Null pointer exception when launching as Javascript if analyzer is off #14969
Description
The 'Run as Javascript' option fails when running it on an .html file that is under a folder that has been marked as "Don't analyze".
I run into this playing with a polymer app. The app was built with 'pub-build' and the 'build/' folder contained many files with warnings that I wanted to temporarily disable (the extra warnings are another issue that will be fixed in the app and/or polymer). Then I tried calling 'Run as Javascript' in an .html file in that folder and run into this.
Here is a simple repro:
- create a new web-application project called 'app' using the wizard (honestly, the contents of the .html file don't seem to matter, just an empty html file with a script tag would do)
- right-click on 'web/' and select Don't Analyze
- right click on app.html and select 'Run as Javascript'
Then you get an exception like this:
