fix: Jaspr Build Fail On New Project

[mcmah309]

Description

Jaspr fails when trying to start a new project in a container. The issue was not observed outside a container.

Output

The below output was run inside a container. Based on the below output, does jaspr build currently fail if there is any stderr output from flutter? Running as root is common in containers and the message from flutter is expected. Other than that, nothing useful from --verbose. This is my usual flutter dev environment I always use.

root@c-nixos:/workspaces/voyver_website (jaspr)$ jaspr create voyver_website

This isn't really something jaspr can control I think cause it needs to run flutter for certain things.
The proper solution would be to create a non-root user.

If you don't need flutter plugin support, you can also select 'No' for "Enable support for using Flutter web plugins in your project? (Y/n)", which should workaround that.

[mcmah309]

Just to clarify, Flutter runs fine in my container. It's just that warning message is expected. My only thought was, maybe Jaspr is failing because it gets a message on stderr, then that is something Jaspr can fix. If this is not the case, then this is still a bug as I expect Jaspr to work since this environment has everything Jaspr should need.

[schultek]

Ah thanks for clarifying. That could be the case.

To make it easier for me to debug, can you run 'dart run build_runnrr build' instead of jaspr build and see of it also fails?

[mcmah309]

Sure

This does seem to be the case

Checking exit code may be a better idea

I'm also running into this when trying to build/deploy my website
