sonar custom rule check java collection type is unknownSymbol












0














Collection type always return 'unknownSymbol' in a custom sonar check rule class.



//demo class



public class SaasConstantNameCheckCase {
private static final long serialVersionUID;
private final String title;
public static final Integer maxSize = 1111;// Noncompliant
private static List list = new ArrayList<>();
private static HashMap<String, String> map = new HashMap<>();
}


// custom rule class



@Override
public void visitVariable(VariableTree tree) {
VariableSymbol symbol = (VariableSymbol) tree.symbol();
String type = symbol.type().name();
System.out.println("type->"+type);
}


// test result



type->long
type->String
type->Integer
type->!unknownSymbol!
type->!unknownSymbol!


Why?

    Is your sample source code complete? This looks to me like a type resolution issue, and I don't see the "import" statements for List or HashMap.

  • No need for self-bashing, I think it's an honest mistake :) If you don't mind, I'll post an answer to document this issue - IMHO it is quite common.

SonarJava will show this unknownSymbol! string when it fails to resolve the actual type symbols.



In this particular case, you should either use fully qualified types java.util.List and java.util.HashMap, or import them.
