I am making an assumption `OutputMode.none` should _really_ mean
`OutputMode.failuresOnly`, that is, if we ever get a non-zero exit code,
we still want to know why. If I've somehow misunderstood that, LMK and
I'm happy to revert this PR or make adjustments.
This fixes the bug where if you were to do:
```sh
git clone https://github.com/myuser/fork-of-flutter
cd fork-of-flutter
./bin/flutter update-packages
```
You now get:
1. An actual error message, versus no output at all.
2. A warning that a common reason is not tracking a remote, with
instructions to fix it.
Closes https://github.com/flutter/flutter/issues/148569.
â¦and removed the no-shuffle tag.
This PR fixes#142376 by fixing the flaky test in language_version_test.dart and removes the no-shuffle tag.
Â
## The Problem
The test expected the language version that is set at the top of the test file ('2.13' set in language_version_test.dart â line 14) but defaulted to the language version set in the file it is testing ('2.12' is set in language_version.dart).
This problem was hidden when some other test ran before this test and set up the language version correctly.
Â
## The Fix
Make the test itself load the default language version we are testing against.
Add a new `BuildTargets` class that provides commonly used build targets. And avoid importing files from `build_system/targets` except from the top level entrypoints or from top level commands.
Also move `scene_importer.dart` and `shader_compiler.dart` into `build_system/tools` because they are not `Target` classes, but wrapper for certain tools.
With this change, we can ignore all files in `build_system/targets` internally and make PR #142709 easier to land internally. See cl/603434066 for the corresponding internal change.

Also note that I have opted to add a new variable in `globals.dart` for `BuildTargets` in this PR, but I know that we are trying to get rid of globals. Several alternatives that I was considering:
1. Add a new field in `BuildSystem` that returns a `BuildTargets` instance. Since `BuildSystem` is already in `globals`, we can access build targets using `globals.buildSystem.buildTargets` without adding a new global variable.
2. Properly inject the `BuildTargetsImpl` instance from the top level `executable.dart` and top level commands.
Let me know if you want me to do one of the above instead. Thanks!
Part of work on [#101077](https://github.com/flutter/flutter/pull/141194). This is done as a separate PR to avoid a massive diff.
## Context
1. The `FakeCommand` class accepts a list of patterns that's used to match a command given to its `FakeProcessManager`. Since `FakeCommand` can match a list of patterns, not just specifically strings, it can be used to match commands where the exact value of some arguments can't (easily) known ahead of time. For example, a part of the tool may invoke a command with an argument that is the path of a temporarily file that has a randomly-generated basename.
2. The `FakeCommand` class provides on `onRun` parameter, which is a callback that is run when the `FakeProcessManager` runs a command that matches the `FakeCommand` in question.
## Issue
In the event that a `FakeCommand` is constructed using patterns, the test code can't know the exact values used for arguments in the command. This PR proposes changing the type of `onRun` from `VoidCallback?` to `void Function(List<String>)?`. When run, the value `List<String>` parameter will be the full command that the `FakeCommand` matched.
Example:
```dart
FakeCommand(
command: <Pattern>[
artifacts.getArtifactPath(Artifact.engineDartBinary),
'run',
'vector_graphics_compiler',
RegExp(r'--input=/.*\.temp'),
RegExp(r'--output=/.*\.temp'),
],
onRun: (List<String> command) {
final outputPath = (() {
// code to parse `--output` from `command`
})();
testFileSystem.file(outputPath).createSync(recursive: true);
},
)
```
Use the pub cache resolved by pub itself.
To add packages to the flutter.zip download they are packaged as tar.gz and added to the pub-cache on first run by using `pub cache preload`.

* Fix issue where ErrorHandlingProcessManager does not forward "mode" parameter to backing ProcessManager's "start" method
* Make "pub get" use ProcessStartMode.inheritStdio instead of forwarding bytes to stdout and stderr
* Fix tests
* Remove unused env var
* Add back 'Running "flutter pub get"...' status log
* Fix indent

* Use `dart __deprecated_pub` instead of `pub` to invoke pub from tools
The top level `pub` commmand has been deprecated and will print
a message. It is however implemented via the __deprecated_pub command
that prints no message.
