This article delves into the common ClassNotFoundException issue in Spring Boot applications, which often arises when using an executable JAR as a dependency due to its internal structure causing class loading failures. By analyzing the repackage mechanism of the Spring Boot Maven Plugin, we explain how the default configuration packages application classes and dependencies into BOOT-INF/classes and BOOT-INF/lib directories, respectively, making it unusable for direct referencing by other projects. The article details the solution of configuring the classifier parameter to generate two separate JAR files: one as a standard Maven artifact and another as an executable JAR. We provide Maven plugin configuration examples for different Spring Boot versions (1.x, 2.x, 3.x) and emphasize the importance of maintaining dependency compatibility in modular development. Additionally, the article discusses the fundamental differences between HTML tags like <br> and characters like \n to help developers better understand formatting in technical documentation.
