I wanted to create a pom.xml with Gradle.
But it failed.

Here my build.gradle (project)

   // Top-level build file where you can add configuration options common      to all sub-projects/modules.

buildscript {

repositories {

    google()

    jcenter()

}

dependencies {

    classpath 'com.android.tools.build:gradle:3.2.1'

    classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'



    // NOTE: Do not place your application dependencies here; they belong

    // in the individual module build.gradle files

}

}



allprojects {

repositories {

    google()

    jcenter()

}

}



task clean(type: Delete) {

delete rootProject.buildDir

}



task writeNewPom {

doLast {

    pom {

        project {

            inceptionYear '2008'

            licenses {

                license {

                    name 'The Apache Software License, Version 2.0'

                    url 'http://www.apache.org/licenses/LICENSE-2.0.txt'

                    distribution 'repo'

                }

            }

        }

    }.writeTo("$buildDir/pom.xml")

}

}

and my build.gradle (module)

apply plugin: 'com.android.application'



apply plugin: 'com.github.dcendents.android-maven'

group = 'com.github.ludev-studio'



apply plugin: 'maven'



android {

compileSdkVersion 28

defaultConfig {

    applicationId "com.ludevstudio.colorpicker"

    minSdkVersion 15

    targetSdkVersion 28

    versionCode 1

    versionName "1.0"

}

buildTypes {

    release {

        minifyEnabled false

        proguardFiles getDefaultProguardFile('proguard-     android.txt'), 'proguard-rules.pro'

    }

}

buildToolsVersion '28.0.3'

}



dependencies {

implementation fileTree(include: ['*.jar'], dir: 'libs')

implementation 'com.android.support:appcompat-v7:28.0.0'

testImplementation 'junit:junit:4.12'

implementation project(':colorpicker')

}

this is the output, then I executet the writeNewPom Task with the gradlew.bat:

FAILURE: Build failed with an exception.



* Where:

Build     file 'C:UserslucadDocumentsprogrammierungProjekteJavaAndroidlibrariesColo    rpickerbuild.gradle' line: 32



* What went wrong:

Execution failed for task ':writeNewPom'.

> Could not find method pom() for arguments [build_1nb7g16o7col6erw9g4aech65     $_run_closure3$_closure5  $_closure6@30d7b2ef] on task ':writeNewPom' of type org.gradle.api.DefaultTask.

Run with --info or --debug option to get more log output. Run with --scan to     get full insights.



* Exception is:

BUILD FAILED in 8s

1 actionable task: 1 executed

I red something about missing maven plugin, but like you can see in my gradle.build, I added the plugin.
So, what to do?

From your trace

Caused by:     org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method pom() for arguments [build_1nb7g16o7col6erw9g4aech65$_run_closure3$_closure5$_closure6@30d7b2ef] on task ':writeNewPom' of type org.gradle.api.DefaultTask.

Gradle couldn't find any suitable type to delegate the pom() method to, thats because you forgot

apply plugin: 'maven'

in your projectbuild.gradle. Just put the above line in your project build.gradle and it'll all be good.
