由于 MongoMetricsConnectionPoolListener 冲突，如何解决 karate-core 无法与 spring boot 2.5.0 一起工作的问题

Question

我有一个 spring 引导项目，它使用我正在使用空手道测试的执行器。我最近尝试将我的项目从使用 spring boot 2.4.5 更新到 2.5.0。由于进行了更改，我的测试现在失败并出现以下错误：

    An attempt was made to call a method that does not exist. The attempt was made from the following location:

    Action:
    
    Correct the classpath of your application so that it contains a single, compatible version of io.micrometer.core.instrument.binder.mongodb.MongoMetricsConnectionPoolListener

查看 karate-core-1.0 的内容。1.jar 它有这些千分尺的副本类在 jar 本身内有阴影，而不是将它们作为依赖项拉出，这意味着有我无法在我的 gradle 文件中排除这种依赖关系。我还可以看到这些类在这里被故意加了阴影：https://github.com/intuit/karate/blob/master/karate-core/pom.xml#L203.

Spring boot 2.4.5 actuator 正在使用micrometer-core版本：1.6.6 Spring boot 2.5.0 actuator 正在使用 micrometer-core 版本：1.7.0

所以我预计问题是这两个版本之间的重大变化导致了这个问题。为了让 karate-core 与 spring-boot 2.5.0 完美搭配，我需要一个与 micrometer-core 1.7.0 兼容的 karate-core 版本。我看不到 karate-core 本身对千分尺的任何直接依赖，所以我猜它可能是传递性地拉动它？

我也试图排除致动器引入的千分尺核心依赖性，但这会破坏致动器的功能，导致：

是否有计划创建可与 spring boot 2.5.0 一起使用的 karate-core 版本？或者有人对我如何解决这个问题有任何其他建议吗？

Answer 1

是的，我们当然从未预料到这一点。我们可能不得不考虑为团队发布一个单独的“非阴影”工件。

欢迎提出问题，我们会进行调查。当然，如果你能做出贡献，那就更好了。

你暂时可以试试这个，让我知道进展如何。我认为您应该能够在本地创建自己的 JAR 并使用 maven-shade 从 karate fat-jar 中移除千分尺。然后在您的项目中使用该依赖项。我想不出别的了。
