How to Resolve App Engine's 'conflicts with same file imported from GOPATH' Issue?

Appengine "conflicts with same file imported from GOPATH" issue:

This issue arises when Appengine imports files from the root directory (where app.yaml is located), causing conflicts with explicit imports in your code. The problem stems from the duplication of imports.

To resolve this, you have two options:

1. Omit the source repository path in imports:

• Remove the "source repository" part of import paths. For example, instead of importing "github.com/blah/blah," import "blah/blah."
• This approach limits your code to appengine, so consider using build constraints to conditionally include/exclude files based on the target environment (e.g., build !appengine).

2. Separate modules and dependencies into a project:

• Remove all sub-folder packages from the main project (where app.yaml resides) to prevent appengine from scanning them.
• Move them to a separate project (e.g., SampleIssueDeps) that is not a sub-directory.
• Then, import the dependencies using their full path. For instance, import "github.com/MarkHayden/SampleIssueDeps/lib1."

Summary: For sub-folder packages in an Appengine project, you can either omit the "source repository" part of import paths or move all code to separate projects and import them like external dependencies. By doing so, you avoid conflicts caused by duplicate imports.
