I am new to Linux. I have used Eclipse Oxygen with WindowBuilder 1.9.0 to build GUI applications.

My current setup is CentOS 7.6, WindowBuilder 1.9.2 JDK 11.0.3

Tried to make a simple Gui App and it gives me error.

Description Resource Path Location Type
EventQueue cannot be resolved GuiTrial1.java /guiTrial1/src/guiTrial1 line 15 Java Problem
JFrame cannot be resolved to a type GuiTrial1.java /guiTrial1/src/guiTrial1 line 9 Java Problem
JFrame cannot be resolved to a type GuiTrial1.java /guiTrial1/src/guiTrial1 line 19 Java Problem

The type java.awt.EventQueue is not accessible GuiTrial1.java /guiTrial1/src/guiTrial1 line 3 Java Problem
The type javax.swing.JFrame is not accessible GuiTrial1.java /guiTrial1/src/guiTrial1 line 5 Java Problem

I appreciate any help in getting my problem resolved. I have always liked WindowBuilder and do not know if there is another GUI builder like it.

Java 11 uses the module system. Did you create a module-info.java file for your Eclipse project? Swing and AWT classes are in the java.desktop module.

Oh. Look at that. I saved the module-info.java and it fixed the errors..
My Bad. Looks like sometimes you need to save stuff and sometimes not.
I'm new to this.

in April 2020 using Eclipse Version: 2020-03 (4.15.0)
and JavaSE-13, I'm getting the following:

just changed the module-info.java to contain:

module guiExample {
	
	requires java.desktop;
}

and still have these errors:

Description	Resource	Path	Location	Type
BorderLayout cannot be resolved to a type	MyCalc.java	/GuiExample/src/com/windyweather	line 38	Java Problem
EmptyBorder cannot be resolved to a type	MyCalc.java	/GuiExample/src/com/windyweather	line 37	Java Problem
EventQueue cannot be resolved	MyCalc.java	/GuiExample/src/com/windyweather	line 18	Java Problem

JPanel cannot be resolved to a type	MyCalc.java	/GuiExample/src/com/windyweather	line 12	Java Problem
[...]
