java - 我们可以将 kamon 用于 Java 应用程序指标吗？

Question

我的 java 测试代码给出了 Kamon 导入错误“找不到符号 Kamon”我在我的 maven 配置中添加了 kamon 的依赖项。请告诉我哪里出错了？我的示例代码：

package com.logicbig.example;
import kamon;
import kamon.prometheus.PrometheusReporter;

import java.io.IOException;

public class SampleClass {
    static void main(String args[]) throws IOException {
        Kamon.addReporter(new PrometheusReporter());
    }

}
