If I follow the steps listed here (https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html) :
mkdir scratch; pushd scratch; mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false; cd my-app; mvn package; mvn clean dependency:copy-dependencies package; mvn site I get several crashes. The first of which is: [INFO] ------------------------------------------------------------- [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] Source option 5 is no longer supported. Use 6 or later. [ERROR] Target option 1.5 is no longer supported. Use 1.6 or later. Even if I fix that error I get another error later.
