java -/BOOT-INF/classes (No such file or directory) on spring boot java project

Question

在尝试制作一个独立的 JAR 以便我可以干净、独立地启动时，我遇到了涉及 Jersey 和我想要的胖 JAR 的问题。最终的 jar 将被移动到 Docker 镜像。

我得到的错误本质上是这样的:

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)

这是我的 POM 文件中的构建配置文件:

<profile>
    <id>d2</id>
    <activation>
        <activeByDefault>false</activeByDefault>
    </activation>
    <properties>
        <packaging.type>jar</packaging.type>
        <log.dir>logs</log.dir>
        <!-- updates bootstrap.properties -->
        <config.override.path>./conf</config.override.path>
    </properties>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <requiresUnpack>
                        <dependency>
                            <groupId>my.com</groupId>
                            <artifactId>myArtifact</artifactId>
                        </dependency>
                    </requiresUnpack>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</profile>

最后，这是我正在使用的所有 jersey 依赖项:

org.springframework.boot:spring-boot-starter-jersey:jar:1.5.12.RELEASE:compile
|  |  +- org.glassfish.jersey.core:jersey-server:jar:2.25.1:compile
|  |  |  +- org.glassfish.jersey.core:jersey-client:jar:2.25.1:compile

|     |  \- org.glassfish.jersey.core:jersey-common:jar:2.25.1:compile
|     |     +- org.glassfish.jersey.bundles.repackaged:jersey-guava:jar:2.25.1:compile
|     \- org.glassfish.jersey.media:jersey-media-multipart:jar:2.25.1:compile

我已通读此 SO question 中引用的所有来源.我被引导解决了一些 Spring 和 Jersey 显然已经修复的 github 问题，但我仍在处理这些并发症。我的并发症的独特之处在于，未找到的 boot-inf/classes 直接在我的 jar 中并引用项目本身。它不是提示不同的依赖 jar，而是提示项目自己的/BOOT-INF/classes。

上述 SO 问题中未提及的任何其他见解都将非常有用!我发现在 Docker 中使用 Java 比我体验过的任何其他堆栈(python-django 和 node-js)都难得多。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>
