"Mergetool path issue" when launching external merge tool (OSX)

[Bradley Kent]

When I choose "Launch external merge tool" I get

Mergetool path issue

Current path:/Library/Developer/CommandLineTools

Please set the command tool path in Xcode and Try again!

I don't know what this means or how to fix

External diff tool works fine

I have Sourcetree 4.1.3

xcode-select --print-path

displays
/Library/Developer/CommandLineTools

(same path referred to in error message)

I tried

sudo rm -rf /Library/Developer/CommandLineTools

 Sourcetree immediately prompted me to instal Xcode.  Which I did.

Still get the error

Reverting to Sourcetree 4.1.2  (or 4.1.1) solved issue

[mikepearce · Accepted solution]

Solved for me by ensuring Command Line Tools were set correctly in Xcode (Preferences->Locations).

For some reason this was not set.

[Ryan D LaBarre]

Thank you, this did the trick for me as well.

[erikpallhansen]

@mikepearce Doing this and restarting SourceTree did the trick for me. Thanks!

[Brandon LaCava]

Worked for me, v4.1.5

[Alexey.Egorov@lampenwelt.de]

So, maybe the issue is coming when Xcode is not installed? I only have the command line tools installed. Downgrade to 4.1.1. worked out for me. I kinda don't want to install Xcode as I don't use it at all.

[mithun.chaubey]

This worked for me on 4.1.8. Unfortunate for people who don't want to install Xcode though :-/

[Mahadeb Raj Bangshe]

Awesome! It works for me.

To set up Command Line Tools in Xcode, follow these steps:

1. Open Xcode on your Mac.
2. Go to the menu bar and click on "Xcode" and then select "Preferences".
3. In the preferences window, click on the "Locations" tab.
4. Look for "Command Line Tools" and click on the drop-down menu next to it.
5. Select the version of the Command Line Tools that you want to use.
6. If the version you want is not listed, click on the "Download" button to download and install it.
7. Once you have selected the Command Line Tools version, close the preferences window.

That's it! You have now set up Command Line Tools in Xcode. You can now use the command line tools in Terminal or in Xcode.

Reverting to 4.1.1 fixed this for me.

Reverting to 4.1.2 fixed the problem also on my side.

Not being able to launch my KDiff3 merge tool to resolve conflicts is is a big problem for me. Downgrading to 4.1.2 as suggested above fixed it for me.

@Bradley Kent  Did you install Xcode? If yes, then could you please check the Xcode tool path using this command "xcode-select --print-path". Also, Could you please share the system information?

[Hussam Radwan]

same problem occurred for me using sourcetree version 4.1.3 (239)

for command "xcode-select --print-path"
printed "/Library/Developer/CommandLineTools"

system information "uname -a"

This is a bug, here is the ticket, as pointed out in other answers: https://jira.atlassian.com/browse/SRCTREE-7737

The bug is finally fixed in 4.2.0, build date 24-Aug-2022 (see https://www.sourcetreeapp.com/download-archives).

Installing Xcode is not a viable workaround, as xcode shouldn't be a required dependency for sourcetree. I do not have xcode installed, I confirmed the issue is resolved in 4.2.0. For anybody still stumbling on this issue, upgrade to 4.2.0, should do the trick.

[vmpj]

I still got the same issue on 4.2.0. Downgrading to 4.1.2 also did not help.

Only fiddling with location settings in XCode, as described here, fixed it for me.

[Adam O_Dwyer]

Same issue in 4.1.7.

I do not have Xcode installed.

Searching Sourcetree docs for "requirements", "xcode" gives no results.

[michael_rarela]

Hmmm... this bug has existed for ~5 months.  SourceTree doesn't seem to receive bug fixes quickly.  Going to explore Fork instead.

[michael_rarela]

Fork is working well for me.  But since I like the "Reverse Hunk" feature of SourceTree, I thought I'd give it another shot.

I was not successful with v4.1.6. (sadness).  Anyone else explore v4.1.6?

[rufwork]

Okay, normally I hate these "Fix my bug or I'm out of here!" posts, especially for free (if not Free) software, but I might make an exception this time. ;) 

With Fork, you can collapse all merge commits and only display those you need right now. Collapse all branches using the context menu of the graph and expand the ones you’d like to keep.

Hellll-low nice. I was just complaining about not being to do this today.

(Dirty secret: On Windows, I still use SourceTree v1.7 precisely to avoid these sorts of overly common dealbreaking bugs. I've yet to regret it.)

[Jerry Guo]

Same issue here with 4.1.3

[pix]

I have exactly the same issue.. on 4.1.3

[mikepearce]

Same issue here with 4.1.3

[Roberto Gonzalez]

I reinstalled xcode tools and I'm facing the same issue.

[Paul Li]

Downgrade to 4.1.1 fixed the issue for me.

[Sourigna Phetsarath]

Has this been resolved in the latest release?  Still seems to be an issue.

[Bob Hatcher]

This worked for me:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

[Joe Page]

same issue on version 4.5.1 (241)

I had it working fine before but can't get my merge tool to work with my new Mac

[rufwork]

4.1.5 (rather than 4.5.1)?

[Alfonso Martin]

I guess this issue is the same as reported here?
https://jira.atlassian.com/browse/SRCTREE-7737

[Giancarlo Espinosa]

Same problem here. I reinsetalled XCode and command line tools and now having the same issue. 

[Giancarlo Espinosa]

Downgrading to 4.1.2 fixed it for me.
