蚂蚁到远程Tomcat部署获得500

Question

因此，我制定了一个蚂蚁目标，将我们的应用程序部署到远程开发服务器上的tomcat。蚂蚁部署到Tomcat Target上在本地Tomcat实例上工作100％。当我部署到远程服务器时，我会收到一个胖500错误，但是该应用程序实际上将其部署到服务器，我们可以查看和使用它，就像没有错误一样。

超级酷可起作用，但500个错误导致蚂蚁目标说构建失败。如果Ant说构建失败了，那么Hudson我们的构建服务器也会失败，这意味着我们将拥有悲伤的红点，而不是快乐的绿色点。

我们正在使用Tomcat V9的最新和最伟大的蚂蚁。

以下是执行" Ant Deploy-Dev"目标时遇到的错误。

要了解正在运行的内容，这是蚂蚁构建的重要部分。xml。

有人知道为什么部署到遥控器有效但仍然返回错误？我得到的错误有点含糊，所以我不知道我该怎么做来调试它。

Answer 1

问题是服务器花费的时间太长，无法部署应用程序。Tomcat部署目标的某个地方正在等待服务器的响应，说该应用已部署。不幸的是，唯一的错误是500，没有其他事情要进行。

解决方案，我只是将tomcat重新安装了版本9，从8版开始，一切都更快地打开了，构建成功。

我不能真正说这是最好的答案，但是我得到了一切正常。希望有人有一个更好的解决方案。
