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 时出现以下错误：-

[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.

[ERROR] Failed to execute goal com.google.cloud.tools:appengine-maven-plugin:2.2.0:deploy (default-cli) on project demo: App Engine application deployment failed: com.google.cloud.tools.appengine.operations.clo

我搜索了很多地方，发现Version Error when building Web App。但未能得出解决方案。如果可能，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。这个插件的配置标签会指向插件的version参数。

虽然文档中没有提到它，但错误很清楚地说明了那个点“。”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，所以可能就可以删除它了。

希望对你有帮助！

更新：

在这种特殊情况下，删除标签 <deploy.version> 并不成功。但是，它使用值1。感谢@AyushSurana 的更新！
