Task List

• [x] Steps to reproduce provided
• [x] Stacktrace (if present) provided
• [x] Example that reproduces the problem uploaded to Github
• [x] Full description of the issue provided (see below)

Steps to Reproduce

1. With Micronaut version 1.1.4 on macOS run mn create-app myapp --features file-watch.
2. Run ./gradlew run --continuous.
3. Visit the /hello route and note what response you got.
4. Change the string returned from function index in the src/main/java/myapp/HelloController.java file and save the file.
5. After a moment, visit the /hello route and see that the response hasn't changed.

Expected Behaviour

The server should be stopped so that Gradle can rebuild and restart the application.

Actual Behaviour

$ ./gradlew run --continuous

> Task :compileJava
Note: Creating bean classes for 1 type elements

> Task :run
23:46:58.577 [main] INFO  io.micronaut.runtime.Micronaut - Startup completed in 730ms. Server Running: http://localhost:8080
<=========----> 75% EXECUTING [32s]
> :run

At this point (at 75%) Gradle hangs and never gets to restart.

This was fixed by https://github.com/micronaut-projects/micronaut-core/commit/e4f1431a2746628593910853cdf6675bb47c9978 if you are willing to use 1.2 RC2

In the meantime I have backported the fix. Thanks for the report.

Broken again for Micronaut 1.2.0 and Gradle 5.5?
Simple test with ./gradlew run --continuous does not detect changes in source files.

This seems to still be an issue. Micronaut 1.3.0
