Gradle clean task fails in gradle [version 5.6.4 and 6.0.1]

[netbeansuser2019]

Seems that from version 5.4 (e.g. 5.2.1 seems OK), but properly tested with 5.6.4 and 6.0.1.

Gradle: 5.6.4 for wrapped 6.0.1
JVM: 11.0.2 (Oracle Corporation 11.0.2+9)
IDE: Netbeans 11.2

Expected Behavior

Use prior proper handling of file-existence-checking or locking so do not fail in IDE clean task or at least report that as warn not as error (so do not stop cleaning of subproject) especially as build directory is deleted after this task.

Current Behavior

When it is executed "clean" task build is failed and you have to run possibly even N-times a clean task about each subproject that you have under root. But the build directory is deleted after execution such "clean" task.

Context

IDE: Netbeans 11.2
Task: clean
Clean all by one call not failing all the time and no need to run N-times.

Steps to Reproduce

1. create root and subproject, but I think that I can see it wven with just simple new Netbeans gradle project.
2. use listed version e.g. 5.6.4 via wrapper
3. use IDE to clean that uses such wrapper to execute "clean"

I miss there attach so I put herein at least build.gradle:

---

apply plugin: 'base'
apply plugin: 'java'
apply plugin: 'distribution'
apply plugin: 'application'
apply plugin: 'com.jfrog.artifactory'
apply plugin: 'eclipse'

buildscript {
repositories {
mavenCentral()
jcenter()
maven { url 'https://oss.jfrog.org/artifactory/oss-snapshot-local' }
maven { url 'https://plugins.gradle.org/m2/' }
}

dependencies {
    classpath 'org.jfrog.buildinfo:build-info-extractor-gradle:4.11.0'        
}

}

mainClassName = 'sandbox2.Main'

group = 'snadbox'
version = '3.0.0.0.SNAPSHOT'
sourceCompatibility='11'
targetCompatibility="${sourceCompatibility}"

if ("${gradle.gradleVersion}" != "5.6.4") {
logger.error("ERROR (Gradle ${gradle.gradleVersion}): Build script is not done for your version of Gradle, you have to use 5.6.4.")
}

repositories {
mavenCentral()
jcenter()

maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }

}

configurations {
compileOnly {
extendsFrom annotationProcessor
}
}

dependencies {
annotationProcessor 'org.projectlombok:lombok:1.18.10'
testCompile 'junit:junit:4.12'
}

Your Environment

Seems that it was IDE issue and seems fix in Netbeans 11.3
