This might be a Intellij specific problem but;

  1. Include dev tools in pom.xml

  2. Set On Update Action as "Update classes and resources" SpringBoot Application restarts twice on reload when both a class and property files changed

  3. Run application

  4. Change a property file and a class file
  5. Hit "Update" SpringBoot Application restarts twice on reload when both a class and property files changed

Application restarts then restarts again

This looks very similar to https://github.com/spring-projects/spring-boot/issues/12760. Please try configuring a longer quiet period using spring.devtools.restart.quiet-period. The default is 400ms and I suspect there's a more than 400ms gap between resource processing completing and compilation writing new class files.

When i set it to be 1000 then application doesnt start and give error

Caused by: java.lang.IllegalArgumentException: PollInterval must be greater than QuietPeriod

Comment From: snicoll

@arikanorh thanks for trying. The exception message states that poll interval must be higher than the quiet period. Poll interval is 1sec by default so you may have to increase it according to the exception message. The documentation can be helpful as well.
