Teamcity prepare release failed due to project name got appended to FETCH URL

I am doing prepare release through Temcity using release-plugin I got below error

[10:46:19][Step 2/3] [INFO] Executing: /bin/sh -c cd

my parent pom have below SCM details

<scm>
    <connection>scm:git:https://testurl.com:8081/scm/myrepo/${env.TEAMCITY_BUILDCONF_NAME}.git</connection>
    <developerConnection>scm:git:https://testurl.com:8081/scm/myrepo/${env.TEAMCITY_BUILDCONF_NAME}.git</developerConnection>
    <tag>1.0.0</tag>
</scm>

I kept my bit-bucket repository name , buildConfName and artifact id same. When i build the parent project it ran successfully , but when I ran tried to build the Child module I see buildConfName got appended automatically to the SCM url configured in Parent POM

Can anyone please tell why extra project name is added?

Thanks

After doing a whole day efforts I found below findings

I am using parent pom in all my other project to just put common properties , common build steps , common dependency version and SCM details as all the project have dotted dependencies and which is not actually maven Modular project. So in child pom maven was appending the artifact id in the scm connection url which is correct behaviour in terms of modular project.
Whereas in git My project is having separate repository for each module and not the subdirectories to parent projects. this results in build failure as repository not found due to wrong url formation.

So I use environment driven properties to be configured for defining the scm connection URL as given below.

changes in the parent pom.xml as below

<profiles>

    <profile>
        <id>parent</id>
         <activation>
          <property>
            <name>scmModule</name>
            <value>parent</value>
          </property>
        </activation>
        <properties>
            <scmConnection>scm:git:https://testurl.com:8081/scm/**myrepo/my-parent.git**</scmConnection>

        </properties>
    </profile>

</profiles> 
<scm>   
    <connection>${scmConnection}</connection>
    <developerConnection>${scmDeveloperConnection}</developerConnection>

While running the build I am using below commands
