我以前使用maven生成过jar文件，却从未遇到过我当前项目遇到的这个奇怪问题。
这是一个春季项目，其中包含以下pom.xml：
<?xml version="1.0" encoding="UTF-8"?>

我正在使用以下命令进行构建：
mvn clean compile package
其中仅包含一些其他依赖项，而没有src/main/java下的实际代码。
请忽略pom.xml的jar-with-dependencies部分，我不希望将依赖关系打包在我的jar中。我不确定我在这里缺少什么，您能指出吗？
此外，我检查了项目的构建路径，可以看到src / main / java被识别为源文件夹，并且在pom.xml的<sourceDirectory/>标记中也明确提到了它。
