are left over.
I understand that GIT is based on the actual files and not the directories, however this is not ideal as my one branch was a large refactoring and therefore contains many packages that the master branch does not have.
From my research there appears to be a GIT command git clean -d that should cleanup the directories. Does EGIT support this? Or is there a way to execute this command when switching the branch with EGIT?
That looks like bug 345585: "EGit does not prune empty folders when switching branches".
It is still opened, so for now, the git clean -d is your best option (but outside of Eclipse, in a shell session).
Update June 2013, for Egit 3.0 Kepler:
A clean action has been added to the repositories view now.
