问题描述
我在部署Spring Boot应用程序时遇到问题。
首先，我尝试将其部署在heroku上，但是出现错误。
当我尝试在本地部署它时，出现了相同的错误
就是这样：

我想这是我pom的问题：

我不知道该怎么办。
我将其放在公共存储库中，所以任何敏感数据都不会在那里...
最好的是，我有几乎相同的应用程序
几乎都是相同的pom，一切都很好。
我很困惑。
解决方法
终于我解决了这个问题。
首先，我必须在pom.xml中建立一个存储库
<distributionManagement>
<repository>
<id>myrepository</id>
<url>file:.mvn/maven-repo</url>
</repository>
</distributionManagement>
比我不得不删除Java版本（从pom.xml中删除）的繁荣。
我已经在应用程序的主文件夹中创建了一个system.properities。
在那里我放了java版本，
java.runtime.version=11
比我只需要简单地'mvn deploy'
然后heroku想要我的应用。
效果很好。
