Heroku 上的 Java Spring MVC 错误：无法访问 jarfile 目标/依赖项/

Question

我使用 Heroku 将我的 Spring MVC java 应用程序与 PostgreSQL 数据库一起部署。链接到数据库工作正常，PostgreSQL 已成功初始化。

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

我没有在stackoverflow上找到任何答案，这可以解决我的问题。为什么 Heroku 找不到 webapp-runner.jar，我不知道！在本地主机上一切正常。

我的 pom.xml（部分）

    <profiles>

        <profile>

            <id>postgres</id>

            <dependencies>

                <dependency>

                    <groupId>org.postgresql</groupId>

                    <artifactId>postgresql</artifactId>

                    <version>${postgresql.version}</version>

                </dependency>

版本 Tomcat：8.5.29

档案：

    web: java $JAVA_OPTS -Dspring.profiles.active="datajpa,heroku" -DMISIC_ROOT="." -jar target/dependency/webapp-runner.jar --port $PORT target/*.war

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

确保你有这样的东西在你的pom.xml：&nbsp; &nbsp; &nbsp; &nbsp; <plugin>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.apache.maven.plugins</groupId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactId>maven-dependency-plugin</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <executions>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <execution>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <phase>package</phase>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <goals><goal>copy</goal></goals>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <configuration>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactItems>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactItem>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <groupId>com.github.jsimone</groupId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactId>webapp-runner</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>9.0.13.0</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <destFileName>webapp-runner.jar</destFileName>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </artifactItem>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </artifactItems>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </configuration>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </execution>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </executions>&nbsp; &nbsp; &nbsp; &nbsp; </plugin>

Answer 3

对我来说 1) 我在尝试设置 jhipster upp 以通过 git 部署而不是通过 jarfile 时遇到过这种情况。我拥有它是因为 Node.js buildpack 是在 java 之前启动的，所以我被迫使用heroku:buildpacks add --index 2 heroku/nodejsheroku:buildpacks add --index 1 heroku/java` 来设置它们，但即使在这个更改之后我仍然有同样的错误。2）然后我意识到我在 pom,xml 中有 jar 包装，而不是必需的 war 包装。将此值更改为 pom.xml 对我有帮助。
