无法为使用 maven-shaded-plugin 创建的 jar 获取条目 BOOT-INF/lib 的嵌套存档

Question

我正在使用 spring-boot-maven-plugin:2.1.0.RELEASE 来打包我的主线应用程序。此应用程序已打包所有常见的依赖项等

在一个单独的项目中，我正在使用 maven-shade-plugin:2.4.3 构建一个阴影 jar，并使用 org.codehaus.mojo:truezip-maven-plugin 在 BOOT-INF/lib 目录下注入我的 Spring Boot 应用程序：1.1。现在，当我启动我的 spring-boot 应用程序时，我遇到了以下异常；

我试图复制 BOOT-INF/lib 中的 jar，直接取出 maven-truezip-plugin，但还是一样。无论如何我可以解决这个问题吗？或解决方法？

Answer 1

在构建 jar 时将其添加到插件配置中。

           <archiverConfig>
                <compress>false</compress>
            </archiverConfig>

Answer 2

为我们修复，同样的失败消息，是只使用 spring-boot-maven-plugin（它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。

Answer 3

可以解决问题，在我的 maven 包构建中；

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 现在有以下附加步骤；

pom.xml

        <execution>

            </goals>
            <configuration>

                    <property name="sourceArtifact" value="${project.build.directory}/SPRING-BOOT-app.jar" />
                    <property name="appendWith" value="${project.build.directory}/${project.artifactId}-${project.version}.jar" /> 
                    <ant antfile="${packager.utilities.directory}/build.xml"> 
                        <target name="append-and-repack-spring-boot-artiafact" />

注意：请勿使用 7Zip/Winrar 或任何其他压缩工具打开您计划部署的 Spring Boot 应用程序。它会更新压缩偏移（或其他东西）并且应用程序会失败。只是不要触摸人工制品，复制并检查！
