Heroku上的Java Spring MVC错误：无法访问jarfile target/dependency/webapp-runner.jar

我使用Heroku部署带有PostgreSQL数据库的Spring MVC java应用程序。数据库链接工作正常，PostgreSQL初始化成功

部署成功，没有错误或奇怪的警告消息，但现在应用程序失败

以下是日志：

    heroku[web.1]: State changed from crashed to starting
    heroku[web.1]: Starting process with command `java $JAVA_OPTS -Dspring.profiles.active="datajpa,heroku" -DMISIC_ROOT="." -jar target/dependency/webapp-runner.jar --port 28363 target/*.war`
    heroku[web.1]: State changed from starting to crashed
    heroku[web.1]: Process exited with status 1
    app[web.1]: Setting JAVA_TOOL_OPTIONS defaults based on dyno size. Custom settings will override them.
    app[web.1]: Error: Unable to access jarfile target/dependency/webapp-runner.jar
    heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=misic.herokuapp.com request_id=a242ee89-5594-4f48-9d14-432d46b17600 fwd="178.21.66.110" dyno= connect= service= status=503 bytes= protocol=https

我没有找到关于stackoverflow的任何答案，这将解决我的问题。 为什么Heroku找不到webapp-runner.jar，我不知道！ 在localhost上，一切工作都很完美

My pom.xml（部分）

链接到Github：

我解决了这个问题。出于某种原因，Heroku不使用文件setings.xml。当我将此文件的内容传输到pom.xml并将其删除时，一切正常。

请确保您的

pom.xml中有类似的内容：

org.apache.maven.plugins
当我试图通过git而不是jarfile来部署jhipster upp时，我遇到了这个问题。我之所以拥有它，是因为Node.js buildpack是在java的buildpack之前启动的，所以我被迫用
heroku:buildpacks add--index 2 heroku/nodejs
和heroku:buildpacks add--index 1 heroku/java`来设置它们，但即使在这一更改之后，我仍然有相同的错误。2） 然后我意识到我在pom、xml中使用了jar打包，而不是必需的war打包。将此值更改为pom.xml对我有帮助
 请查看我的答案，以便找到您的Procfile。这是我的配置
