How to build and run Maven projects after importing into Eclipse IDE

I would recommend you don't use the m2eclipse command line tools (i.e. mvn eclipse:eclipse) and instead use the built-in Maven support, known as m2e.

Delete your project from Eclipse, then run mvn eclipse:clean on your project to remove the m2eclipse project data. Finally, with a modern version of Eclipse, just do "Import > Maven > Existing project into workspace..." and select your pom.xml.

M2e will automatically manage your dependencies and download them as required. It also supports Maven builds through a new "Run as Maven build..." interface. It's rather nifty.

1.Update project

Right Click on your project maven > update project

2.Build project

Right Click on your project again. run as > Maven build

If you have not created a “Run configuration” yet, it will open a new configuration with some auto filled values.

You can change the name. "Base directory" will be a auto filled value for you. Keep it as it is. Give maven command to ”Goals” fields.

i.e, “clean install” for building purpose

Click apply

Click run.

3.Run project on tomcat

Right Click on your project again. run as > Run-Configuration. It will open Run-Configuration window for you.

Right Click on “Maven Build” from the right side column and Select “New”. It will open a blank configuration for you.

Change the name as you want. For the base directory field you can choose values using 3 buttons(workspace,FileSystem,Variables). You can also copy and paste the auto generated value from previously created Run-configuration. Give the Goals as “tomcat:run”. Click apply. Click run.
