从ANT到远程Tomcat部署获得500

Question

因此，我做了一个蚂蚁目标，将我们的应用程序部署到远程开发服务器上的Tomcat。部署到tomcat目标的ANT在本地Tomcat实例上工作100%完美。当我部署到远程服务器时，我得到一个fat 500错误，但是应用程序实际上部署到服务器上，我们可以很好地查看和使用它，就像没有错误一样。

超级酷，它的工作，但500错误导致蚂蚁目标说构建失败。如果ANT说构建失败了，我们的构建服务器也会失败，这意味着我们将有悲伤的红色点而不是快乐的绿色点。

我们正在使用最新和最伟大的蚂蚁与Tomcat v9。

下面是执行“”目标时所遇到的错误。

为了了解运行的内容，这里是ANT build.xml的重要部分。

谁知道为什么部署到远程，但仍然返回一个错误？我得到的错误有点模糊，所以我不知道我能做什么来调试它。

Answer 1

问题是服务器部署应用程序花费的时间太长了。Tomcat目标在某处等待服务器的响应，称应用程序已经部署。不幸的是，唯一的错误是500，没有其他事情可做。

解决方案，我只是重新安装Tomcat与版本9，从8，和一切都打开了更快，构建是成功的。

我不能说这是最好的答案，但我得到了一切，working.Hopefully，总有一天有人有更好的解决方案。
