Most wanted Maven commands

... which I used to forget!

• Build project quickly: don't check if there are updated artifacts (i.e., offline mode) and don't run tests
  

  cd [project root dir]
  mvn clean install -o -DskipTests

• Run main() method of your java class
  

  mvn exec:java -Dexec.mainClass="com.example.Main" [-Dexec.args="argument1"]

• Build a project module and all modules it depends on
  

  cd [project root dir]
  mvn clean install -pl [relative path from current dir to module you want to build] -am

• Continue to build a project from the module on which previous build procedure has been interrupted (for example, because of build failure)
  

  cd [project root dir]
  mvn clean install -rf [relative path from current dir to module on which previous build procedure has been interrupted]

• Get the project dependency tree
  

  mvn dependency:tree

• Run specific goal for a given plugin
  

  mvn [plugin groupId]:[plugin artifactId]:[specific goal]

• Initialize new project in maven way
  

  mvn archetype:generate

• Generate Eclipse project file(s) for your (built with Maven) project
  

  cd [project root dir]
  mvn eclipse:clean eclipse:eclipse
