ANT到遠程Tomcat部署獲得500

Question

因此，我製作了一個ANT目標，將我們的應用程序部署到遠程開發服務器上的Tomcat。 ANT部署到tomcat目標在本地Tomcat實例上完美工作。當我部署到遠程服務器時，出現fat 500錯誤，但應用程序實際部署到服務器，我們可以查看和使用它，就好像沒有錯誤一樣。

超酷，它的工作原理，但500錯誤導致ANT目標說生成失敗。如果ANT表示構建失敗，那麼Hudson也會構建我們的構建服務器，這意味着我們將會有悲傷的紅點而不是快樂的綠點。

我們在Tomcat v9中使用了最新最好的ANT。

下面是我執行「ant deploy-dev」目標時得到的錯誤。

要得到一個什麼樣的運行，這裏是ANT的build.xml的重要組成部分的想法。

<property environment="env"/> 
<property file="build.properties"/> 

<!-- Import --> 
<import file="${env.CATALINA_HOME}/bin/catalina-tasks.xml" optional="true"/> 

<!-- The deploy to Tomcat target --> 
<target name="deploy-local" description="Deploy the app to local Tomcat"> 
    <tomcat-deploy base-url="${url.base.local}"/> 
</target> 

<target name="deploy-dev" description="Deploy the app to dev Tomcat"> 
    <tomcat-deploy base-url="${url.base.dev}"/> 
</target> 

<target name="undeploy-local" depends="stop-local" description="Undeploy the app from local Tomcat"> 
    <tomcat-undeploy base-url="${url.base.local}"/> 
</target> 

<target name="undeploy-dev" depends="stop-dev" description="Undeploy the app from dev Tomcat"> 
    <tomcat-undeploy base-url="${url.base.dev}"/> 
</target> 

<target name="stop-local" description="Stop the app on local Tomcat"> 
    <tomcat-stop base-url="${url.base.local}"/> 
</target> 

<target name="stop-dev" description="Stop the app on dev Tomcat"> 
    <tomcat-stop base-url="${url.base.dev}"/> 
</target> 

<macrodef name="tomcat-deploy"> 
    <attribute name="base-url"/> 
    <sequential> 
     <echo>Deploying app to: @{base-url}</echo> 
     <deploy url="@{base-url}/manager/text" username="${username}" password="${password}" 
       path="/${app.name}" war="file:${war.path}.war"/> 
    </sequential> 
</macrodef> 

<macrodef name="tomcat-undeploy"> 
    <attribute name="base-url"/> 
    <sequential> 
     <echo>Un-deploying app from: @{base-url}</echo> 
     <undeploy 
       failonerror="no" 
       url="@{base-url}/manager/text" 
       username="${username}" 
       password="${password}" 
       path="/${app.name}" 
      /> 
    </sequential> 
</macrodef> 

<macrodef name="tomcat-stop"> 
    <attribute name="base-url"/> 
    <sequential> 
     <echo>Stopping the app at: @{base-url}</echo> 
     <stop url="@{base-url}/manager/text" username="${username}" 
       password="${password}" path="/${app.name}" /> 
    </sequential> 
</macrodef> 

任何人都知道爲什麼部署到遠程工作，但仍然返回錯誤？我得到的錯誤有點模糊，所以我不知道我能做些什麼來調試它。

Answer 1

問題在於服務器部署應用的時間太長。某處Tomcat Deploy目標正在等待來自服務器的表示應用程序已部署的響應。不幸的是，唯一的錯誤是500，沒有別的可以繼續。

這個解決方案，我只是簡單地將版本9的Tomcat重新安裝到8以上，而且一切都變得更快，構建成功。

我不能說這是最好的答案，但我得到了一切正常工作。希望有一天有人會有更好的解決方案。
