Question

我们正在使用spring boot开发spring cloud项目。我们的目标是创建一个可以使用java -jar运行的可执行战争。

我在SO上关注了几个帖子，并且能够通过1）添加“boot”分类器标签来生成可执行文件。 2）在spring-boot-maven-plugin

的执行阶段添加Repackage目标

现在通过这种方法我得到两个war文件：一场不可执行但只能部署的战争和另一个适合我要求的启动分类器的战争

有没有办法只生成可执行的战争？

我正在附加pom.xml以便于参考

Failed to load Main-Class manifest attribute while running java -jar

Answer 1

感谢Stephane建议删除分类器并建议使用starter.io。

我原来的问题是我在目标中获得了两个war文件： 1）Root.war和另一个 2）discovery-service-boot.war

我猜，魔鬼是在maven-war-plugin配置中。我删除了warName和outputDirectory的xml标签后，我得到了可执行文件的战争。

我发布了最终的pom.xml，以帮助面临类似情况的其他人：
