我的应用程序正在运行，它正在暂存中运行，但在将该构建推送到生产环境后，Heroku正在运行以下命令：

java -Dserver.port=12366 -javaagent:target/newrelic-agent.jar -jar target/newrelic-agent.jar

在重新部署几次之后，它开始使用正确的jar。Heroku是随机选取的吗？

当Heroku检测到您正在使用Spring Boot时，它会自动找出运行应用程序的命令。但是，由于newrelic JAR位于您的目标/目录中，它认为它是您的应用程序

您可以通过两种方式解决此问题：

将newrelic jar放在不同的目录下，如target/dependency或类似目录。创建一个Procfile并显式地告诉Heroku运行应用程序所需的命令。如果创建一个Procfile，它可能如下所示：

然后运行：

git add Procfile
git commit -m "Procfile"
git push heroku master

您可以在中查看默认命令的逻辑。

您的程序文件中有什么？在重新部署几次之后，它开始使用正确的jar。-通常，只有在有新提交的情况下，这才有效。当你做出这些承诺时，你改变了什么？@Chris：没有新的承诺。我没有文件。
