Problem with enums when building an AST [message #1106621]

Hi

When obtaining a compilation unit from the following basic enum:

public enum Day {
SUNDAY, MONDAY, TUESDAY, WEDNESDAY,
THURSDAY, FRIDAY, SATURDAY;
}

The compilation unit doesn't contain anything and I get the following messages, from within the compilation unit.

Messages:

Syntax error on token "enum", interface expected
Syntax error on token ",", delete this token

I got this problem before and updated all my libraries to the most current being shipped with Eclipse Kepler, but the problem remains.

Any help, would be appreciated.

Thanks

How exactly do you obtain the AST?
You must tell JDT which Java source version it should parse.
Apparently, it tried to parse it as Java 1.4 or less.

Hi

This is how I obtain the Compilation unit

public static CompilationUnit GetCU(String path) {
	ASTParser parser = ASTParser.newParser(AST.JLS4);

	String f = null;
	f = readFile(path);
	parser.setSource(f.toCharArray());

	parser.setKind(ASTParser.K_COMPILATION_UNIT);
	return (CompilationUnit) parser.createAST(null);
}

Thanks

Fixed it with:

public static CompilationUnit GetCU(String path) {
		ASTParser parser = ASTParser.newParser(AST.JLS4);

		String f = readFile(path);
		parser.setSource(f.toCharArray());

		Map options = JavaCore.getOptions();
		JavaCore.setComplianceOptions(JavaCore.VERSION_1_7, options);
		parser.setCompilerOptions(options);
		return (CompilationUnit) parser.createAST(null);
}
