IntelliJ IDEA debugger skips breakpoints when debugging Maven tests

问题

I am trying to debug Maven tests in IntelliJ IDEA. When I open IDEA's Maven Projects view and right-click on test goal, I get an option to debug it. Clicking it executes this goal but the execution never stops at any breakpoints. What am I missing?

Thanks.

One solution would be to use remote debugging:

configure the surefire plugin: <debugForkedProcess>true</debugForkedProcess>;
run the test (will wait for a remote debugger to connect)
create and run a remote debug configuration in IntelliJ (will hit your breakpoint); the port to connect to is 5005.

Just disable the forked mode - something like this in your pom file (under project/build/plugins section):

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.14</version>
<configuration>
    <forkMode>never</forkMode>
</configuration>
</plugin>

If you're running unit tests with maven failsafe rather than surefire, then debugger will not stop and you have to manually run a failsafe debugger command line and then intellij will be able to stop on the breakpoints. I am unsure if using <forkMode>never</forkMode> option on failsafe solves this issue.

As I describe here: https://github.com/djangofan/maven-failsafe-debug-example

Your sources for the dependencies do not match the binary code. Make sure you're using the same sources.
