Unable to publish a gradle Jar artifact to a sonatype repository - maven

Question

I am following instructions in the Sonatype documentation for publishing a gradle project.
I have the following gradle version.
$ ./gradlew --version
------------------------------------------------------------
Gradle 7.6
------------------------------------------------------------
Build time: 2022-11-25 13:35:10 UTC
Revision: daece9dbc5b79370cc8e4fd6fe4b2cd400e150a8
Kotlin: 1.7.10
Groovy: 3.0.13
Ant: Apache Ant(TM) version 1.10.11 compiled on July 10 2021
JVM: 1.8.0_181 (Oracle Corporation 25.181-b13)
OS: Mac OS X 10.16 x86_64
When I try to use the uploadArchives task as given in their example, I get the following error:
$ ./gradlew uploadArchives
FAILURE: Build failed with an exception.
* Where:
Build file '/Users/ferozed/stash/libs/mask-json-field-transform/build.gradle' line: 167
* What went wrong:
A problem occurred evaluating root project 'mask-json-field-transform'.
> Could not find method uploadArchives() for arguments [build_6yphclnk6m8p3rtmq5h7m56li$_run_closure12#19fbeecd] on root project 'mask-json-field-transform' of type org.gradle.api.Project.

Answer 1

First and foremost, you may not need to 'fix the error' so to speak, in that it appears the problematic code MAY be able to be outright deleted. However...
To fix the error...
Could not find method uploadArchives() for arguments [build_6yphclnk6m8p3rtmq5h7m56li$_run_closure12#19fbeecd] on root project 'mask-json-field-transform' of type org.gradle.api.Project.
This is telling us that uploadArchives is not valid. See immediately below.
I believe you may need to use the maven plugin to access this functionality.
https://github.com/siddeshbg/gradle-uploadArchives/blob/master/README.md
to do this, add:
id 'maven'
to your plugins{}
block.
The above example explains that the maven plugin is responsible for doing this
The Maven plugin adds support for deploying artifacts to Maven repositories
It is worth considering also that the author of the above repository claims:
This is the legacy publishing mechanism, should not be used in newer
builds
Now... on to the better solution, forgetting the maven plugin, in favor of the maven-publish plugin you're already using...
I do not personally work with Maven often enough to know what other mechanisms one should use, but Google suggests that perhaps the maven-publish plugin you're using might do this WITHOUT the 'uploadArchives{}' portion of your code that is causing the error.
See:
https://docs.gradle.org/current/userguide/publishing_maven.html
Per this page, it would seem the entire uploadArchives block is unnecessary
