Description

From #1896 (comment):

this [the symbol-not-indexed problem] is happening again, but this time I have a simple repro.

Create a new package plugin:

swift package init --type command-plugin --disable-xctest --enable-swift-testing

Go to the file in the Plugins folder. Observe context's type is not indexed and all:

This is with "backgroundPreparationMode": "enabled".

@ahoppen commented (#1896 (comment)):

That’s a different issue. It’s because you the package isn’t buildable in this state either. If you try to build, you get

error: The package does not contain a buildable target.
Add at least one `.target` or `.executableTarget` to your `Package.swift`.

Steps to Reproduce

See above.
