Failed to execute goal. Could not download npm. Got error code 404 from server

I'm trying to execute the following in my local AEM 6.5.12 instance...

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate -D archetypeGroupId=com.adobe.aem -D archetypeArtifactId=aem-project-archetype -D archetypeVersion=35 -D appTitle="WKND Sites Project" -D appId="wknd" -D groupId="com.adobe.aem.guides" -D artifactId="aem-guides-wknd" -D package="com.adobe.aem.guides.wknd" -D version="0.0.1-SNAPSHOT" -D aemVersion="6.5.12"

...but I keep getting errors, such as the following:

Initially, JAVA HOME was pointing to a JRE folder, but I've since changed it to point to a JDK. Also, there's another discussion where it was suggested to do the following, which worked for several people, but did not work for me:

Change the npm verson of pom.xml in ui folder from 6.4.1 to 3.10.8.

UPDATE: After updating the pom.xml file's npmVersion, I ran Maven again and now get this error:

[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.12.0:npm (npm run prod) on project aem-guides-wknd.ui.frontend: Failed to run task: 'npm run prod' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)
