Maven 将实际 jar 生成为 .jar.original 而不是 .jar 文件 [英] Maven generating actual jar as .jar.original instead of .jar file
问题描述
基本上我有一个 Maven 项目，我正在尝试使用 mvn clean compile package 通过 spring 工具套件使用下面的 pom.xml 生成我的项目的 jar.
Basically I have a Maven Project and I am trying to generate a jar of my project using mvn clean compile package through spring tool suite using below pom.xml.
命令执行后，我在我的 target 文件夹中生成了 2 个 jar 文件 - {project-name}.jar &{project-name}.jar.original
After the command is executed, I get 2 jar files generated in my target folder - {project-name}.jar & {project-name}.jar.original
.jar 文件包含Spring boot 框架类文件具有此contents 而 .jar.original 文件包含我的应用程序的实际类文件.
The .jar file contains
Spring boot framework class files having this contents while the .jar.original file contains actual class files of my application.
我也尝试过使用 mvn clean install 但没有成功.而且，只安装了 1 个对我来说没用的文件，因为它不包含我的应用程序的任何 class 文件，但包含 spring 框架类.
I also tried using mvn clean install but no luck with it. Moreover, the only 1 file is installed which is useless for me, because it does not contain any class files of my application but contains spring framework classes.

推荐答案
spring-boot-maven 插件默认使用 repackage 目标，它打包 pom 文件中提到的所有依赖项.发生这种情况时，您项目的类和资源 jar 将重命名为原始".
spring-boot-maven plugin by default uses the repackage goal which packages all dependencies mentioned in the pom file. When this happens, your project's classes and resources jar is renamed to "original".
