使用java.jar以tools.jar作为依赖项运行spring boot

Question

我正在尝试运行一个需要tools.jar作为依赖项的springboot应用程序，我运行“mvn package spring-boot：run”并且一切正常，但是在使用“mvn package spring-boot：repackage”打包并运行java之后-jar生成的boot.jar抛出以下错误

java -jar "site-0.1.0-spring-boot.jar" 
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/attach/AttachNotSupportedException

任何想法如何在没有mvn的情况下运行它？ 我做得怎么样？

Answer 1

系统范围依赖关系不会添加到重新打包的jar中（例如'fat'jar）。 这就是为什么你的应用程序在开发中工作正常（使用“本地”类路径），而不是作为单独的包启动时。

即将发布的Spring Boot 1.4.0.RC1版本将支持此功能 ：您将能够在Maven插件配置中设置includeSystemScope ，并且将包含任何系统范围的依赖项。 请注意，重新包装tools.jar可能是一种气味，请参阅此问题
