Please cross check system requirements as well as build section here https://github.com/adobe/aem-guides-wknd and make sure your system has correct java and maven versions.

I don't see a problem. I tried to build the latest main branch of the wknd project with MacOSX, with no security features enabled with the Java and Maven versions below:

➜  aem-guides-wknd-main java -version
java version "11.0.21" 2023-10-17 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.21+9-LTS-193)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.21+9-LTS-193, mixed mode)

➜  aem-guides-wknd-main mvn -version
Apache Maven 3.9.6 (bc0240f3c744dd6b6ec2920b3cd08dcc295161ae)
Maven home: /opt/homebrew/Cellar/maven/3.9.6/libexec
Java version: 11.0.21, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home
Default locale: en_CA, platform encoding: UTF-8
OS name: "mac os x", version: "14.1.2", arch: "aarch64", family: "mac"

It might be a Maven issue, where your version is wrong. After I downloaded the zip from https://github.com/adobe/aem-guides-wknd, I unzipped, cd into that folder structure, and mvn clean install. Works...
