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

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

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，我已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 下载最低限度的可重现测试用例。

这是我的插件规范：

                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

解决方法

使用maven的编译阶段

mvn clean compile

而不是直接使用插件

mvn openapi-generator:generate

说明：

诀窍是，不要直接调用插件，而是调用“mvn 干净的编译”。关于 maven 有点但令人困惑，但可以 我。对不起各位。
