[FIXED] How can I stop Maven from automatically updating its local repository?

Issue

I'm developing a Java-based application and using Maven to manage its packages with Visual Studio Code.

While coding, I have noticed that my git detects some slf4j files were automatically updated even though I did nothing about my code. The updated files are not actually libraries, but only Javadoc, sources, and some text files.

I don't want them to update automatically but want to manually update them if needed. What is the cause of this behavior and how can I suppress it?

I know I can stop Maven from updating dependent libraries when building my codes by attaching -o to a command, is there any similar ways?

Solution

I've modified the configuration file settings.xml to include the following section and now Maven no longer updates its local repository.

<profiles>
  <profile>
    <repositories>
      <repository>
        <id>repo1</id>
        <url>https://repo.maven.apache.org/maven2/</url>
        <releases>
          <updatePolicy>Never</updatePolicy>
        </releases>
        <snapshots>
          <updatePolicy>Never</updatePolicy>
        </snapshots>
      </repository>
    </repositories>
  </profile>
</profiles>

repository section is needed for all repos that are currently used. Even with this setting, Maven can download libraries if they don't exist in the local repository when building a package.
