I created new Java module from scratch in my project. "create 'src' folder" was selected in module creation wizard. There is single "com" package in source folder which contains two public classes (say A and B). A class instantiates B class. IDE does not show errors and B class source is opened on "ctrl+B" pressing when cursor is located on the class name inside A class source. But when I'm trying to compile A class (by context menu -> "compile A.java class") following error is shown
Error:(15, 20) cannot find symbol class B
"src" folder is marked as source root.
It looks like IDE bug.
Someone suggested to do "File->Invalidate Caches" to fix alike issue also asked on SO. I tried that and it did not help.
What possible reason of that and how it can be fixed?

In the above program, "Cannot find symbol" error will occur because “sum” is not declared. In order to solve the error, we need to define “int sum = n1+n2” before using the variable sum.
The cannot find symbol error, also found under the names of symbol not found and cannot resolve symbol , is a Java compile-time error which emerges whenever there is an identifier in the source code which the compiler is unable to work out what it refers to.
Create a project, then create a Java module. Put your class there and execute it. If you only want/need the IDE for editing the Java file, edit the file accordingly, then compile it using javac and execute the class using java WhateverTheNameOfYourClass .
Try compiling the whole project (or at least class B) first.
If you compile only class A, class B cannot be found because it hasn't been compiled yet (therefore, no bytecode B.class file exists).
This is not intuitive, but true. IDEA doesn't automatically compile dependant classes when you compile single class.
