FormatException thrown when running dart with --pause-isolates
I am getting a FormatException, when I run the test using the following command:
OBS_PORT=9292
dart \
--disable-service-auth-codes \
--pause-isolates-on-exit \
--enable_asserts \
--enable-vm-service=$OBS_PORT \
test/all_tests.dart &
The specific failure and call stack can be seen here: https://github.com/mobxjs/mobx.dart/runs/1176730368?check_suite_focus=true#step:6:78
Interestingly, when I run the tests using pub run test, there are no failures. Could you please help in resolving? I am stuck with a very low coverage due to this exception.

Can you dump the contents of your project's .packages file here? It looks like either there's a syntax error in it or a bug in the parser here: https://github.com/dart-lang/package_config/blob/master/lib/packages_file.dart#L12-L65

Thanks! This looks to be the right format. Out of curiosity, which operating system are you running under?
Answering my own question -- OS in the tests is Ubuntu 18.04.5 LTS.
Version of package_config is: 1.9.3 (latest) Version of coverage is: 0.13.11 (released 2020-06-04)
Thanks. Mostly wanted to rule out Windows a line-ending related issue. Dumped the .packages file above into a local file and did a `grep -v ':'' on it and every line appears to contain a colon. The first line is a comment and should be ignored by the check on line 52 and the bail out on line 62.
/cc @pq in case he's got throughts on why we might be getting a syntax error here.
I see a set of package_config-related commits by @jakemac53 here:
- update the Resolver api to use the new package config api
- update to use the real package_config 1.9.0 and fix tests and .packages parsing
- add some tests, fix bug with relative paths
Those were all landed 2020-02-27, so you're running with the full set of those.
Also can you add this to the top of main in your test_all.dart file : print(await Isolate.packageConfig); (you also need to import dart:isolate).
Hi @jakemac53 , I am running on Dart 2.9.2. Here is the package_config.json

What was the result of print(await Isolate.packageConfig);? (did that point you at this package_config.json file)?
It looks to me like this is trying to parse a new style package_config.json file as an old style .packages file. The package_resolver package has been discontinued and if I recall doesn't support the new format.
The latest coverage package as well as test packages do not use package_resolver as far as I can tell, and it is unclear to me where that usage is coming from based on the stack trace...
