cannot be resolved to a type! [message #1798429] Sun, 18 November 2018 14:17 Go to next message
Eclipse UserFriend
Hey guys!

I hope I posted this topic under the right headline and if not I apologize. I am new when it comes to Eclipse and I have to do a lab in Java before I start studying this fall. But for some reason I constantly get the message "cannot be resolved to a type" when I try to create my type in the main project. I have googled constantly and tried every possible solution out there but nothing works. I have the Eclipse IDE for EE Developers because we are supposed to use that one and the JAVA-10 because I have Windows 10.

I really hope you can help me!

The message "X cannot be resolved to a type" can have many reasons (involving simple/qualified names, imports, project dependencies and more).
Without seeing your project it's impossible to guess which reason applies in your case.
For an experiment you could try to explain to us, why you believe JDT should be able to resolve the given type.

Since you said you were new to Eclipse, try these:

* Single out the type on which you are getting the error.
* What do you know about this type? Is this is a source type in your project that you or your team created? Or is this a binary type your project needs.
* If this is a source file, you should be able to locate the .java file within your workspace. Else, the corresponding class file should be found either in an exploded directory or inside any of the jar files in your project or workspace. If you can't find it, you should bring it into your workspace/project and eventually to the buildpath.
