我也遇到过同样的问题，只是解决了它。

最初，我使用maven-assembly-plugin生成fat jar，它创建了一个名为mavenproject1-0.0.1-snapshot-jar-with-dependencies.jar的文件。当我尝试运行它时，这个文件给出了与您提到的相同的问题。

我认为，因为它是一个Spring Boot应用程序，所以您需要使用他们的插件。我将包装更改为spring-boot-maven-plugin，它生成了两个文件:mavenproject1-0.0.1-snapshot.jar和mavenproject1-0.0.1-snapshot.jar.origine。只需尝试java-jar target/mavenproject1-0.0.1-snapshot.jar，它希望能够工作。：-）

我对Spring和Spring Boot相当陌生，并被要求从事一个遗留的Spring Boot项目。我应该在项目中包括Spring Boot提供的一些FailureAnalyzer。根据我遇到的教程（比如这里），所需要做的就是在meta-inf/spring.factors文件中注册几个FailureAnalyzer类。但是当我构建项目时（使用Maven），在target/meta-inf目录中

我正在使用 Maven 来构建一个 Java 项目，我有几个文件，和，我想将它们复制到 JAR 文件内的目录中。到目前为止，我的工作如下: 但这也会在编译时将这两个文件复制到目录中。所以我希望这些文件包含在JAR文件中，而不是其他地方。有办法做到这一点吗？
