Assignment to lambda parameter
Reports assignment to, or modification of lambda parameters. Although occasionally intended, this construct may be confusing and is often caused by a typo or use of a wrong variable.
The quick-fix adds a declaration of a new variable.
Example:
list.forEach(s -> {
s = s.trim();
System.out.println("String: " + s);
});
After the quick-fix is applied:
list.forEach(s -> {
String trimmed = s.trim();
System.out.println("String: " + trimmed);
});
