How to configure Maven to use HTTPS when connecting to repo.maven.apache.org

Question

I would like to secure the connection to repo.maven.apache.org when resolving dependencies (I wolud like to secure all connections made by Maven actually), but I'm not used to Maven configuration... My user settings.xml contains the following repositories and pluginRepositories sections:

<profiles>
    <profile>
        <id>main</id>
        <repositories>
            <repository>
                <id>central</id>
                <url>https://repo.maven.apache.org</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
            </repository>
        </repositories>

        <pluginRepositories>
            <pluginRepository>
                <id>central</id>
                <url>https://repo.maven.apache.org</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
            </pluginRepository>
        </pluginRepositories>
    </profile>
</profiles>

However Maven is unable to resolve dependencies with that setup.

Answer 1

Open the file $MAVEN_HOME/conf/settings.xml (where $MAVEN_HOME is the folder in which Maven has been installed) in a text editor. Then, add the following to the <mirrors>...</mirrors> section in this file:

<mirror>
  <id>central-secure</id>
  <url>https://repo.maven.apache.org/maven2</url>
  <mirrorOf>central</mirrorOf>
</mirror>
