How do you configure Maven default settings for an idea?

To set up Maven’s default configuration, you can follow the steps below:

1. Open the installation directory of Maven and locate the settings.xml file in the conf folder.
2. Open the settings.xml file and locate the section.
3. Within the node, multiple nodes can be added, with each node representing a configuration.
4. Within the node, you can configure a series of options, such as indicating the unique identifier of the configuration, indicating the repositories used, and indicating the plugin repositories used.
5. At the end of the node, you can add an node to specify the default activated configuration.
6. Within the node, multiple nodes can be added, with each node representing a default active configuration.
7. Save the settings.xml file.
8. Now Maven will build using the default configuration you have set.

Here is an example of a settings.xml file, with a default configuration named my-profile.

<settings>
  <profiles>
    <profile>
      <id>my-profile</id>
      <repositories>
        <repository>
          <id>central</id>
          <url>https://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
    </profile>
  </profiles>
  <activeProfiles>
    <activeProfile>my-profile</activeProfile>
  </activeProfiles>
</settings>

In the example above, the my-profile configuration uses the default central repository (Maven Central Repository) and disables the download of snapshot versions.
