NetBeans 项目在连接到 Tomcat 时卡住答案

【问题标题】：NetBeans project stuck while connecting to TomcatNetBeans 项目在连接到 Tomcat 时卡住
【发布时间】：2020-03-03 13:24:34
【问题描述】：

我正在尝试使用 NetBeans 8.2 部署一个带有 tomcat 的 Web 项目。

当我运行我的项目时，Tomcat 7 服务器运行良好，其日志显示服务器已启动，但 NetBeans 项目继续等待 Tomcat 服务器，等待 3 分钟后显示 “Tomcat 启动失败”

这是我的 Tomcat 日志

我不知道我做错了什么！

【问题讨论】：

您使用什么构建或启动工具？我不知道build-impl.xml 属于什么。
@f1sh Re "我不知道 build-impl.xml 属于什么"，它是 NetBeans 为基于 Ant 的项目生成的只读构建文件。
我不认为你做错了什么。您的日志显示 Tomcat 已成功启动，但 NetBeans 似乎没有意识到这一点。这可能是 NetBeans 错误NETBEANS-3903 Netbeans 11.2 fails to detect successful startup of Tomcat 9.0.31 的变体，该错误已在 NetBeans 12 中修复。报告该错误的人表示，该问题也存在于其他版本的 Tomcat 和 NetBeans 中。它也可能与操作系统相关，因为它是针对 Mac 报告的，我在 Windows 上没有遇到这个问题。你在 Mac 上运行吗？
@skomisa 是的，我正在使用 Mac。
好的，因为您使用的是 Mac，我认为您的问题与 Starting of Tomcat failed from Netbeans 重复，所以我投票结束这个问题。该问题提供了多种修复和解决方法，因此如果一种方法不起作用，请尝试其他方法。如果它们都不起作用，请相应地更新您的问题。

【解决方案1】：

在我的情况下，我认为问题出在我使用的 Tomcat 版本上，因此更改 tomcat 版本对我有用。

我使用的是Tomcat 7.0.100，我下载了Tomcat 7.0.56并将其添加到Netbeans中，然后在清理和构建我的项目后，我使用Deploy命令运行我的项目。
