dartanalyzer can't resolve package: URIs unless it's in the dir of the project

[sethladd]

Consider this case:

• create a dummy project (via stagehand package-simple)
• pub get
• cd to your home directory
• run dartanalyzer path/to/dummy/project/bin/main.dart

Expected: analysis to work

Actual:

~ $ dartanalyzer ~/tmp/testpkg/bin/main.dart 
Analyzing [/Users/sethladd/tmp/testpkg/bin/main.dart]...
[error] Target of URI does not exist: 'package:testpkg/testpkg.dart' (/Users/sethladd/tmp/testpkg/bin/main.dart, line 4, col 8)
[warning] Undefined name 'testpkg' (/Users/sethladd/tmp/testpkg/bin/main.dart, line 4, col 42)
[warning] Undefined name 'testpkg' (/Users/sethladd/tmp/testpkg/bin/main.dart, line 8, col 25)
1 error and 2 warnings found.

If I cd into my dummy project, I can analyze:

~ $ cd tmp/testpkg/
~/tmp/testpkg $ dartanalyzer bin/main.dart 
Analyzing [bin/main.dart]...
No issues found

FWIW the VM runs the code from an arbitrary directory

~ $ dart ~/tmp/testpkg/bin/main.dart 
Hello world: 42!

After chatting with @stereotype441 at length yesterday, I'm pretty convinced that getting this right depends on solving the larger issue of proper context creation for enumerated files (https://github.com/dart-lang/analyzer_cli/issues/53) which is gated by the much discussed ContextManager rework (#24133).

How would one work around this with the sublime text 3 dart plugin? Even if I launch sublime from the directory of the project, I get the "target of uri does not exist" error. Doing an analysis via cli command in the project dir works fine.

Oops, turns out I did a pub get as root, but am using sublime as a user, so the files in .pub-cache had permissions preventing the normal user from accessing package files. A chown of those files to the user has fixed the errors for sublime. Sorry for the noise.

This is either solved, or just not a context we plan to support.
