 Camel K uses https://maven.apache.org[Apache Maven] to build the integration kits and its related containers. The Apache Maven settings for Camel K are stored in a ConfigMap `camel-k-maven-settings` in the {tutorial-namespace} namespace. One of the ways to make the build faster is by using a maven repository manager such as https://www.sonatype.com/nexus-repository-oss[Sonatype Nexus], the repository manager helps in caching the maven artifacts from remote repositories and serves them from local the subsequent times they are asked to be downloaded.
