application.jar中没有主要清单属性

敢说敢作敢为，无怨无恨无悔。这篇文章主要讲述application.jar中没有主要清单属性相关的知识，希望能为你提供帮助。
我在CI环境中的spring boot jar时遇到以下错误

java -jar application.jarno main manifest attribute, in application.jar

奇怪的是，它没有在我的本地或jenkins奴隶问题。它开始没事。
【application.jar中没有主要清单属性】当我将jar上传到Nexus artifactory并在我的CI环境中下载时，它会面临问题。

gradle clean build -x test

我的gradle.build文件

文章咨询没有徒劳1. Gradle- no main manifest attribute 2. http://www.vogella.com/tutorials/Gradle/article.html#specifying-the-java-version-in-your-build-file 3. Can't execute jar- file: "no main manifest attribute"
答案默认打包的jar文件不包含MANIFEST文件。我不知道如何在Gradle中配置，但在Maven中添加插件时：

< plugin> < groupId> org.apache.maven.plugins< /groupId> < artifactId> maven-assembly-plugin< /artifactId> < executions> < execution> < phase> package< /phase> < goals> < goal> single< /goal> < /goals> < /execution> < /executions> < configuration> < archive> < manifest> < addClasspath> true< /addClasspath> < mainClass> vn.dung.Application< /mainClass> < /manifest> < /archive> < descriptorRefs> < descriptorRef> jar-with-dependencies< /descriptorRef> < /descriptorRefs> < appendAssemblyId> false< /appendAssemblyId> < /configuration> < /plugin>

它对我有用。您可以将Maven插件配置更改为Gradle。
另一答案我必须在构建jar后运行gradle bootRepackage并git我可以执行的jar！
另一答案在build.gradle中，我注意到启动重新打包已禁用，因此我启用了它：
