# Building Kyuubi ## Building Kyuubi with Apache Maven **Kyuubi** is built based on [Apache Maven](http://maven.apache.org), ```bash ./build/mvn clean package -DskipTests ``` This results in the creation of all sub-modules of Kyuubi project without running any unit test. If you want to test it manually, you can start Kyuubi directly from the Kyuubi project root by running ```bash bin/kyuubi start ``` ## Building a Submodule Individually For instance, you can build the Kyuubi Common module using: ```bash build/mvn clean package -pl :kyuubi-common -DskipTests ``` ## Building Submodules Individually For instance, you can build the Kyuubi Common module using: ```bash build/mvn clean package -pl :kyuubi-common,:kyuubi-ha -DskipTests ``` ## Skipping Some modules For instance, you can build the Kyuubi modules without Kyuubi Codecov and Assembly modules using: ```bash mvn clean install -pl '!:kyuubi-codecov,!:kyuubi-assembly' -DskipTests ``` ## Building Kyuubi against Different Apache Spark versions Since v1.1.0, Kyuubi support building with different Spark profiles, Profile | Default | Since --- | --- | --- -Pspark-3.0 | Yes | 1.0.0 -Pspark-3.1 | No | 1.1.0 ## Defining the Apache Mirror for Spark By default, we use `https://archive.apache.org/dist/spark/` to download the built-in Spark release package, but if you find it hard to reach, or the downloading speed is too slow, you can define the `spark.archive.mirror` property to a suitable Apache mirror site. For instance, ```bash build/mvn clean package -Dspark.archive.mirror=https://mirrors.bfsu.edu.cn/apache/spark/spark-3.0.1 ``` Visit [Apache Mirrors](http://www.apache.org/mirrors/) and choose a mirror based on your region. Specifically for developers in China mainland, you can use the pre-defined profile named `mirror-cn` which use `mirrors.bfsu.edu.cn` to speed up Spark Binary downloading. For instance, ```bash build/mvn clean package -Pmirror-cn ```
