java - checkstyle 自定义检查错误 无法实例化 com.mycompany.checks.MethodLimitCheck

Question

我正在尝试使用基于https://checkstyle.org/writingchecks.html的 checkstyle-8.38-all.jar 进行基本的自定义检查。有人有这个自定义检查的工作示例吗？我将 mycompany-checkstyle-checks-1.0.jar 和 checkstyle-8.38-all.jar 添加到 java 类路径中仍然没有运气。

我不断收到此错误

java -classpath mycompany-checkstyle-checks-1.0.jar;checkstyle-8.38-all.jar com.puppycrawl.tools.checkstyle.Main -c checkstyle.xml src/
