I found how to do it:
text.setLabelPlacement(sb.createPointPlacement(0.5, 0.0, 0.0));
It's still another deprecated method (setLabelPlacement), but there is
a way to avoid it :
StyleBuilder sb = new StyleBuilder();
org.geotools.styling.Font[] fontArray = {sb.createFont(new
Font("sansserif", Font.PLAIN, 12))};
TextSymbolizer text = sb.createTextSymbolizer(null,
fontArray,
null,
sb.attributeExpression("depth"),
sb.createPointPlacement(0.5, 0.0, 0.0),
"");
