我正在使用spring-boot-maven-plugin：2.1.0.RELEASE打包我的主线应用程序。此应用程序已打包了所有常见的依赖项
在一个单独的项目中，我正在使用maven-shade-plugin：2.4.3构建一个有阴影的jar，并使用org.codehaus.mojo：truezip-maven-plugin注入到BOOT-INF / lib目录下的spring boot应用程序中：1.1。现在，当我启动spring-boot应用程序时，我会遇到以下异常；

我试图直接将maven-truezip-plugin复制出来，复制到BOOT-INF / lib内的jar，但还是一样。反正有什么我可以解决的？或解决方法？

好，在我的maven软件包中解决此问题；
1) Invoked ANT to unzip the released template SPRING-BOOT-app.jar
2) Unzip and repackage additional shaded artefact from the project
3) Copy repackaged artefact under BOOT-INF/lib
4) Repackage SPRING-BOOT-app.jar
我的pom现在需要执行以下附加步骤；
pom.xml

注意：请勿使用7Zip / Winrar或任何其他压缩工具打开您打算部署的Spring Boot App。它将更新压缩偏移量（或其他值），并且应用程序将失败。只是不要触摸文物，复制并检查！
答案 1 :(得分：0)
为我们解决的错误消息是，仅使用spring-boot-maven-plugin（为您创建一个可运行的jar），而不是使用shade插件并从该jar运行它。

在构建 jar 时将其添加到插件配置中。
<archiverConfig>
<compress>false</compress>
</archiverConfig>
