Can't compile XMLBean generated classes with Maven due to 'ñ"

I am working on a project and I can't compile that generates XMLBeans from a WSDL.

The files are generated ok, but when I want to compile the project, I have problems with a few classes.

The main problem, I guess, is that the name of the class has an ñ, AñoDocument.java and it doesn't compile.

In Eclipse -> Project -> Properties -> Resource -> Text Encoding I have checked "Inherit from container (Cp1252)".

Does any one have any idea about how can I do to fix this?

I don't think the problem is with the ñ character itself. This is a perfectly valid character for a class name, as demonstrated by the following test class (which I know prints true on JDK 1.6).

public class Main {
    public static void main(String[] args) {
         System.out.println(Character.isJavaIdentifierPart('ñ'));
    }
}

You are saving the file in Cp1252, which is compatible with UTF-8 for ASCII characters, but not for non-ASCII. Then you tell maven that your source files are encoded in UTF-8. This causes maven to read the ñ character incorrectly, which appears in your build when it interprets ñ as the character \65533 - the replacement character. Try to change the Resource encoding to UTF-8 under Eclipse -> Project -> Properties -> Resource -> Text Encoding

From the Java Language Spec:

The Java letters include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in mechanically generated source code or, rarely, to access preexisting names on legacy systems.

In other words, it's illegal to have an n-tilde on a class name. Which means that many tools are likely to be unhappy with it in a Java filename as well.

Update See comments below. Looks like this is completely wrong. Would delete it, but the comments are worthwhile.

I solved in this way: 1) close eclipse, 2) mvn clean, 3) mvn compile
