Question

我尝试使用Heroku Maven Plugin部署Spring Boot应用。部署完成（mvn heroku:deploy）。但是当我检查Heroku应用程序日志（heroku logs --tail）时，我发现它没有找到Main类：

2017-10-03T23:50:45.702415+00:00 heroku[web.1]: Starting process with command `java $JAVA_OPTS -cp target/classes:target/dependency/* Main`
2017-10-03T23:50:48.064526+00:00 app[web.1]: Setting JAVA_TOOL_OPTIONS defaults based on dyno size. Custom settings will override them.
2017-10-03T23:50:48.068505+00:00 app[web.1]: Picked up JAVA_TOOL_OPTIONS: -Xmx300m -Xss512k -Dfile.encoding=UTF-8
2017-10-03T23:50:48.237240+00:00 app[web.1]: Error: Could not find or load main class Main
2017-10-03T23:50:48.314862+00:00 heroku[web.1]: State changed from starting to crashed
2017-10-03T23:50:48.301181+00:00 heroku[web.1]: Process exited with status 1

我没有Procfile（依赖默认值）。 Heroku Maven插件配置如下所示：

<plugin>
    <groupId>com.heroku.sdk</groupId>
    <artifactId>heroku-maven-plugin</artifactId>
    <version>1.2.0</version>
    <configuration>
        <processTypes>
            <web>java $JAVA_OPTS -cp target/classes:target/dependency/* Main</web>
        </processTypes>
    </configuration>
</plugin>

Main类路径是：

BASEPROJDIR/src/main/kotlin/com/virtualstand/ExplorerApplication.kt

您需要确保主类的类路径是正确的： -

<configuration>
    <processTypes>
        <web>java $JAVA_OPTS -cp target/classes:target/dependency/* com.virtualstand.ExplorerApplication</web>
    </processTypes>
</configuration>

使用heroku-maven-plugin将Spring Boot应用程序部署到Heroku - 崩溃的应用程序
