io/opentracing/util/GlobalTracer调用阿里云内容检测api-jar包问题，还包含后续异常Tracer，noop

问题来源

使用maven 转 web项目将pom依赖换成jar包，随后出现的jar包问题。

1. 问题1 NoClassDefFoundError: io/opentracing/util/GlobalTracer

Exception in thread "main" java.lang.NoClassDefFoundError: io/opentracing/util/GlobalTracer

	at java.net.URLClassLoader.findClass(URLClassLoader.java:354)

2. 问题2 问题1解决后的异常 ClassNotFoundException: io.opentracing.Tracer
3. 问题3 问题1&2 解决后出现noop的异常，开不开心。

解决方法

自己搜了下，然后被逼无奈写个笔记

1. 添加新jar包，笔者用的0.33.0一套的jar包
2. ** opentracing-util 、 opentracing-api 、 opentracing-noop **这三个搜
3. jar全部列表
4. jar包链接: https://mvnrepository.com/artifact/io.opentracing/opentracing-noop/0.33.0.
