./main.sh: line 6: $input_file: ambiguous redirect

这个错误提示是在运行一个脚本时出现的，它告诉你在第6行有一个指令没有正确的重定向输入文件。这可能是因为在代码中输入文件的路径没有正确设置，或者是由于输入文件的路径不正确。一种可能性是使用输入时没有加上引号，导致脚本无法正确读取文件名。你可以检查脚本中的输入文件路径是否正确，或者查看输入文件是否存在，这些可能有助于解决问题。

这是一个 Spring Boot 应用程序的错误，错误信息显示了一个依赖注入的问题。具体来说，Spring Boot 在初始化 `documentationPluginsBootstrapper` bean 时遇到了问题，因为它需要满足一个构造函数参数的依赖项，但是该依赖项无法满足。更具体地说，该依赖项是 `webMvcRequestHandlerProvider` bean，它本身也有一个构造函数参数的依赖项，即 `requestMappingHandlerMapping` bean。但是，在初始化 `requestMappingHandlerMapping` bean 时，它遇到了一个歧义映射的问题，因此无法正确初始化。解决这个问题需要进一步检查应用程序的配置和依赖项，以找到并解决这个歧义映射的问题。

这个错误是因为在Spring的Web MVC配置中，有一个方法（com.example.spring.controller.Others.SendEmail）被映射到了多个URL上，导致无法确定应该映射到哪个URL。这种情况被称为“模糊映射（Ambiguous mapping）”。需要修改映射关系，确保每个方法只被映射到单一的URL上。
