Netbeans: How to execute custom gradle task for debugging

We are using custom source set and hence the default gradle tasks "run" and "debug" cant be used from netBeans to launch.

Please let me know the steps to configure Netbeans such that when I clik "Debug Project", I need to execute custom gradle task :-

gradle -PmainClass=xxx.TestDelMe execute

Sample build.gradle with execute task :-

sourceSets {
        java.srcDir 'src/integTest/java'
        resources.srcDir 'src/integTest/resources'

* This task creates the jar for the compiled test code.
task integTestJar (type: Jar) {
    from sourceSets.integTest.output
    appendix = 'integ-tests'
    gradle -PmainClass=xxx.TestDelMe execute
    task execute(type:JavaExec) {
        main = mainClass
        debug = true
        dependsOn 'assemble', 'integTestJar'
        classpath = sourceSets.integTest.runtimeClasspath + sourceSets.integTest.compileClasspath
