I get this pop up every time I run my project. Will this be a problem in the future?
What I did was building up the project with the same name while changing the name of older builds, any ideas?
Pop-up menu
- Windows 10.
- Eclipse 2021-03 (4.19.0)

Answer
Why does Eclipse show multiple application configurations when I try to run my application?
Because you have created all those configurations in your IDE. That’s specific to IDE, and has nothing to do with Java
I get this pop up every time I run my project.
Because IDE doesn’t know which is the configuration you want to use for running your application.
If the question is:
why do they exist?
You may want to run different main methods, in different ways, with different arguments, and so on. That’s why “Run Configurations” exist, to have a pre-configured running setups – you just choose one of them and run your application accordingly.
