realm = plugin> codehaus.mojo：sonar-maven-plugin：3.7.0.1746

Question

我根据github sonar-custom-rules-examples/java-custom-rules/上的说明编写了Java自定义扫描规则。我的Java自定义规则已成功添加到SonarQube，但是在扫描Code Engineering Times时发生以下错误。谁能帮助我获得以下错误的解决方案。

欢迎提供解决问题的任何提示！

谢谢！

Answer 1

尽管不清楚为什么会发生这种情况，但我以另一种方式规避了此错误。这就是之前编写的代码：

JavaSymbol.VariableJavaSymbol variableJavaSymbol = (JavaSymbol.VariableJavaSymbol) identifierTree.symbol();
VariableTree variableTree = variableJavaSymbol.declaration();

为了避免错误，未使用JavaSymbol.VariableJavaSymbol。

VariableTree variableTree = (VariableTree) identifierTree.symbol().declaration();
