unable to resolve class MavenDeployment after updating the gradle wrapper

Issue

Android Studio offered me to update the gradle wrapper and I accepted.

After the update process it updated the wrapper to the version 7.0.2.

Now I'm getting the following error on my project:

unable to resolve class MavenDeployment 
        @ line 30, column 34.
        beforeDeployment { MavenDeployment deployment -> signing.signPom(deployment) }
        ^
        1 error

It is a library project and I'm using the following guide (and script) for publishing it on MavenCentral: simple library publishing with Gradle

It seems it is no longer resolving the class MavenDeployment from the maven plugin:

apply plugin: 'maven'

Exatly at this point on the script:

afterEvaluate { project ->
    uploadArchives {
            repositories {
                    mavenDeployer {
                            beforeDeployment { MavenDeployment deployment -> signing.signPom(deployment) }
...

I'm not a gradle expert. How can I resolve this error?

Solution

Finally identified the problem: The old maven plugin is deprecated in the new gradle versions.

If you are experiencing this error you need to rewrite your script to use Maven Publish Plugin
