在Docker容器中部署Wiremock时发生NoClassDefFoundError
我有一个使用Ivy / Ant进行依赖关系/构build的Wiremock项目。 当我从Eclipse中的启动文件运行它时，它成功启动服务器，请求成功。 但是，当我将其构build为Docker镜像并运行它时，它立即崩溃。
dockerbuild设：
docker build --force-rm -t <REPO_LOCATION>/assignment_form_api_mock:latest -t <REPO_LOCATION>/assignment_form_api_mock:1.0.6 . docker运行：
docker run -d --name form-api-mock -p 10404:8080 <REPO_LOCATION>/assignment_form_api_mock --verbose --extensions="com.gatesbiz.assignmentdispatch.mock.RequestTemplateTransformerGlobal,com.gatesbiz.assignmentdispatch.mock.AdminAreasRequestTransformer,com.gatesbiz.assignmentdispatch.mock.FormsRequestTransformer,com.gatesbiz.assignmentdispatch.mock.VehicleRequestTransformer"
在加载扩展docker时logging这个堆栈跟踪：

当我search时，我发现人们遇到了jackson的版本问题： https ： //github.com/tomakehurst/wiremock/issues/282
出于这个原因，我正在使用电线独立。 我也试着隐含覆盖杰克森版本，以确保使用相同版本的jackson注释，jackson数据绑定和jackson核心。 如果我不隐式添加依赖关系，则会得到相同的错误，但是带入的jar文件是以下版本：
jackson-annotations-2.1.2.jar jackson-core-2.1.3.jar jackson-databind-2.1.3.jar
