App Engine 部署失败：进程处理程序异常 - 非零退出 [2]

Question

我正在尝试在 Google App Engine 上部署 Spring Boot Java 11 项目。

在运行 mvn appengine:deploy 上出现以下错误：-

[INFO] GCLOUD: ERROR: (gcloud.app.deploy) argument --version/-v: Bad value [1.0]: May only contain lowercase letters, digits, and hyphens. Must begin and end with a letter or digit. Must not exceed 63 characters.

我找遍了各个地方，找到了Version Error when building Web App。但未能达成解决方案。如果可能的话请帮帮我。

谢谢。

Answer 1

我查看了此 document，据我了解，这与 <deploy.version>1.0</deploy.version> 有关。此插件配置标签引用插件的 version 参数。

虽然文档中没有提及，但错误非常清楚地指出点“.”不是版本值的有效字符。只允许使用连字符。

文档说如果你不指定这个参数，它会自动生成，所以也许它足以删除它。

希望对您有所帮助！

更新：

在这种特殊情况下，删除标签 <deploy.version> 不成功。但是它对值 1 有效。感谢@AyushSurana 的更新！
