How do I open a Java project (that uses maven) in Eclipse? (Do I use M2E or maven-eclipse-plugin)

Question

I'm trying to open this project in Eclipse but not sure how.

I followed the build instructions and not sure how I tell Eclipse to use Maven as the source control (if required) and then open the Java project so I can step through it.

I discovered that there are two Maven plugins for Eclipse (M2E and maven-eclipse-plugin) and not sure which one to choose, since they are incompatible with each other and I need to use.

Answer 1

From the OS command line, in the directory of the pom.xml file:

mvn eclipse:clean eclipse:eclipse

This will create the various eclipse project files. Then in eclipse, in the "Project" pane, right-click > "Import existing project" and navigate to the directory - you'll find it has recognised there's now a project to import.

Answer 2

This should work:

Right click in the Package Explorer, choose Import.

From the context-menu of the Package Explorer choose import.

In the now open panel search for Existing Maven projects. The rest is pretty much self explaining.
