I am using Eclipse Mars.1 (4.5.1) with EGit 4.1.0.
After a merge from a branch into master, I cannot figure out how to tell EGit to resolve a conflict by simply keeping the version that was in master before the merge, ignoring anything that came into that file as a result of the merge.
This is what I do. My Java projects all point to master. No uncommitted changes in any project.
In Package Explorer view I right-click a project, click Team, Merge.
In the "Merge 'master'" dialog that pops up I select a branch (under "Local"), I leave the "Merge options" on "Commit" and the "Fast forward options" on "If a fast-forward, only update the branch pointer".
I click "Merge". The "Merge Result" dialog pops up and says "Result Conflicting". Fair enough, I was expecting conflicts and I'm going to resolve them manually one by one.
Now, my problem is that for some of the files in conflict the way I want to resolve the conflict is simply to reject any change to that file resulting from the merge; just keep that file as it was before I did the merge.
This should be trivial to do (at least in SVN it was), but I cannot see anywhere in Eclipse how to do that. The merge has filled the file with the "<<<<<<" conflict markers and I just don't see what needs to be done to revert those changes only in that file so that that file simply becomes unchanged with respect to master, which is where all the projects are pointed.
If I right-click on the file in the Synchronize view and select "Overwrite", I am asked if I "want to overwrite local changes". That's exactly what I want, I want the file to have no local changes, so I click Yes. But the result is that the file gets deleted locally, although it exists both in master and in the branch. It disappears from Package Explorer, and since I also had it open in the editor, that editor tab closes away. That's not what I meant by "overwrite local changes" and I don't understand why it happens.
If instead of "Overwrite" I select "Mark as merged" (although the conflict markers are still there), the file is no longer shown as in conflict, but it still has all the conflict markers in it and of course is still shown as changed, while I want it to be unchanged with respect to master.
And if instead I resolve all the conflicts in the other files and I want to commit all the files except the problematic one - so that that one will stay unchanged - when the commit dialog shows up and lists all the files to be committed, each with a checkbox, and I click on the checkbox of the problematic file to exclude it from the commit, the checkbox doesn't get unchecked, and this goes for any of the other files; the checkboxes don't look disabled, but they don't respond to the click.
What am I missing ?
As of now checkout ours/theirs is available on conflicting files in the EGit staging view only
This problem got solved for me in the following way. I don't think it's the proper way (and I'm still interested in hearing about that if anyone knows) because it involves switching between two different Eclipse views, but at least this did the trick for me, and the only reason why this involves the "Synchronize" view is that nowhere else can I find the "Mark as merged" menu entry when I right-click on a file in conflict (neither in the "Git Staging" view nor in Package Explorer).
Open the "Git Staging" view. The files in conflict are shown under "Unstaged Changes".
Among them, right-click the one for which you just want to revert any change resulting from the merge in order to just keep the file unchanged. Then select "Replace With / Ours".
Go to the "Synchronize" view, right-click the file, Mark as Merged.
Now in Package Explorer the file should be shown as not in conflict, just unchanged, so it won't be included in a commit.

I'm using Eclipse 4.4RC4 with Subclipse 1.10.5. I added small chnages in r1000 that I don't need anymore, so I asked Eclipse to revert all changes in r1000. This mostly worked, except that FooBar.java has since moved from /path/old to /path/new, so I can't commit and I get the following "SVN Tree Conflicts":
/path/old/FooBar.java local missing, incoming edit upon merge
I have two questions:
Why didn't Subversion/Subclipse follow the move history and simply merge the changes in FooBar.java in its new location?
What's the correct way to resolve this? I suppose I could revert the changes to the non-existing FooBar.java file in the "SVN Tree Conflicts" tab, but that would do away with the merge metadata, wouldn't it? Wouldn't that mess up future automated merges, as Subversion would think that this particular change from r1000 hasn't been merged, yet?
I realize that similar questions have been asked before on this forum, but I found none specific to Eclipse/Subclipse, and none seemed to provide a good solution in that context.
It turns out that the Subclipse "SVN Tree Conflicts" tab (Team|Show Tree Conflict as others have noted) offers a Resolve... option in the main context menu of that tab (not in the Team context menu). Clicking on it brought up a resolve dialog that allowed me to choose the new destination of FooBar.jar so that the merge could continue and be applied to the correct file. Very cool! The merge succeeded, the correct destination file was modified, and I was allowed to perform the commit.
I'm using MercurialEclipse 2.1.0 (looks like latest) with Eclipse Indigo.
I can't seem to find a way to see the entire history of a file as available in remote 'central' repository (e.g. like it works with SVN) -- the history only seems to show up to the revision that I currently have in the workspace (in other words in e.g. Synchronize view (in workspace mode) I can see that there are 'incoming' changes in file but 'Show History' wouldn't show me anything about these changes).
Even if I 'Pull' (without 'Update') and check file history it still seems to stop at the current revision.
Anything I can do?
Is there any way
With MercurialEclipse the Synchronize view works best with the "Mercurial Changesets" model. Switching to that will show all of the incoming changesets (be sure the "All branches" button is pressed).
For the 2nd item, having pulled all the changesets, you can see all history if you press the up arrow button in the history view once. This will show all history for the folder that contains the file.
I am using Eclipse Indigo and subeclipse as the svn plugin for eclipse. Now here is the situation. I was synchronizing my project with the remote repository. There were conflicts present and I mistakenly clicked on "mark as merged" for one of the files without merging it. I tried restarting eclipse and some other stupid hacks. But nothing works out. So is there a way to undo "mark as merged" action?
Mark as Merged means that the local version of the file contains the content you want, after having compared the files and manually resolving issues. Subclipse still has to update the local file so that SVN's metadata is happy, so it saves the current content of the file, runs svn update, and then replaces the file.
So you can now run Team > Revert if you want the file to match what was in the repository, or Compare with > Base Revision if you just want to examine the differences again and possibly make more changes.
Neither of Marks suggestions worked for me. The class did revert back to the original (pre-merged) state, but trying to Merge again just gave me a 'no differences detected' message.
What did end up working for me was to Compare With > Local History. I was able to pick a version that was right before I hit Mark As Merged, and that got me back to the Compare Editor view that I had during the original Merge (which showed all the conflicts). I was then able to change the code correctly, and Mark As Merged again.
Delete the local project and re-import it, and this has the effect of undoing an accidental 'Mark as Merged' action. Just make sure that the deletion won't result in loss of uncommitted work.
Me and my friend using flex builder (eclipse based) with subclipse for a project.
Before committing I always update but sometimes I could not commit because of conflicts. Then I use Team->Synchronize with Repository and it shows at the right side latest from repository and at the left side the my current working copy. It has a button to copy from all non-conflicts from right to left (from latest repository to my working copy). But there are still conflicting lines.
Sometimes I just want to copy from left to right but there is no button for that (I mean overwriting repository file lines with my lines). After copying non-conflicting parts from right to left I just want to commit left side (I want to overwrite and commit my final file to repository). I cannot commit because of these conflict issues. Then my friend can use Replace With-> Latest from Repository command to get latest overwrited version.
Subclipse documentation is weak I could not find any good guide on the Internet. Could you explain subclipse conflict resolution step by step for a dummy like me? A video showing the steps, or an alien technology to fix it quickly will be fine. Are there any better (easier) solution for source control for eclipse?
(I use subclipse 1.4)
Yes, you are right. There is no button for that. in the Diff View(Side-by-Side View) the items in red are in conflict. They can not be automatically merged. You must review the item in conflict and manually resolve it by copying/editing the block of code that is in conflict.
After committing to or updating from repository(Synchronize with Repository) you'll see in the Console view that some items are in conflict. When you take a look at that file in Package you'll see 3 files right next to your original file:
myfile.txt (original file)
myfile.txt.mine
myfile.txt.r3293
myfile.txt.r3501
Right-click your original file then select Team -> Edit Conflict. In the Diff View provided, edit the file on the left-side to match the final result you want. (i.e. You may want to keep some of your changes and copy over new update from the revision in SVN, discard all changes and only keep your changes, etc.) After you are done, save the file. Right click your original file again then select Team -> Mark Resovled.
You will see that the addition 3 files disappear. You can now "safely" commit your work.
There is no easy way to do this since SVN can't decide what's the best option when such conflict arise.
I know this thread is old, but if someone is looking for an updated answer, my experience can help.
I'm using subclipse 1.8. Right-clicking on the original file and selecting "Mark Resolved...", you'll have several options, among others, take the local file or the base file as the correct version. You can save time with these options.
I can't find "Mark Resolved" so instead I clicked "Mark as Merged" after manually deleting the generated files.
Do the following steps:
Copy your latest working updates to a safe place.
Select the file which has conflicts..right click > select replace with>>Select Latest from Repository.
Then go back to your saved working copy and manually replace the current file contents (which has been overwritten in above step) with yours.
Then from team select Commit...
This way conflicts should be resolved and you saved your latest updates to SVN Repository.
I'm pretty used to how to do CVS merges in Eclipse, and I'm otherwise happy with the way that both Subclipse and Subversive work with the SVN repository, but I'm not quite sure how to do merges properly.
When I do a merge, it seems to want to stick the merged files in a seperate directory in my project rather than overwriting the old files that are to be replaced in the merge, as I am used to in CVS.
The question is not particular to either Subclipse or Subversive.
Thanks for the help!
Merging an entire branch into trunk
Inspect the Branch project history to determine the version from which the branch was taken
by default Eclipse Team "History" only shows the past 25 revisions so you will have to click the button in that view labeled "Show All"
when you say "Show All" it will take you back past the branch date and show you all the history for trunk as well so you'll have to search for your comment where you branched
NOTE: if you use Tortise SVN for this same task (navigate to the branch and select "Show Log") it will show you only the branch history so you can tell exactly where the branch began
So now I know that 82517 was the first version ID of the branch history. So all versions of the branch past 82517 have changes that I want to merge into trunk
Now go to the "trunk" project in your Eclipse workspace and select "right click - Team - Merge"
The default view is the 1 url merge
select the URL of the branch from which you are merging
under Revisions select "All"
press OK
This will take you to the "Team Synchronizing" perspective (if it doesn't you should go there yourself) in order to resolve conflicts (see below)
Re-Merging more branch changes into trunk
Insepct the trunk project history to determine the last time you merged into trunk (you should have commented this)
for the sake of argument let's say this version was 82517
So now I know that any version greater than 82517 in the branch needs to be merged into trunk
Now go to the "trunk" project in your Eclipse workspace and select "right click - Team - Merge"
The default view is the 1 url merge
select the URL of the branch from which you are merging
under Revisions select "Revisions" radio button and click "Browse"
this will open up a list of the latest 25 branch revisions
select all the revisions with a number greater than 82517
press OK (you should see the revision list in the input field beside the radio button)
press OK
This will take you to the "Team Synchronizing" perspective (if it doesn't you should go there yourself) in order to resolve conflicts (see below)
Resolving Conflicts
You should be at the "Team Synchronizing" perspective. This will look like any regular synchronization for commit purposes where you see files that are new and files that have conflicts.
For every file where you see a conflict choose "right click - Edit Conflicts" (do not double click the file, it will bring up the commit diff version tool, this is VERY different)
if you see stuff like "<<<<<<< .working" or ">>>>>>> .merge-right.r84513" then you are in the wrong editing mode
once you have resolved all the conflicts in that file, tell the file to "mark as merged"
once all the files are free of conflicts you can then synchronize your Eclipse project and commit the files to SVN
I typically check out both branches and then use the compare to each other option which does a synchronize-like compare of the two source trees. After integrating the changes into one branch, you can recommit back to the repository.
Use Eclipse integration, it works perfectly fine.
The main change from CVS, is that you only merge deltas from a branch, ie changes from one revision to another.
That is to say you have to track the correct start revision somehow (unless you have svn 1.5 merge history)
If you got that right, it's only up to you to get the changes right with the compare editor.
Firstly, if you are seeing ">>>>>" and such in your files when you view them in Eclipse, this probably means that you are not looking at the file with the proper compare editor. Try right-clicking on the file in the Project view or Synchronize view and selecting "Edit Conflicts" to bring up a compare editor that will show you the conflicting regions graphically rather than as text. Note that the compare editor that comes up for "Edit Conflicts" is different from the one that you get when you just doubleclick on a file in the Synchronize view -- the doublieclick compare editor shows the differences between your current file and the way it existed when you last checked it out or updated it, while the Edit Conflicts compare dialog shows the differences between two sources of changes (for instance, the changes you merged versus the changes that existed in your workspace before you merged).
Secondly, you may wish to be aware of a bug in some versions of the Eclipse subversive plugin which causes all files that accepted merge changes to be incorrectly marked as having conflicts. This bug has been fixed, but a lot of people don't seem to have updated to get the fix yet. Further details here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=312585
Remember that with svn reverting a modified tree to a clean state is fairly easy. Simply have a clean workspace on the merge destination branch and run the merge command to import the modifications from the merge source branch, then synchronize your workspace and you will get your usual eclipse comparison window showing all the merge modified files and the conflicts.
If for some reason you can't solve the conflicts you can svn revert on the project and go back to a clean state, otherwise you do the merge in place and once you are done you can commit. Note that you don't have to commit, once you are done handling the conflicts you can also return to the dev view, verify that the code compiles, run your unit tests, whatever and then synchronize again and commit (once the conflict are locally resolved they won't come back)
last time I looked, when you use subclipse merge command it will overwrite the merged file (using conflict markers to show conflicting areas) and put the original left and right side of the merge in the same place. it shouldn't put anything in different directories.
As a rule of thumb, it is best to commit all merge modifications in a single commit and to only have the merge modifications in the commit so that you can rollback the merge later if needed.
openCollabNet's merge tool for subclipse is pretty neat. There are many merging types available and the merging I just performed with it when seamlessly. I recommend it.
The one thing that syncrhonize view in eclipse lacks is check-in capability. In Team synchronization view I can view all my changes and resolve conflicts, so it would be rather intuitive to check-in right there instead of going back to java view and do check-in.
I would advise not trying to use Eclipse's plugins as your primary access to Subversion.
If you are developing on Windows, TortoiseSVN is the best program that I have seen for Subversion access. Explore to the directory of which you wish to merge, right click on it and use the Tortoise SVN merge option. Assuming a non-interactive merge, once you get conflicts, you'll have to go through each conflicted file and edit the conflicts before marking them as resolved. For this process I recommend a program called KDiff3, which shows your local repository copy (what was stored in the .svn before the merge), your local copy (including any changes), and the copy coming from the repository, and allows you to easily see (and even hand-modify if needed) the result of the merging. It also handles a bunch of minor conflicts automatically.
KDiff3 is portable, TortoiseSVN is a windows shell extension, so if you're using another environment, I would try to just use SVN to merge. But that would be much more of a pain :)
I landed here because I was looking for a way to merge in an external merge editor (KDIFF3) but start the merge from eclipse. I wasn't satisfied with the answers provided above. So here is ho to configure kdiff3 as merge and diff editor for SVN in eclipse:
go to Windows -> Preferences → Team -> SVN -> Diff Viewer
Add a new config (add button):
Extension or mimetype: * - if you wish you can specify different mimetypes for different editors, I didn't need that thus the alquantor.
Diff:
Program path C:\Program Files\KDiff3\kdiff3.exe (or wherever you have your merge editor - sry for the windows path, feel free to add a linux version in the comments or edit this answer.)
Arguments:
${base} ${mine} ${theirs}
Merge:
Program path C:\Program Files\KDiff3\kdiff3.exe
Arguments:
${base} ${mine} ${theirs} -o ${merged}
This will probably work as well for other merge editors, but with a different argument syntax (figure it out an let us know :) ).
The usage is as usual (team->edit conflicts) for merging and compare->foo for the diff view.
Cheers
