[Solved]-How to achieve that Eclipse clean and build (aka rebuild)?-eclipse

In case you are unable to find a file in Eclipse code after pulling code from git or creating a file in intelliJ seperately (my case) you ca do the following

Right click on 'src' folder and in the menu that appear click on the 'refresh' button

In Eclipse there is an "Auto Build" option, which is checked by default. When it is checked, you don't need to build your project, this happens automatically. If this behaviour is unwanted, uncheck this option and click build project whenever you want.

To clean a project, select Clean Project. This will delete the bin folder, however if Auto build is checked, it will be immediatelly regenerated.
