Eclipse Could not find or load main class [message #1786819]

Hi,

I have installed Eclipse oxygen on my windows 10 laptop. Here are some config info:

Eclipse Version:
Eclipse Java EE IDE for Web Developers.
Version: Oxygen.3a Release (4.7.3a) Build id: 20180405-1200

Java version:
java version "1.8.0_172"
Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)

Windows version: 10 pro

Test code:

public class Test {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("Test");
}
}

I created a java project within Eclipse. Eclipse compiled the code and generated a Test.class file under the bin directory. But "Run as application" doesn't work. The error message is : "Error: Could not find or load main class Test".

Under the bin directory, "java Test" works fine in the command line.

I tried to modify the classpath configurations in Eclipse but with no success.

Is there any place I have missed about Eclipse configuration? Or it is a Eclipse installation issue with Windows?

Thank you in advance for your help.

Wayne

It turned out the Eclipse workspace is under the directory with non ascii characters. Even though within the workspace everything (creating the project, compiling, etc) seemed fine, javaw.exe couldn't reach the bin directory.
So once I moved the workspace outside of the directory, everything works now.
