Affects PMD Version:
7.2.0
Rule:
MissingStaticMethodInNonInstantiatableClass
https://docs.pmd-code.org/latest/pmd_rules_java_errorprone.html#missingstaticmethodinnoninstantiatableclass
Description:
Under certain circumstances, classes are identified as non-instantiatable, and then trigger the rule, even though the class can in fact be instantiated.
Code Sample demonstrating the issue:
public class MyClass {
private MyClass() {
}
public static class Builder {
private Builder() {
}
public static Builder builder() {
return new Builder();
}
public MyClass build() {
return new MyClass();
}
}
}
Expected outcome:
PMD reports a violation at line 1, but that's wrong. That's a false positive. The class can be instantiated with Builder.builder().build().
