您好,我需要知道如何通过 mavan 安装一次构建 war 和 jar 文件
我需要使用战争文件在谷歌应用程序引擎上部署,并使用 jar 文件通过命令在 jenkin 上执行(java -jar ...
这是pom.xml文件

这个pom.xml可以创建战争和jar文件,但是如果我尝试通过这个命令java -jar执行jar文件...它显示错误
Exception in thread "main" java.lang.NoClassDefFoundError: org.springframework/boot/SpringApplication
问题是Spring Boot的Maven插件不参与jar的创建,因此它没有被执行。
当 Spring 引导重新打包战争文件时,它将被设置为可执行。这意味着,与其尝试同时构建罐子和战争,不如使用 java -jar
运行战争。
@andywilkenson的答案绝对是我的首选方法,但无论如何,这是如何做到的:D
您需要确定哪个可交付成果是"主要"工件。我建议使用 jar,因为使用 war 文件作为依赖项是没有意义的(使用 SpringBoot 可执行 jar 作为依赖项也没有意义)。
步骤
- 使包装值等于主工件("jar")的包装类型。
- 添加具有标准配置的 spring-boot-maven-plugin。
- 为 maven war 和 jar 插件添加显式声明。
- 为每个插件创建执行配置,否则只会运行与项目打包匹配的插件。只需将配置放置在该插件的执行中。
- 将"分类器"添加到辅助项目。这很重要,所以我们知道哪个是主要的,哪个是次要的工件(如"源"罐)。

Do not declare an execution for jar, since it is the main artifact.
Doing so makes maven think you are trying to add another
