There were `pubspec.yaml` files in `tools/` that were not included in the global package config. That means that their imports were irrelevant, which could be misleading. And if any tool would look at the `pubspec.yaml` file, it might be inconsistent with the actual package resolution. Makes every `pubspec.yaml` file either be included by the `tools/generate_package_config.dart` script, or deletes them if they seem to be stale and unused. (Compare vs. `git ls-files '**/pubspec.yaml'`.) Excepted `tools/dart2js/sourceMapViewer/pubspec.yaml`. The entire directory might be stale. The dependencies of that pubspec are not SDK dependencies otherwise, the pubspec has no SDK min-version, which is now a requirement, and the README refers to a *packages directory*. Keeping as-is and filing issue to have owners take a look. Added `lib/` directory to `tools/` to avoid `tools/bots/` being inside the package URI root of the `tools/` package, which would cause its `../../pkg/...` import to fail. Makes every `pubspec.yaml` file use a `^...` SDK constraint instead of the longer `>= ... < ...` format. Tested: No new tests, goal is to keep running the same way Change-Id: I688e463fe985fc4de43550a1f4c7ff350536cffc Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/414020 Commit-Queue: Lasse Nielsen <lrn@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com> Reviewed-by: Sigurd Meldgaard <sigurdm@google.com> Reviewed-by: Brian Quinlan <bquinlan@google.com>
