        message = "Oops, you came across a limitation of cocoapods-xlbuild.

The plugin requires that one pod should have ONLY ONE target in the 'Pod.xcodeproj'. There are mainly 2 situations \
causing this problem:

1. One pod integrates in 2 or more different platforms' targets. e.g.
    ```
    target 'iphoneApp' do
      pod 'A', :xlbuild => true
    end
    target 'watchApp' do
      pod 'A'
    end
    ```

2. Use different subspecs in multiple targets. e.g.
    ```
    target 'iphoneApp' do
      pod 'A/core'
      pod 'A/network'
    end
    target 'iphoneAppTest' do
      pod 'A/core'
    end
    ```

Related pods: #{names}, target names: #{raw_names}
