无法使用Swagger-Codegen-Maven-Plugin生成代码

问题描述 投票：0回答：1

我尝试在 SpringBoot 项目中使用 Swagger Swagger-Codegen-Maven-Plugin 从 yaml 文件生成 java 代码，但它不起作用。 我已经配置了 swagger-codegen-plugin 并创建了一个 yaml 文件，但是当我尝试编译/生成时，我遇到了相同的错误。 我正在添加我的 pom.xml、yaml 文件和错误日志 如果有人能帮助我，我会很高兴！

该问题已在插件的更高版本中修复。例如，它适用于

        <groupId>io.swagger.codegen.v3</groupId>
        <artifactId>swagger-codegen-maven-plugin</artifactId>
        <version>3.0.35</version>

和

java 17
。
