【问题描述】：

我在部署 Spring Boot 应用程序时遇到问题。
首先我尝试在heroku上部署它，但是出现了错误。
当我尝试在本地部署时出现同样的错误
就是这样：

我猜这是我的 pom 的问题：

我不知道该怎么办。
我将它放在公共存储库中，因此任何敏感数据都不会在那里...
最好的事情是我有几乎相同的应用程序
使用几乎相同的 pom，一切都很好。
我很困惑。

【问题讨论】：

阅读我们收到的错误消息：repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter 所以问题是：你想在哪里部署你的.jar
我应该在哪里部署 jar？我怎样才能实现它？
当你告诉 maven 部署一些东西mvn deploy 你应该指定至少一个 maven 应该用来上传你的工件的存储库。在你的情况下，你没有设置任何东西
但是如果我想将它部署到——例如——heroku，该怎么办？在本地它有效。我放置了分发管理，并在存储库上提供了 url file:target/ 。有用。更糟糕的是在线某处部署程序。我不知道在存储库部分要白色什么

标签： spring-boot maven heroku deployment maven-plugin

【解决方案1】：

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>

我不得不用 java 版本（来自 pom.xml）删除繁荣。
我在我的应用程序的主文件夹中创建了一个 system.properities。
那里我放了java版本，这个：

java.runtime.version=11

比我必须做的简单“mvn deploy”
然后heroku想要我的应用程序。
工作正常。
