Java 如何解决Spring引导程序文件heroku错误

我是heroku的新手，尝试使用github在heroku上部署我的第一个spring boot项目，但我遇到了错误：

at=error code=H14 desc=“没有正在运行的web进程”方法=GET

我做了一些小的研发，并且知道我必须将Procfile添加到github中。因此，在添加ProcFile之后，仍然会出现以下错误：

错误：无法访问JAR文件 target/reactfull-webservice-0.0.1-SNAPSHOT.jar

请任何人都可以建议我应该改变什么

我犯了一个错误

2021-04-07T09:30:17.678838+00:00应用程序[web.1]：错误：无法访问jarfile目标/reactfull-webservice-0.0.1-SNAPSHOT.jar

应该会告诉您出了什么问题。特别是因为您的打包是

war

而不是

jar

。我应该用warweb:java-Dserver.port=$port-jar-target/reactfullwebservice-0.0.1-SNAPSHOT.war替换jar吗？我已经更改了这一点，但仍然得到错误web:java-Dserver.port=$port-jar-target/reactfullwebservice-0.0.1-SNAPSHOT.warweb:java-Dserver.port=$port-war目标/reactfullwebservice-0.0.1-SNAPSHOT.war当我更改此选项时，其显示无法识别的选项：-war我应该更改什么您已将什么更改为什么以及什么错误？添加附加信息作为评论会使其完全不可读，而应编辑您的问题。你为什么把罐子变成了战争。。您只需要更改工件的名称。
