运行 `mvn endpoints-framework:openApiDocs` 时出现 ClassNotFoundException
ClassNotFoundException when running `mvn endpoints-framework:openApiDocs`
我正处于 GCP openapi guide 的后续步骤，我必须 运行 maven 命令来生成 openapi.json 文件。
我正在关注我自己的项目，所以这可能会或不会通过分叉 example repository 来重现。 （所以我不会，因为我 link 下面是我自己的）
所以当我 运行 他们告诉我的命令时，我得到以下堆栈跟踪，抱怨他们找不到我的 api class，当它非常清楚存在。

编辑：想通了
答案很简单 - mvn endpoints-framework:openApiDocs 只能看到由 mvn package 构建的存储库的最新版本（我假设它在目标或其他东西中）。
所以我更新了我的代码，但从未重新运行 mvn package，所以这就是找不到 class 的原因。
我正处于 GCP openapi guide 的后续步骤，我必须 运行 maven 命令来生成 openapi.json 文件。
我正在关注我自己的项目，所以这可能会或不会通过分叉 example repository 来重现。 （所以我不会，因为我 link 下面是我自己的）
所以当我 运行 他们告诉我的命令时，我得到以下堆栈跟踪，抱怨他们找不到我的 api class，当它非常清楚存在。

编辑：想通了
答案很简单 - mvn endpoints-framework:openApiDocs 只能看到由 mvn package 构建的存储库的最新版本（我假设它在目标或其他东西中）。
所以我更新了我的代码，但从未重新运行 mvn package，所以这就是找不到 class 的原因。
