IntelliJ IDEA 2017.1 does not stop on breakpoints

Question

I have an old Gradle project that I've opened recently using the new IDEA 2017 and I have just noticed it will not stop on breakpoints anymore (these are active, but not "validated" - no checkmark on them.

The code is run locally (a gradle run/debug config without any options) with bootRun as the gradle task.

I have tried an Invalidate Caches/Restart without any success. I have also tried re-importing the project in IDEA.

A while back I had the same issue after upgrading to Spring 1.4.5 (if I remember correctly). I couldn't figure out why, so I downgraded back to 1.4.2 and everything worked fine. However, this time I'm running Spring 1.2.4 and I cannot upgrade to a newer version without changing some code (and I don't want that yet)

Solution 1

Well... for some reason, creating a Gradle run/debug config would make it connect to the wrong port (something random over 50000) while the application was running on 8080.

Anyway, long story short, creating an Application run/debug config solved the issue and everything works fine now.

Solution 2

Confirm. Problem was that I try to debug using maven run configuration. Switching to Application configuration type helps. I've spend half of a day on it (

Solution 3

I have faced this problem.

1. Invalidate caches and restart
2. I was using Spring Boot rest api project in intellij so all debug breakponts were getting passed/ignored. But the programm started debug process whenI hit Api using postman

Run -> Edit Configuration - Plus -> Application ->Then point to main method

My friend, thank you for sharing, but how do you expect others make full use of your answer if you don't share steps, or more clarification: how exactly do I switch to app mode?!

Hi, I am also facing the same issue. But in my case, the project is an Spring-based project. So how to configure the Application config?

I wish I had found this before I wasted a load of time of trying to maven and spring profiles
