intellij idea : how to debug a java:fx maven project?

Question

I have a old javafx application that I have to run by doing mvn javafx:run but now I would like to debug it with intellij idea.

If I debug the configuration I use to run it, the debugger is connected but it doesn't stop at any breakpoint.

If I try to run a mvn command like mvn -Dmaven.surefire.debug="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=6666" javafx:run and connect with the remote I get this error (from the debugger):

java.util.ServiceConfigurationError: com.sun.jdi.connect.Connector: Provider

sun.jvm.hotspot.jdi.SACoreAttachingConnector not found java.util.ServiceConfigurationError: com.sun.jdi.connect.Connector: Provider

sun.jvm.hotspot.jdi.SADebugServerAttachingConnector not found java.util.ServiceConfigurationError: com.sun.jdi.connect.Connector: Provider

sun.jvm.hotspot.jdi.SAPIDAttachingConnector not found

sa-jdwp server connected

I am not sure what I need to do to be able to debug it.

Answer 1

I found a way to make debugging work by creating a debug execution in the pom.xml and then using intellij idea to remote debug it.

I so now I can run: mvn clean javafx:run@debug

The new build of my pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <version>0.0.3</version>
            <executions>
                <execution>
                    <id>run</id>
                    <configuration>
                        <mainClass>project.Main</mainClass>
                    </configuration>
                </execution>
                <execution>
                    <id>debug</id>
                    <configuration>
                        <mainClass>project.Main</mainClass>
                        <options>
                            <option>-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:8000</option>
                        </options>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
