Atlas-release workaround needed

Hello everyone,
i´ve developed a small Space blueprint for internal use. Now I´m trying to get a jar or obr “release” of this Blueprint.
When running atlas-release I get this exception:

[ERROR] Failed to execute goal com.atlassian.maven.plugins:maven-amps-dispatcher-plugin:6.2.11:release (default-cli) on project customerbp: Unable to execute mojo: java.lang.reflect.InvocationTargetException: NullPointerException ->[Help 1]

After googleing for the error code i founde this:
https://ecosystem.atlassian.net/browse/AMPS-1107

So it seems this a bug in the Atlassian SDK. I didn´t quiet understand if it was resolved or how but on the amps version 6.2.11 I still get it.

So now my question: Is there a workaround for this?
I´ve read something that I should use maven directly instead of the altas-release command. But as my java skill are pretty low i´m not sure how to do this.

Will apreciate any help !

Thank you and beste regards
Irakli Edjibia

-------------------EDIT--------------
found this: Tutorial on atlas-release missing?
It says to use:
mvn:reprare and mvn:perfom
it also shows a example scm tag, in this tag they reference Bitbucket
To build a release of my blueprint I probably have to reference our own git with the repository of my blueprint project instead of the Bitbucket repository?

Yes. For scm you should use your own git.
You can read tons of documentation for that, but usually the order goes like

mvn release:prepare -DdryRun=true
mvn release:prepare
release:perform -DreleaseVersion=thereleaseversion -DdevelopmentVersion=thenewdevversion

Read an example of what is going on here

Hi Panos,
first of all thanks for your answer but I still cant get it to work. :-/

mvn release:prepare -Ddryrun=true
and
mvn release:prepare
fninshes fine without any problems! And prompts me a BUILD SUCCESS
but running mvn release:perform prompts me the following error:

The goal you specified requires a project to execute but there is no POM in this directory

After googling this error though I´ve found a workaround there:

So I tried
mvn release:perform -Dgoals='deploy -f parent_project_folder/pom.xml'
this time maven downloaded some stuff and worked quited longer then without -Dgoals but still failed with the same error message >_<

[Error] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project customerbp->SNAPSHOT: Deployment feiled: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::lyout::url parameter ->[Help1 ]

Thank you!
