Sakai build error after following installation guide

I have setup my environment for Sakai 19.0 from source following the guide on https://confluence.sakaiproject.org/pages/viewpage.action?pageId=109772882.
However when I try to build the source as detailed in 4.0 of the guide I am getting an error. Below are the logs with debug switched on:

What could I be doing wrong?

On January 15, 2020 the Maven Central repository disabled access through HTTP (cf. Sonatype blog).
While recent version of Maven have the correct URL for Maven Central in their Super POM older ones might still use the HTTP URL. Upgrade your Maven installation or check whether your didn't override the Maven Central repository in your settings.xml file.
The repository configuration should look like this:
<repository>
<id>central</id>
<name>Central Repository</name>
<url>https://repo.maven.apache.org/maven2</url>
<layout>default</layout>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>

Deploying to New Internal Maven Repository

I have a completely empty file system set up as an internal Maven Repository.
I am trying to deploy to this Repository via SFTP.
This is the first jar that I am deploying to the Repository and as I understand it is is possible to point it at a blank writable directory and maven will build up all the correct files.
When running the deploy target I get the following errors:

The gist of the error message is:
File "/public/metcarob/com/BobDiary/BobDiary/0.0.1-SNAPSHOT/maven-metadata.xml" not found.
Of course this file isn't found. It is not in the repository as I am in the process of deploying it. I am expecting this process to create this file.
As this is the first time the jar is being deployed to any repository the file can no possibly exist.
The distribution part of my POM is:
<distributionManagement>
<repository>
<id>ssh-repository</id>
<name>ssh-repository</name>
<url>scpexe://mvn.metcarob.com:71234/public</url>

Are there any settings/methods that I have missed?
(I am running maven via eclipse m2e)
UPDATE:
Some extra information.
In my POM I have

As far as I can see I have followed all the steps from http://maven.apache.org/plugins/maven-deploy-plugin/examples/deploy-ssh-external.html

It is possible to use a simple file system as a maven repository, no need to use a repository manager. I am using a amazon S3 and it works perfectly.
Additionally to the distributionManagement you have to declare a extension in maven, have a look at
deploy-ssh-external
One more thing :
In the stacktrace you are using
scpexe://mvn.metcarob.com:7456
in the pom you use a different port
scpexe://mvn.metcarob.com:71234
This might be a problem, also.

After deleting the existing repository, and rerunning mvn compile. I still get the error.

ommunity?project=Spring%20Web%20Services -> [Help 1]

Looking at The Central Repository
If you do a search for spring-ws you'll see that there is only a pom file available for download for what you precisely specified in your pom.xml.
Looks like you might want to use spring-ws-core like so:
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-ws-core</artifactId>
<version>2.1.4.RELEASE</version>
</dependency>

I don't know if there's a more "regular" way to do this: go to your local maven repository, cd to the directory where that dependency is supposed to be and delete all files (you could even delete the whole org/sprimgframework/ws) then relaunch mvn. It will try to reload all missing dependency.

Look for your settings.xml file which is what maven uses to find your repositories. See what repo it's pointing to and examine that repo to make sure the jars you want exist there.
For example
<profiles>
<profile>
<id>default</id>
<repositories>
<repository>
<id>smss-group-m2</id>
<url>http://repo.mycompany.net/nexus/content/groups/smss-group-m2/</url>
<releases>
<updatePolicy>always</updatePolicy>
</releases>
<repository>
</repository>
</profile>
</profiles>

In the settings.xml file make sure you paste same url of nexus or jfrog repo when you login, whatever url appear on top paste that same
ex:https://artifactory.xxxx/artifactory/webapp/#/home

Jahia6.6 deployment error in maven-built module

I am trying to develop a template-set module for a Jahia site.
I used the step-by-step procedure described in the official documentation available here : http://www.jahia.com/cms/home/download/jahia-academy/documentation.default.html?displayTab=technical-documentation "Templating and Integration Guide".
Basically, it implies to use an maven archetype to initialize, build and deploy your project on the server. The two first steps are correctly done. It generates the module's skeleton and mandatory files. Then, I can build it to create a .war file.
mvn archetype:generate -DarchetypeCatalog=http://maven.jahia.org/maven2
>> [INFO] PROJECT GENERATED
mvn clean install
>> [INFO] BUILD SUCCESS
But an error occurs during the deployment.
mvn jahia:deploy
>> [INFO] BUILD FAILURE
>> [ERROR] Failed to execute goal org.jahia.server:maven-jahia-plugin:2.81:deploy (default-cli) on project test-template-set:
>> Error while validating deployers:Factory not initialized properly,
>> you must set the targetServerDirectory variable before calling getInstance ! -> [Help 1]
>> [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException
The provided link gives me a self explanatory conclusion :
Unlike many other errors, this exception is not generated by the Maven
core itself but by a plugin. The concrete meaning of the exception
depends on the plugin so please have a look at its documentation.
So after using a standard procedure described in the Jahia Documentation, the only piece of advice I could find is to have a closer look at it. Welcome to the catch-22 side of life.
I am using Jahia6.6.1.0 community distribution. I found no further clues in the Jahia fora.
I would like to know which step did I miss. Is this a common maven error ? Or is it just a Jahia mandatory file missing ?
A clue to find a "helloworld working module" would be great as well.
Here is the complete trace of the error :

Maven GAE archetype not working

I'm trying to use google app engine for simple spring based application with maven. I have found that there is maven archetype avaible for that kind of web application (without spring, but this I can add on my own): Maven GAE.
So I used the following command:
mvn archetype:generate -DarchetypeGroupId=net.kindleit -DarchetypeArtifactId=gae-archetype-jsp -DgroupId=com.example -DartifactId=form -DarchetypeRepository=http://maven-gae-plugin.googlecode.com/svn/repository
However, when i tried to use "mvn gae:run" it doesn't work and I don't know how to solve this missing requirement:
