Question

IField field = IType.createField(contents, null, true, null);

How to get the line number of field?

Answer 1

You can get the line number of an ASTNode using the below code

ASTNode node = compilationUnit.findDeclaringNode(field.getKey());

int lineNumber = compilationUnit.getLineNumber(node.getStartPosition()) - 1;

Note that this will work only if the bindings are resolved.
