Maven-publish cannot not apply withXML on pom file (No signature of method)

Question

Ok, so I am having the exact issue as described here:

Android library dependencies missing from POM with Gradle

I copied the provided answer to my gradle file as follows:

publishing {
    publications {
        mavenAar(MavenPublication) {
            groupId group
            artifactId 'exampleId'
            version version
            artifact source: file('build/outputs/aar/example-release.aar')

            //The publication doesn't know about our dependencies, so we have to manually add them to the pom
            pom.withXml {
                // for dependencies and exclusions
                def dependenciesNode = asNode().appendNode('dependencies')
                configurations.compile.allDependencies.each { ModuleDependency dp ->
                    def dependencyNode = dependenciesNode.appendNode('dependency')
                    dependencyNode.appendNode('groupId', dp.group)
                    dependencyNode.appendNode('artifactId', dp.name)
                    dependencyNode.appendNode('version', dp.version)

                    // for exclusions
                    if (dp.excludeRules.size() > 0) {
                        def exclusions = dependencyNode.appendNode('exclusions')
                        dp.excludeRules.each { ExcludeRule ex ->
                            def exclusion = exclusions.appendNode('exclusion')
                            exclusion.appendNode('groupId', ex.group)
                            exclusion.appendNode('artifactId', ex.module)
                        }
                    }
                }
            }
        }
    }
    repositories {
        mavenLocal()
        maven {
            url  selectDeploymentURL()
            if ( project.hasProperty( 'nexusUser' ) ) {
                credentials {
                    username project.getProperty('nexusUser')
                    password project.getProperty('password')
                }
            }
        }
    }
}

However I am getting an error when attempting to publishToMavenLocal, and I'm not sure why?

FAILURE: Build failed with an exception.

Build file 'path/build.gradle' line: 136

Answer 1

So as Karma has it, I found the answer shortly after posting

I just removed the ModuleDependency dp and referred to everything from it, and it got past this error, I see the new nodes in the pom file now.

configurations.compile.allDependencies.each {
    def dependencyNode = dependenciesNode.appendNode('dependency')
    dependencyNode.appendNode('groupId', it.group)
    dependencyNode.appendNode('artifactId', it.name)
    dependencyNode.appendNode('version', it.version)
