当地一切都很好,我成功地把它推给了heroku。Git输出:
remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> JVM Common app detected
remote: -----> Installing OpenJDK 1.8... done
remote: -----> Discovering process types
remote: Procfile declares types -> web
remote:
remote: -----> Compressing...
remote: Done: 49.1M

remote: Verifying deploy... done.
但是heroku日志告诉我:
Error: Unable to access jarfile target/dependency/webapp-runner.jar
我尝试清理并运行Procfile中的确切命令,在本地机器上一切都很顺利。那么这里有什么问题呢?运行此命令以更改构建包:
$ heroku buildpacks:set heroku/java
然后再推一次git
现在,您的应用程序正在使用JVM构建包,它不运行Maven。当您尝试heroku deploy:war或heroku Maven插件时,可能会遇到这种情况。我偶然发现了这个问题。这是我的pom.xml构建目标

因此,可以在运行war文件时找到webrunner 结果,我的问题是我的.gitignore文件中有
target
文件夹
我知道这很愚蠢,但对于任何绝望的人,仔细检查一下,这不是你的问题
