How do I debug a gradle/Spring-boot app in IntelliJ Idea ?

(Ronald Pomeroy) #1

I have a vaadin+spring-boot+gradle app in development and I’m struggling with setting up debugging in IntelliJ Idea.

The project is at

Any help or advice is greatly appreciated.

Can you elaborate on how the question is related to Gradle? Typically, Gradle isn’t involved in running a debugging session from IntelliJ. You could make Gradle generate the IntelliJ debug configuration, but to do so, you’ll first have to figure out how to do it manually.

I managed to debug a Spring Boot application run with Gradle as a remote app in IntelliJ Idea. It’s not a very complicated setup, I just had to pass in additional JVM parameters when running the application with Gradle if I recall (and of course set up the remote debugging configuration in Idea). I know I’d also cry tears of joy if there was a more productive way of achieving that, but I think this is an issue between Jetbrains and Spring, not really a Gradle issue.

For the OP and anyone looking for a way to debug a Spring Boot application run with Gradle, as seen at

Add this to your build.gradle file:

applicationDefaultJvmArgs = [

“-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005” ]

In IntelliJ Idea, setup a new Debug configuration and in the options select “Remote”. The defaults should be fine, but pay attention to the port number and transport type (“socket”). Have fun!
