Quarkus doesn't refresh when resource files are updated

Describe the bug

My project has a set of json configuration files in the resources directory. We’d like Quarkus to restart and load these files when they are updated. Currently, Quarkus sees the file updates but determines that a restart isn’t necessary. We know this because we see the message ‘Files changed but restart not needed’ when we make modifications.

Expected behavior

Quarkus is restarted when any resource file is modified.

Actual behavior

Quarkus is only restarted when certain resources files are modified. Not certain what these files are, but they include banner.txt.

To Reproduce

Steps to reproduce the behavior:

1. Add file fields.json to resources directory
2. Start quarkus
3. Edit fields.json
4. See message "Files changed but restart not needed’

Environment (please complete the following information):

Output of java -version

openjdk 11.0.10

Quarkus version or git rev

1.10.5.Final

Build tool (ie. output of mvnw --version or gradlew --version)

Apache Maven 3.6.3

Additional context

None.

I think this issue may be closed (or renamed) and can be marked as a good-first-issue for our rockstar community contributors 😉

Stupid question maybe but why don’t we reload by default when resources are changed?

I think that historically we’ve chosen this path to minimize the number of resources that can trigger the reload, i.e. not every resource modification requires a reload. Anyway, if we change it now it would be a non-compatible change. So we should be careful here.
