Getting Started Creating an App fails to build

[wcwynn]

Following the getting started guide and creating an app, the created app fails to build. There appears to be a missing Skip output folder (or the folder is located in the wrong location).

Missing directory and files

It seems the Android/settings.gradle.kts is expecting a directory to be located in one location when it is actually present in a different location:

Thanks for the detailed report. If you perform a clean rebuild, can you let us know if you get the same error? This has been an intermittent issue with Xcode 15 where the plugins are sometimes executed in the wrong order, and it usually goes away with a clean rebuild.

(For the record, the incorrect directory reference skip-unit.output/SkipUnit/destination/skipstone versus skip-unit.output/SkipUnit/skipstone is likely not the issue; the plugin output folders changed in Xcode 16, which means we have to check both – the error message is just referencing the final location checked, but it would have checked both locations and succeeded if either were found)

I tried a clean rebuild a few times but received the same error. I also completely removed the skip-tools-eval directory and tried again from scratch but unfortunately received the same error.

[marcprux]

How about running Xcode's File/Packages/Reset Package Caches and then doing a clean re-build?

Also, did the skip init command pass? That also tried to build the project, so if it passed and Xcode is failing, then something is amiss. If you open the Terminal and cd to the package folder and run skip export, does it pass? If not, can you post the failure log?

Unfortunately, this did not resolve the problem.

Also, did the skip init command pass?

Yes, it seemed to pass.

If you open the Terminal and cd to the package folder and run skip export, does it pass?

Yes, it seemed to pass.

Hmm. Very odd.

Can you try checking out the default "Hello" sample app from https://github.com/skiptools/skipapp-hello and opening that in Xcode and seeing if that builds? If not, can you post the complete gradle error log?

[wcwynn]

I received the same build error for the "Hello" sample app.

I noticed in both projects the plugins is showing in red (see image).

[marcprux]

Can you post the complete skip-gradle.log.txt file from when it fails (either your own project or the Hello sample)? There might be other warnings or errors in there that indicate what went wrong…

[wcwynn]

Please see the details of my previous message and original issue description for the skip-gradle.log.txt files. I think they are complete but if there is another file you're expecting just let me know.

[marcprux]

I see the excerpt of the skip-gradle.log.txt file that you posted, but I'd like to see the entire file in order to see if it contains any earlier errors or warnings. Can you attach it to this issue? You should be able to command-click on it and open it in the Finder to get the file reference.

[wcwynn]

Here are the files using the file reference from Finder (following your instructions). skip-gradle.log.txt skip-gradle.log.txt

@marcprux any news here? having same issue, when trying to build it throws

[marcprux]

@luisBoost I think this is a different issue: that "skipstone" is disabled error just means that the plugin has not been approved by you. You should have seen a dialog box asking for permission to run the plugin when you tried to build the project. If you clean the build and re-start Xcode and open the project again, do you get the dialog?

@marcprux Thanks for the quick response, im not seeing the dialog, I know which one it is. but have been trying to get it to show and nothing, it just fails immediately after tapping the build button. have tried to remove derived data, a deep clean, reset the packages and no luck

[luisBoost]

after restarting the Mac, I was able to see the "enable" button to show the modal after trying to build, thanks
