Please read the documentation of the valid style flags for the
constructor Button (Composite parent, int style) - SWT.NONE is not a
valid one for org.eclipse.swt.widgets.Button.

@Override
public void createPartControl(Composite parent) {
Composite composite = new Composite(parent, SWT.NONE);
composite.setLayout(new GridLayout());

final Label label = new Label(composite, SWT.BORDER);
label.setText("Select the File::");

Button button = new Button(composite, SWT.BORDER);
button.setText("Change Label Text");

button.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
label.setText("New Updated Text");
super.widgetSelected(e);
}
});
}

Thanks and Regards
Karthikeyan
