spring - Does gradle continuous build support SpringBoot?

Question

When I try to run build with gradle with the -t flag:

./gradlew clean build -x test -t

I get prompt line:

Waiting for changes to input files of tasks... (ctrl-d to exit)

but when I try it with bootRun command it doesn't work/appear:

./gradlew clean bootRun -t

Does it work with Spring Boot? (I know about Spring dev tools plugin - 1.3 is not released yet)

Answer 1

andy-wilkinson is correct in his answer : gradle bootRun never completes because some applications run indefinitely. Its well documented in this issue in the grails project.

I've found a way to force bootRun to live reload the application from the command line. The key items here are the gradle daemon and the spring-boot-devtools package.

To get it to live reload you need to have 2 terminals open.

1. gradle build --continuous

   • build --continuous will keep satisfying the initial build request until stopped
   • gradle build --continuous --quiet & 2>1 >/dev/null runs in the background, but you would miss the important build warnings/errors. gradle --stop to stop watching.

2. gradle bootRun

   • Bootrun starts with spring-boot-devtools on classpath, which will detect changes and restart application.
