Affects PMD Version:
6.13.0
Rule:
UnnecessaryLocalBeforeReturn
Description:
An unnecessary local is missed if chained method calls are split up on separate lines AND the method calls reference another variable.
Code Sample demonstrating the issue:
public class Test {
public Object test1() {
int i = 0; // the usage of i seems to be relevant for the false negative
Object o = thing()
.make(i);
return o; // false negative when the chained calls are on separate lines
}
public Object test2() {
int i = 0;
Object o = thing().make(i);
return o; // true positive
}
public Object test3() {
Object o = thing()
.make();
return o; // true positive
}
public Object test4() {
Object o = thing().make();
return o; // true positive
}
}
