java - 尝试从 mvn clean 安装但与 eclipse JunitTest 一起正常工作时，wiremock 抛出 Nullpointer

Question

我正在使用以下wiremock依赖项:

com.github.tomakehurst独立的wiremock测试2.6.0

当通过选择 Run as JunitTest 从 Eclipse 运行时，一切工作正常。但是当我从 Maven 运行这个程序时，我收到以下错误。

wiremock.com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: com.github.tomakehurst.wiremock.stubbing.StubMapping["request"]->com.github.tomakehurst.wiremock.matching.RequestPattern["bodyPatterns"]->java.util.ArrayList[0])

Caused by: java.lang.NullPointerException
at com.example.integration.controller.FileUploadControllerIntegrationTest.configureSystemUnderTest(FileUploadControllerIntegrationTest.java:47)

我有以下代码，该代码抛出错误。

这是我正在使用的映射文件有效负载。

2.6.0 已经很古老了。

尝试 2.25.1，并使用 jre8 JAR，除非您使用的是 Java 7。
