SonarQube Java分析器是否应该能够检测“重复局部变量”错误？

在Eclipse中创建follow Java类，它会说有一个重复的局部变量错误

public class Test {

    public static void main(String[] args) {
        hello();
    }

    private static void hello() {
        int a=1;
        int a=1;
    }
}

然后用SonarQube分析这个Java类，可以毫无问题地分析它，难道不应该报告语义问题吗

在本例中，分析时没有抛出任何错误。您使用的编译器是什么？我希望类似的东西会出现编译器错误。我在类上使用Sonar，所以在我的例子中，构建失败，Sonar根本不运行。在我的例子中，我们只分析Java源代码，而不是二进制代码。这是完全相同的例子，如果代码不能像您的例子那样编译，sonarqube Java analyzer在语义分析上会失败。如果你只分析来源，你可能会得到更准确的结果。此外，正如@Vlasec所指出的，这与分析一开始不可编译/编译的代码似乎不相关这一事实无关。
