IntelliJ - Convert a Java project module into a Maven project module

Question

I have a project on Bitbucket  Only the sources are committed  To retrieve the project onto a new machine  I used Version Control   Checkout from Version Control from within IntelliJ   It then asks whether I would like to create a new project from this source  to which I reply Yes  So far  so good  It creates a nice little Java project for me  consisting of a single module   However  my goal in pulling this project into IntelliJ was to turn it into a Maven project  I cannot find any option anywhere that will let me do this   Is there a way to have IntelliJ just generate a basic empty pom xml for me  with a name and an artifactId and a repository  Or  is there a way to import the project as a Maven project in the first place   Whenever I try to create a project from existing source  it only gives me the option of a Java project

Right-click on the module  select  Add framework support      and check the  Maven  technology    This also creates a pom xml for you to modify    If you mean adding source repository elements  I think you need to do that manually ndash not sure   Pre-IntelliJ 13 this won t convert the project to the Maven Standard Directory Layout  13  it will

I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project  This is due the fact that Intellij Idea  2017  takes some important settings only from the pom xml then which can lead to some confusion  following sections are affected at least    Annotation settings are changed for the modules Compiler output path is changed for the modules Resources settings are ignored totally and only taken from pom xml Module dependencies are messed up and have to checked Language Encoding settings are changed for the modules   All these points need review and adjusting but after this it works like charm   Further more unfortunately there is no sufficient pom xml template created  I have added an example which might help to solve most problems    lt 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 xsd maven-4 0 0 xsd  gt   lt modelVersion gt 4 0 0 lt  modelVersion gt   lt groupId gt Name lt  groupId gt   lt artifactId gt Artifact lt  artifactId gt   lt version gt 4 0 lt  version gt   lt properties gt       lt  -- Generic properties -- gt       lt java version gt 1 8 lt  java version gt       lt project build sourceEncoding gt UTF-8 lt  project build sourceEncoding gt       lt project reporting outputEncoding gt UTF-8 lt  project reporting outputEncoding gt   lt  properties gt   lt dependencies gt       lt  --All dependencies to put here  including module dependencies-- gt   lt  dependencies gt   lt build gt       lt directory gt   project basedir  target lt  directory gt       lt outputDirectory gt   project build directory  classes lt  outputDirectory gt       lt testOutputDirectory gt   project build directory  test-classes lt  testOutputDirectory gt       lt sourceDirectory gt   project basedir  src main java lt  sourceDirectory gt       lt testSourceDirectory gt    project basedir  src test java lt  testSourceDirectory gt        lt resources gt           lt resource gt               lt directory gt   project basedir  src main java lt  directory gt               lt excludes gt                   lt exclude gt      java lt  exclude gt               lt  excludes gt           lt  resource gt           lt resource gt               lt directory gt   project basedir  src main resources lt  directory gt               lt includes gt                   lt include gt      lt  include gt               lt  includes gt           lt  resource gt       lt  resources gt       lt plugins gt           lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-compiler-plugin lt  artifactId gt               lt version gt 3 5 1 lt  version gt               lt configuration gt                   lt annotationProcessors  gt                   lt source gt   java version  lt  source gt                   lt target gt   java version  lt  target gt               lt  configuration gt           lt  plugin gt       lt  plugins gt   lt  build gt      Edit 2019     Added recursive resource scan Added directory specification which might be important to avoid confusion of IDEA recarding the content root structure

I had a different scenario  but still landed on this answer  I had imported my root project folder containing multiple Maven projects but also some other stuff used in this project  IntelliJ recognised the Java files  but didn t resolve the Maven dependencies   I fixed this by performing a right-click on each pom and then  Add as maven project
