How would one know which Java IDE created a Java project by looking at the files and folders?
Do most IDEs create the same project files such that any IDE (Eclipse, Intellij IDEA, NetBeans, etc) can open and execute without modification?
I have a project I’ve inherited and just want to figure out which tool it was created with. Nothing more.
If you want to work independently from IDEs, use Maven. Most IDEs allow you to import Maven projects (after installing the necessary plugin), which will generate the correct project files for that IDE. Mostly such files shouldn’t be added to source control, so use svn/git ignore on them.
If it has an .settings folder, it’s eclipse, if it have a .idea folder, it’s InteiJ Idea. But that doesn’t matter, because you don’t need them. Just create an empty java project in your favorite IDE (or use Maven as above) and drop the source code in it
