Smack's pom.xml has already the required section under distributionManagement:

  <distributionManagement>
   ...
   <repository>
     <id>github</id>
     <name>GitHub Apache Maven Packages</name>
     <url>https://maven.pkg.github.com/smacklib/dev_smack</url>
   </repository>
   ...
  </distributionManagement>

In addition make sure that you configured repository access as described on the Consuming Smack page. The difference is that you need a PAT with upload credentials.

<settings>
    ...
        <servers>
            <server>
                <id>github</id>
                <username>michab66</username>
                <password>313...PAT</password>
                </server>
	</servers>
</settings>

A problem on Windows is that the default path to $JAVA_HOME does contain spaces. A solution is to create a directory c:\links and place junctions to the respective Java installations there. The command to use is mklink. See the example below:

mklink c:\links\jdk11 /J "c:\Program Files\Amazon Coretto\jdk11.0.7_10"
set JAVA_HOME=c:\links\jdk11 -- Define this in the system environment variables.
PATH=%JAVA_HOME%\bin -- Define in user environment variables.

Note that for switching jdks PATH as well as JAVA_HOME need to be updated.
