1) run mvn package alone

2) create pom.xml

"the simplest pom"

<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>

<groupId>org.pierre.maventests</groupId>

<artifactId>firsttest</artifactId>

<packaging>jar</packaging>

<properties>

<maven.compiler.source>1.8</maven.compiler.source>

<maven.compiler.target>1.8</maven.compiler.target>

</properties>

</project>

3) create from archetype

mvn archetype:generate -DgroupId=org.pierre.maventests -DartifactId=firsttest -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

or simply

mvn archetype:generate

cd firsttest
