我查了很多遍，没有找到有用的答案。我正在尝试用heroku部署这个api。这是一个预先存在的github存储库，我遵循了heroku的devcenter指南。我尝试通过git和heroku maven插件进行部署，结果是一样的：我可以在本地构建它，一切都很好，但是当我使用cd ~/workspace/API/myapi/ 把它推给希罗库 git push heroku main:main 我得到：

``` `/home/myuser/workspace/API/myapi/.mvn/wrapper/` 包含文件 `maven-wrapper.jar` , `maven-wrapper.properties` 以及 `MavenWrapperDownloader.java` . `/home/myuser/workspace/API/myapi/system.properties` 指定 `java.runtime.version=11` . `/home/myuser/.m2/repository/ar/com/api/myapi/` 包含 `myapi.0.0.1-SNAPSHOT.jar` .
你可以找到 `pom.xml` , `application.properties` ，等等。
我错过了什么？如果你需要更多的信息，请告诉我。提前谢谢！

看起来你有一个
mvnw文件位于项目目录的根目录中，但缺少maven Package 器所需的其他文件。它们通常居住在.mvn/wrapper应用程序的目录。你可能已经删除了它们。您有两种选择：
同时删除maven wrapper的其他文件：
mvnw以及mvnw.cmd重新安装maven wrapper缺少的文件：mvn -N io.takari:maven:0.7.7:wrapper我会选择第二种。通常首选使用 Package 器来确保您的项目以您期望的maven版本运行。
