.podspec error - source_files` pattern did not match any file

Question

I am integrating one of my github repos (full code here if it helps) with Cocopods, and I get this error when I run pod spec lint.

 -> DropDownMenu (0.0.1)
  - ERROR | [iOS] The `source_files` pattern did not match any file.

This is the relevant code of my .podspec which I believe is causing the problem.

Looking at examples here, here, and here, I have tried the following

s.source_files  = 'Classes/*.{h,m}'
s.source_files  = 'Classes/DropDownMenu.{h,m}'
s.source_files  = 'Classes'
s.source_files  = 'Classes/**/*.{h,m}'

Is my s.source_files field incorrect? Or did I do something wrong with the .podspec? What can I do to fix this?

My problem is similar to this question, however the solution does not work for me (my code is updated on Github).

Answer 1

The problem is that your podspec is referencing a commit that did not yet have the Classes folder,

i.e. this commit doesn't have a classes folder yet https://github.com/kevinrandrup/DropDownMenu/tree/09c9b3d515b78550557eabc0a8542f9f6f2623cf

You can fix this issue by referencing the latest commit, i.e. changing your podspec source to:

s.source       = { :git => "https://github.com/kevinrandrup/DropDownMenu.git", :commit => "0d6761feefccff1f7d8b7c7788ceb8e9cd1314ea" }
s.source_files  = 'Classes/*.{h,m}'

Answer 2

I got this problem after having CocoaPods generate the podspec file automatically for me with version 1.1.0 RC3.

The original line in the Podspec file was:

s.source_files = 'Pod/Classes/**/*'

I fixed it by changing it to:

s.source_files = 'NAME_OF_POD/Classes/**/*'

Answer 3

I used git tag. It worked well for me.

Step 1: Add tag

git tag 1.0.2 && git push origin --tags

Step 2: Set source with tag

s.source       = { :git => "https://github.com/kevinrandrup/DropDownMenu.git", :tag => s.version }
s.source_files  = 'Classes/*.{h,m,swift}'

Pay attention to that your tag must be equal to you pod spec version.
