-Maven and Gradle do not use the system proxy settings. If the target software component (repository)
-is using either of these build tools, make sure to set up the following environment variables:
-
-.. code-block:: shell

-  export MAVEN_OPTS="-Dhttp.proxyHost=wwww-example-proxy -Dhttp.proxyPort=80 -Dhttps.proxyHost=wwww-example-proxy -Dhttps.proxyPort=80"

-In addition, Macaron uses the global settings files for Maven and Gradle if present on the host machine and copies them to
-the Docker container. You can set up your proxy settings in the following files:
-
-* ``~/.m2/settings.xml``
-* ``~/.gradle/gradle.properties``

-See the `Maven <https://maven.apache.org/settings.html#proxies>`_ and `Gradle <https://docs.gradle.org/current/userguide/build_environment.html#sec:accessing_the_web_via_a_proxy>`_ documentations for more information on setting up proxies.
