如何在看似正确的“inputSpec”中修复 OpenAPI 错误以生成代码？

Question

我正在尝试运行 OpenAPI 生成器，但我不断收到一条没有意义的错误消息。

Failed to execute goal org.openapitools:openapi-generator-maven-plugin:5.0.0-SNAPSHOT:generate (default-cli) on project miguelmunoz.challenge: The parameters 'inputSpec' for goal org.openapitools:openapi-generator-maven-plugin:5.0.0-SNAPSHOT:generate are missing or invalid

问题是我的inputSpec 值指向一个有效的 .yaml 文件。该文件位于src/main/resources/yaml/pizzeria.yaml，我使用复制和粘贴来确保该路径中没有拼写错误。您可以在https://github.com/SwingGuy1024/OpenAPI_inputSpec_Bug 下载最小可重现测试用例。

这是我的插件规范：

Answer 1

使用maven的编译阶段

mvn clean compile

而不是直接使用插件

mvn openapi-generator:generate

解释：

诀窍是，不要直接调用插件，而是调用“mvn” clean compile"。对 maven 来说有点混乱，但对 我。对不起各位。
