Spring boot 部署spring引导应用程序时出现问题

部署Spring boot应用程序时遇到问题。
首先，我试图在heroku上部署它，但出现了一个错误。
当我试图在本地部署它时，出现了相同的错误
就是这样：

我想这是我的pom的一个问题：

我不知道该怎么办。
我将其放在公共存储库中，因此任何敏感数据都不可能存在…
最好的是，我有几乎相同的应用程序
基本上都是相同的pom，一切都很好。

---

我很困惑。
我终于解决了这个问题。
首先，我必须在pom.xml中创建一个存储库

    <distributionManagement>
    <repository>
        <id>myrepository</id>
        <url>file:.mvn/maven-repo</url>
    </repository>
</distributionManagement>

而我只需要简单地进行“mvn部署”
然后heroku想要我的应用程序

---

工作正常。

阅读我们收到的错误消息：

存储库元素未在POM-inside-distributionManagement元素或-DaltDeploymentRepository=id:：layout:：url参数中指定

，因此问题是：您想在哪里部署

.jar

我应该在哪里部署jar？如何指定？当您告诉maven部署某个

mvn deploy

时，您应该指定至少一个存储库，maven应该使用该存储库上载您的工件。在你的例子中，你没有设置任何东西，但是如果我想在heroku上部署它，该怎么办？在本地，它是有效的。我将distributionmanagement放在存储库中，并在存储库中给出url文件：target/。它起作用了。更糟糕的是将程序部署到在线的某个地方。在那里，我不知道在存储库部分中要删除什么

java.runtime.version=11
