Declaring a custom "clean" task when using standard Gradle lifecycle plugins is prohibited
I am adding the library to jCenter, so for this I need to add some plugins to the build.gradle file of the project. However, I am getting the error
Declaring a custom "clean" task when using standard Gradle lifecycle plugins is not allowed.
I see the block task clean
and when I delete it the error goes away. I guess that's all I need to do, but has it done anything important before? If I ever remove plugins and forget to add a block clean
, what are the dire consequences in the store?
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
plugins {
id "com.jfrog.bintray" version "1.7.3"
id "com.github.dcendents.android-maven" version "1.5"
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

You should not try to override the default job clean
, but instead tweak it to remove additional files such as
clean {
delete rootProject.buildDir
}
But first check if this is the default clean task behavior.
Alternatively, if you want to be able to do a separate clean action individually, you can also define a separate task and add a dependency like
task customClean(type: Delete) {
delete rootProject.buildDir
}
clean.dependsOn customClean

I had this same problem, unfortunately for me I put it task clean
in the wrong place. I had this:
allprojects {
repositories {
google()
jcenter()
mavenCentral()
}
tasks.withType(JavaCompile) {
sourceCompatibility = "1.8"
targetCompatibility = "1.8"
}
task clean(type: Delete) {
delete rootProject.buildDir
}
}
It should be as follows:
allprojects {
repositories {
google()
jcenter()
mavenCentral()
}
tasks.withType(JavaCompile) {
sourceCompatibility = "1.8"
targetCompatibility = "1.8"
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
source to share
In the above code:
allprojects {
repositories {
google()
jcenter()
mavenCentral()
}
tasks.withType(JavaCompile) {
sourceCompatibility = "1.8"
targetCompatibility = "1.8"
}
task clean(type: Delete) {
delete rootProject.buildDir
}
}
replace task clean
with task delete
then it will work:
allprojects {
repositories {
google()
jcenter()
mavenCentral()
}
tasks.withType(JavaCompile) {
sourceCompatibility = "1.8"
targetCompatibility = "1.8"
}
task delete(type: Delete) {
delete rootProject.buildDir'
}
}

enter code hereallprojects {
repositories {
google()
jcenter()
maven {
url 'https://maven.google.com'
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
if you've added maven to your build.gradle then check all brackets. The code should be the same as above. This should fix the problem. It is possible that the parentheses are in different places.

6m Ok, I am getting an error in Gradle that it cannot clear the root project file.
: 25 AM Gradle Sync Failed: Declaring a custom "clean" task when using standard Gradle lifecycle plugins is not allowed.
error code info-ide.actionsShowFilePathAction Exit Code 1
Clean triggers nom run clean dependsOn "npmInstall"
In Gradle doc 4.7, the project in the directory where the build is performed is also configured, but only when Gradle is running without any tasks. This way, tasks by default behave correctly when projects are configured on demand.
Config on Demand Gradle 4.6 Android Plugin for Gradle 3.01 or 3.1.0 with Gradle Gradle Properties File org.gradleconfigureondemand = false
So what I did is to comment the task clean and now I am getting an assembly of these words,
I think what happened is that this script works if you created and modified the project. When you upload a project, you didn't create it the first time. Therefore there is no root project path to clean up as it has not been built yet. This results in a crash. When you comment this the first time, you won't get an error.
Here is the code. // Top level build file where you can add configuration options common to all subprojects / modules.
`buildscript {ext.kotlin_version = '1.2.41
ext.support_version = '26.1.0'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
apply plugin: ‘kotlin’
allprojects {
repositories {
google()
jcenter()
}
}
