C:\Users\Itu\workspace\Compiler>hg merge
abort: branch 'default' has 4 heads - please merge with an explicit rev
(run 'hg heads .' to see heads)
How you can see I have the one branch and 4 heads. When I try to pull in my eclipse mercurial plugin, it returns me message about multiple heads and offers me to rebase or merge. Then I did not understand anything and closed it. I think I need something to delete this heads. It would be great if somebody could explain me this and show how to do this in the eclipse plugin, but other help is appreciated.
回答1:
The safest way to remove the extra heads is to make a new clone, grabbing just the head you want with -r:
cd C:\Users\Itu\workspace
mv Compiler Compiler-backup
hg clone -r aa6af82c5458 Compiler-backup Compiler
This will move just aa6af82c5458 and its ancestors to the new clone, leaving the old heads in Compiler-backup. You can always hg pull them over later, or just delete the backup (losing your data).
回答2:
Mercurial has an entire wiki page devoted to the topic of multiple heads.
I highly suggest reading it before proceeding on your apparent course of action.
The folks at Fog Creek have provided some friendlier material.
You might consider working with them, since it sounds like you might need some support.
