Question

我有一个使用Ivy / Ant的Wiremock项目用于依赖/构建。当我从Eclipse中的启动文件运行它时，它成功启动服务器并请求成功。但是，当我将其构建为docker镜像并运行它时，它会立即崩溃。

docker build：

docker build --force-rm -t <REPO_LOCATION>/assignment_form_api_mock:latest -t <REPO_LOCATION>/assignment_form_api_mock:1.0.6 .

docker run：

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"

加载扩展名docker时会记录此堆栈跟踪：

当我在谷歌上搜索时，我看到人们对杰克逊有版本问题：https://github.com/tomakehurst/wiremock/issues/282

因此我使用wiremock-standalone。我也尝试隐式覆盖杰克逊版本，以确保使用相同版本的jackson-annotations，jackson-databind和jackson-core。如果我没有隐式添加依赖项，我会得到相同的错误，但引入的jar是版本：

jackson-annotations-2.1.2.jar
jackson-core-2.1.3.jar
jackson-databind-2.1.3.jar

Ivy Dependencies：

<dependencies>
    <dependency org="com.github.tomakehurst" name="wiremock-standalone" rev="2.7.1" conf="compile->default"/>
    <dependency org="io.rest-assured" name="rest-assured" rev="3.0.3" conf="test->default"/>
    <dependency org="com.gatesbiz.common" name="logback_core" rev="2.0.13" conf="compile->compile;test->test"/>
    <dependency org="commons-io" name="commons-io" rev="2.5"/>
    <dependency org="com.fasterxml.jackson.core" name="jackson-annotations" rev="2.9.0"/>
    <dependency org="com.fasterxml.jackson.core" name="jackson-databind" rev="2.9.0"/>
    <dependency org="com.fasterxml.jackson.core" name="jackson-core" rev="2.9.0"/>
</dependencies>

Dockerfile：

FROM rodolpheche/wiremock
ADD src/test/resources /home/wiremock 
ADD /bin /var/wiremock/extensions/af-extensions.jar

搬运工-compose.yml

在Docker容器中部署Wiremock时出现NoClassDefFoundError
