问题
Everytime I try to create a new java project Eclipse keeps asking if I want to add a module-info java file to the source folder. It's getting pretty annoying as there's no immediately obvious option to opt out of this check.
IDE for Java Developers, Photon release 4.8.0

See while creating a new project, after you click>> next on the very first dialog "new java project." There is one another dialog box pops up when you click >> finish. It will lead you to the 3rd dialog box which asks for the creation of module-info java file?? & gives you two option create & don't create. You should select "don't create."
Here are some advantages of the file module-info.java contents: To declare a jar file as a named module, one needs to provide a module-info.class file, which is, naturally, compiled from a module-info.java file. It declares the dependencies within the module system and allows the compiler and the runtime to police the boundaries/access violations between the modules in your application. Let’s look at the file syntax and the keywords you can use.
- Module module.name – declares a module called module.name.
- Requires module.name – specifies that our module depends on the module module.name, allows this module to access public types exported in the target module.
- Requires transitive module.name – any modules that depend on this module automatically depend on module.name.
- Exports pkg.name says that our module exports public members in package pkg.name for every module requiring this one.
- Exports pkg.name to module.name the same as above, but limits which modules can use the public members from the package pkg.name.
- Uses class.name makes the current module a consumer for service class.name.
- Provides class.name with class.name.impl registers class.name.impl class a service that provides an implementation of the class.name service. opens pkg.name allows other modules to use reflection to access the private members of package pkg.name.
- Opens pkg.name to module.name does the same, but limits which modules can have reflection access to the private members in the pkg.name.
One great thing about the module-info.java syntax is that the modern IDEs would fully support your efforts of writing them. Perhaps all of them would work beautifully. I know that IntelliJ IDEA does content assist, quick fixes of the module files when you import classes from the module you haven’t required yet, and so on. I don’t doubt Eclipse IDE and NetBeans IDE offer the same.
