AssumptionViolatedException这个异常是实现SelfDescribing，但是SelfDescribing来自org.hamcrest.SelfDescribing

3、解决办法
下载hamcrest-core-1.1.jar拷贝到lib目录
或者
在pom.xml添加

<!-- https://mvnrepository.com/artifact/org.hamcrest/hamcrest-core -->
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-core</artifactId>
<version>1.1</version>
</dependency>
