Convert directories with java files to java modules in intellij

If you get the directory from some version system and it has a maven pom.xml configuration file, here’s a solution:

• Find the pom.xml in the directory.

• Right click the pom.xml.

• Then you can see the popup windows. Select the last item "add as maven project file".

• Then, the maven build tool can automatically discern the directory as an module and import the specified jar dependencies.
