I use javafx-gradle-plugin and want to debug the program with IDEA, but failed

[Gohan]

Is there any debuggable example working for IDEA + gradle ?

Tried the gradle Debug "jfxRun" using IDEA, but not working..

netstat -an | find "5005"
not find the debug server port..

my build.gradle looks like below:

group 'com.baozs.atwork.tools'
version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.1.3'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath group: 'de.dynamicfiles.projects.gradle.plugins', name: 'javafx-gradle-plugin', version: '8.8.2'
    }
}

apply plugin: 'java'
apply plugin: 'kotlin'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}


jar {
    manifest {
        attributes(
                'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
                'Main-Class': 'com.baozs.atwork.tools.QIMSyncTools.app.MainKt'
        )
    }
}

apply plugin: 'javafx-gradle-plugin'
jfx {
    // minimal requirement for jfxJar-task
    // com.baozs.atwork.tools.QIMSyncTools.app.MainKt
    verbose = true
    mainClass = 'com.baozs.atwork.tools.QIMSyncTools.app.MainKt'
    manifestAttributes = new HashMap<String, String>()
    manifestAttributes['Main-Class'] = 'com.baozs.atwork.tools.QIMSyncTools.app.MainKt'

    // minimal requirement for jfxNative-task
    vendor = 'SyncToolsGui'

    jvmArgs = ["-Xdebug", "-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005"]
    launcherArguments = ["-Xdebug", "-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005"]
}

task fatJfxJar(type: Jar) {
    baseName = project.name + '-fat'
    manifest {
        attributes["Main-Class"] = "com.baozs.atwork.tools.QIMSyncTools.app.MainKt"
    }
    from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
}

also tried the demo, not working either:

Hi, you might want to use runJavaParameter for this

jfx {
    runJavaParameter = '-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005'
}

This parameter was introduced to have debug-settings running, but not having this in production outcome.

I'll try it tonight !
It works!

Can't repeat this in my.

build.gradle

group 'ru.mc'
version '1.0'

buildscript {
    dependencies {
        classpath group: 'de.dynamicfiles.projects.gradle.plugins', name: 'javafx-gradle-plugin', version: '8.8.2'
    }

    repositories {
        mavenLocal()
        mavenCentral()
    }
}

apply plugin: 'java'
sourceCompatibility = 1.8

repositories {
    mavenLocal()
    mavenCentral()
}

apply plugin: 'javafx-gradle-plugin'

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

jfx {
    verbose = true
    mainClass = 'ru.mc.ltec.MainClass'
    vendor = 'dev'
    runJavaParameter = '-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005'
}

Set breakpoint (for example to MainClass.launch(args) method) and click Debug for jfxRun task.

Running log

Application starts immediately without stopping.

I need some additional actions about which in the topic was not explicitly mentioned above?

Hi @zvpdev, did you solve this issue?

Hi @FibreFoX when I run debug mode with
runJavaParameter = '-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005'
it's not work (port 5005 isn't open).

But when I run command:
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 -jar project-jfx.jar manually - it opens the port 5005.
