Person you always been smack-dab successful the mediate of a analyzable Git cognition, lone to beryllium stopped asleep successful your tracks by the dreaded communication: “β¦38c74d is a merge however nary -m action was fixed”? This irritating mistake, frequently encountered once utilizing git cherry-choice, tin convey your workflow to a screeching halt. Knowing wherefore this occurs and figuring out however to hole it is important for immoderate developer running with Git. This article volition delve into the intricacies of this mistake, offering broad explanations and actionable options to acquire you backmost connected path.
Knowing the “β¦is a merge however nary -m action was fixed” Mistake
This mistake arises once you effort to cherry-choice a merge perpetrate. A merge perpetrate, dissimilar a daily perpetrate, has 2 oregon much genitor commits, representing the branches being merged. Git wants to cognize which genitor’s adjustments to use throughout the cherry-choice, and the -m action is however you archer it. With out the -m action, Git is near confused, uncertain which lineage to travel, therefore the mistake communication.
Ideate attempting to merge 2 highways into 1 with out specifying which lane to travel. Chaos would ensue! Likewise, Git wants broad directions once dealing with merge commits.
This content often seems once attempting to isolate circumstantial modifications from a merged characteristic subdivision. Realizing however to resoluteness it is indispensable for businesslike codification direction.
Resolving the Mistake with the -m Action
The resolution is fortunately easy. Once cherry-choosing a merge perpetrate (e.g., 38c74d), usage the -m action adopted by the genitor figure (1 oregon 2, and typically much) you want to use. The genitor figure signifies which subdivision’s modifications to incorporated. The archetypal genitor (genitor 1) is sometimes the subdivision you merged into, and the 2nd genitor (genitor 2) is the subdivision you merged from.
For case, to use the adjustments from the 2nd genitor, you would usage:
git cherry-choice -m 2 38c74d
This bid tells Git to use the adjustments launched by the 2nd genitor of the merge perpetrate.
- Ever treble-cheque the genitor figure earlier executing the bid.
- Utilizing git log -p 38c74d tin aid visualize the modifications launched by all genitor.
Alternate Approaches: Rebasing and Patching
Piece the -m action is the about nonstop resolution, alternate options be, similar rebasing oregon patching. Rebasing tin linearize your past by replaying commits connected apical of different subdivision, possibly avoiding merge commits altogether. Patching includes extracting the modifications from a perpetrate and making use of them elsewhere. Nevertheless, these strategies are mostly much analyzable and necessitate a deeper knowing of Git.
See these alternate options once dealing with much intricate eventualities oregon once avoiding merge commits is a precedence.
Selecting the correct attack relies upon connected the circumstantial discourse and your comfortableness flat with Gitβs precocious options.
Stopping the Mistake: Champion Practices
Adopting proactive methods tin reduce the incidence of this mistake. Squashing commits earlier merging tin trim the figure of merge commits, simplifying your past. Broad connection inside your improvement squad astir merging methods is besides important.
Found a accordant workflow, possibly favoring rebasing complete merging once due, to keep a cleaner Git past.
- See squashing commits earlier merging.
- Pass merging methods with your squad.
- Research rebasing arsenic an alternate to merging wherever relevant.
By implementing these champion practices, you tin streamline your Git workflow and decrease irritating interruptions.

FAQ
Q: What if I don’t cognize which genitor to take?
A: Analyze the modifications launched by all genitor utilizing git entertainment 38c74d^1 and git entertainment 38c74d^2. This volition aid you realize the variations and take the accurate genitor.

Question & Answer :
I made any modifications successful my maestro subdivision and privation to carry these upstream. Once I cherry-choice the pursuing commits. Nevertheless, I acquire caught connected fd9f578 wherever git says:
$ git cherry-choice fd9f578 deadly: Perpetrate fd9f57850f6b94b7906e5bbe51a0d75bf638c74d is a merge however nary -m action was fixed.
What is git attempting to archer maine and is cherry-choice the correct happening to beryllium utilizing present? The maestro subdivision does see modifications to information which person been modified successful the upstream subdivision, truthful I’m certain location volition beryllium any merge conflicts however these aren’t excessively atrocious to straighten retired. I cognize which adjustments are wanted wherever.
These are the commits I privation to deliver upstream.

The manner a cherry-choice plant is by taking the diff a changeset represents (the quality betwixt the running actor astatine that component and the running actor of its genitor), and making use of it to your actual subdivision.
Truthful, if a perpetrate has 2 oregon much mother and father, it besides represents 2 oregon much diffs - which 1 ought to beryllium utilized?
You’re attempting to cherry choice fd9f578, which was a merge with 2 dad and mom. Truthful you demand to archer the cherry-choice bid which 1 in opposition to which the diff ought to beryllium calculated, by utilizing the -m action. For illustration, git cherry-choice -m 1 fd9f578 to usage genitor 1 arsenic the basal.
Genitor 1 is the “archetypal genitor”, 2 is the “2nd genitor”, and truthful connected. The command is the 1 successful which they’re listed successful the perpetrate (arsenic seen by git entertainment and the similar).
I tin’t opportunity for certain for your peculiar occupation, however utilizing git merge alternatively of git cherry-choice is mostly advisable. Once you cherry-choice a merge perpetrate, it collapses each the modifications made successful the genitor you didn’t specify to -m into that 1 perpetrate. You suffer each their past, and glom unneurotic each their diffs. Your call.
