每次我想訪問我的應用程序通過瀏覽器

顯示如下消息因爲我無法訪問我的應用程序？與碼頭有任何兼容性錯誤？

Answer 1

你是如何部署應用程序你？用git push,mvn heroku:deploy,heroku deploy:war，還有別的嗎？

你pom.xml應該包括所有這一切圍繞着碼頭亞軍配置：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-dependency-plugin</artifactId> 
    <version>2.4</version> 
    <executions> 
     <execution> 
     <id>copy-dependencies</id> 
     <phase>package</phase> 
      <goals><goal>copy</goal></goals> 
      <configuration> 
       <artifactItems> 
        <artifactItem> 
         <groupId>org.eclipse.jetty</groupId> 
         <artifactId>jetty-runner</artifactId> 
         <version>9.2.7.v20150116</version> 
         <destFileName>jetty-runner.jar</destFileName> 
        </artifactItem> 
       </artifactItems> 
      </configuration> 
     </execution> 
    </executions> 
    </plugin> 

也就是說，確保它綁定到package目標。如果您使用的是git push，則檢查構建輸出以確保插件配置運行。

最後，檢查碼頭亞軍存在通過檢查毛坯：

$ heroku run ls target/dependency 

Answer 2

我設法解決部署到Heroku的問題。要格式化用CTRL + SHIFT + F快捷鍵我pom.xml文件在Eclipse中我的代碼如下：

問題

<plugin> 
    <groupId>com.heroku.sdk</groupId> 
    <artifactId>heroku-maven-plugin</artifactId> 
    <version>0.4.4</version> 
    <configuration> 
     <appName>cliente-mws-usp</appName> 
     <processTypes> 
      <web>java $JAVA_OPTS -jar target/dependency/jetty-runner.jar 
       --port $PORT target/*.war</web> 
     </processTypes> 
     <stack>cedar-14</stack> 
     <jdkVersion>1.7</jdkVersion> 
    </configuration> 
</plugin> 

問題是Heroku的只進行伸展java $JAVA_OPTS -jar target/dependency/jetty-runner.jar並把剩下的的命令--port $PORT target/*.war因爲我打破了路線。要撤消格式化並僅在一行上保留所有命令才能正常再次部署功能。

解決方案

<plugin> 
    <groupId>com.heroku.sdk</groupId> 
    <artifactId>heroku-maven-plugin</artifactId> 
    <version>0.4.4</version> 
    <configuration> 
     <appName>cliente-mws-usp</appName> 
     <processTypes> 
      <web>java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war</web> 
     </processTypes> 
     <stack>cedar-14</stack> 
     <jdkVersion>1.7</jdkVersion> 
    </configuration> 
</plugin> 

再次感謝你這麼多的幫助和解釋。
