Maven

1. build from submodule

You dont need to build from the head of project.

./mvnw clean package -DskipTests  -rf :<$submodule-name>

you can find the <$submodule-name> from submodule ’s pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

	<modelVersion>4.0.0</modelVersion>

	<parent>
		<groupId>org.apache.flink</groupId>
		<artifactId>flink-formats</artifactId>
		<version>1.20-SNAPSHOT</version>
	</parent>

	<artifactId>flink-avro</artifactId>
	<name>Flink : Formats : Avro</name>

Then you can modify the command as

./mvnw clean package -DskipTests  -rf :flink-avro

The result will look like this

Normally, build Flink will start from module flink-parent

2. skip some other test

For example, you can skip RAT test by doing this:

./mvnw clean package -DskipTests '-Drat.skip=true'
