在尝试制作一个我可以干净独立地启动的独立 JAR 时，我遇到了涉及 Jersey 和我理想的胖 JAR 的问题。最后一个 jar 将被移动到 Docker 映像。
我得到的错误基本上是这样的：
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.glassfish.jersey.server.ResourceConfig]: Factory method 'jerseyResourceConfig' threw exception; nested exception is org.glassfish.jersey.server.internal.scanning.ResourceFinderException: java.io.FileNotFoundException: /dir/myproject-1.0.0-SNAPSHOT.jar!/BOOT-INF/classes (No such file or directory)

这是我在POM文件中的构建配置文件：

最后，以下是我正在使用的所有球衣依赖项：

我已经通读了从这个SO问题中引用的所有来源。我被引导经历了一些 github 问题，Spring 和 Jersey 显然都已经修复了这些问题，但我仍在处理这些并发症。 我的复杂性的独特之处在于，找不到的引导/类直接在我的 jar 中并引用项目本身。它不是抱怨一个不同的，依赖于jar，它抱怨项目自己的/BOOT-INF/类。
上述SO问题中未提及的任何其他见解都将非常有用！我发现Java在Docker中的使用比我经历过的任何其他堆栈(python-django和node-js(都要困难得多。如果需要更多信息，请告诉我。
尝试添加以下插件
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
</plugin>
