java - 部署到 Google App Engine

coder 2024-03-07 原文

我正在为 Google App Engine 苦苦挣扎。我想要做的就是:

从 https://cloud.google.com/appengine/docs/java/tools/maven 部署留言簿应用程序(我选择了留言簿应用程序)
设置推送部署 https://cloud.google.com/tools/repo/push-to-deploy

我正在按照教程的确切步骤进行操作。我已经试过好几次了。该应用程序在 Jenkins 中构建良好(我设法使其运行)但部署失败。

+ gcloud --project=MyProject preview app deploy target/guestbook-1.0-SNAPSHOT.war
ERROR: File [/var/jenkins/workspace/MyProject/target/guestbook-1.0-SNAPSHOT.war] is not a valid deployable item.
ERROR: (gcloud.preview.app.deploy) Errors occurred while parsing the App Engine app configuration: 
Build step 'Execute shell' marked build as failure
Finished: FAILURE

在本地开发网络服务器上一切正常。 MyProject 是项目 ID(我只是为示例更改了它)。我究竟做错了什么。我的意思是我忘记做某事了吗？我从事 Java 已经五年多了，我不明白为什么做这么基础的事情会这么难。请帮助我

我做错了什么，我错过了什么吗？我完全按照他们说的去做了。

我尝试使用 Google Source 作为存储库和 Github。什么都不管用。

最佳答案

部署失败，因为您的 jenkins 构建脚本失败了:

构建步骤“Execute shell”将构建标记为失败

在“执行 shell”步骤中，您必须确保脚本以状态 0 返回。任何其他情况都被视为失败。 See this SO answer to a similar issue .

看来您的“执行 shell”部分是这个:

[MyGuestbook] $ /bin/sh -xe /tmp/hudson5523568617447680772.sh
+ gcloud --project=MyProject preview app deploy target/myapp-1.0-SNAPSHOT.war
ERROR: File [/var/jenkins/workspace/MyGuestbook/target/myapp-1.0-SNAPSHOT.war] is not a valid deployable item.
ERROR: (gcloud.preview.app.deploy) Errors occurred while parsing the App Engine app configuration: 
Build step 'Execute shell' marked build as failure
Finished: FAILURE

构建的“执行 shell”部分失败，因为从脚本返回的状态代码似乎是从 gcloud 命令返回的状态代码。如果您查看文档 here, you can see that it doesn't accept .war archives, but only unpacked war folders .您可以简单地从

更改行

gcloud --project=MyProject preview app deploy target/myapp-1.0-SNAPSHOT.war

到

gcloud --project=MyProject preview app deploy target/myapp-1.0-SNAPSHOT

此时，构建的“执行 shell”部分将正常运行，因此整个 jenkins 构建应该正确完成。

渐变

如果您使用 gradle 进行构建，它可能已经生成了一个分解的应用程序目录:

build/exploded-app
