Configure Maven scm plugin to use serverID from settings.xml

Question

I have a settings.xml file with some servers set:

<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">

 ...
  <servers>

    <server>
      <id>server1</id>
      <username>user1</username>
      <!-- encrypted like https://maven.apache.org/guides/mini/guide-encryption.html  -->
      <password>{xxxxx}</password>
    </server>

    <server>
      <id>server2</id>
      <username>user2</username>
      <!-- encrypted like https://maven.apache.org/guides/mini/guide-encryption.html  -->
      <password>{xxxxx}</password>
    </server>

    <server>
      <id>svn</id>
      <username>userSVN</username>
      <!-- encrypted like https://maven.apache.org/guides/mini/guide-encryption.html  -->
      <password>{xxxxx}</password>
    </server>

  </servers>
...

I read here that it is not possible to set a specific server to the scm plugin, and that you have to add a property to your pom.xml

  <project>
   ...
    <properties>
      <project.scm.id>my-scm-server<project.scm.id>
    </properties>
  </project>

Here is my pom.xml

I try to run a mvn versions:update-parent and my build fail with

svn: E170001: Authentication required for 'https://xxx:443 Subversion Repository 'xxx' '

Here is the Maven command:

/bin/apache-maven-3.2.5/bin/mvn clean versions:update-parent -DallowSnapshots=true validate -Pcommit-pom -B -U --settings ../settings-maven/null_settings.xml --global-settings ../settings-maven/full-settings.xml

I tried with a non-encrypted password and it doesn't work too...

Thanks for your help!

The answer was on this page

In the settings.xml via a server entry, using the host name from the connection URL as the server id

If my SVN server URL is "https://myserver.com" the id of the server in the settings.xml has to be "myserver.com"
