Maven Debug does not stop at breakpoints

Hi,
I just started using IntelliJ 7.0.3 to try it out.

In the Maven project view, I'm doing right-click Debug on install in the LifeCycle, but it doesn't stop at any of my breakpoints.

In the Debugger view, I get the message:
"Disconnected from the target VM, address: '127.0.0.1:1539', transport: 'socket'

The port is different every time.

I'm using an external MAVEN_HOME and the Maven Runner also uses the external Maven.

The breakpoints are big red dots with red(pink) highlight over the line of code.

Am I using this wrong?

I am having the same problem .   I created  a sample project to demonstrate it:

1. Clone this in your IntelliJ-IDEA (2018) :  https://github.com/djangofan/maven-failsafe-example

2.  Put breakpoint in AppIT.java class

3.  Create a IntelliJ-IDEA Maven run configuration with `clean verify`   and try to run it with Debugger.

4.  You'll notice it doesnt stop on break point.   What am I doing wrong?

 

The reason this happens is that IntelliJ cannot connect to debugger in forked failsafe thread.   So, you need to run maven to start a debugger on port 5005:

mvn -Dmaven.failsafe.debug verify

 

Then, connect IDE debuger to that port.  Then it works.   This was not obvious and tricky to figure out.
