无法在 Eclipse 中使用 Tomcat 服务器
Can't use Tomcat server in Eclipse
我已经安装了 Tomcat v8.0.35 并按照以下步骤进行了配置 (here). I have checked it and it's working fine: I went to localhost:(myport) and got this
现在我安装了 Eclipse Mars2 Enterprise Edition，New->Dynamic Web Project，我没有目标运行时，所以 New Runtime->Tomcat v8->给了安装文件夹->finish。现在项目已经创建，但是当我单击服务器选项卡时，它没有显示 tomcat。我收到此消息 "No servers available. Click this link to create a server"，但我无法使用 tomcat8 创建服务器。
创建 eclipse 项目时服务器处于开启状态
我不知道如何显示该文件，所以我将按 ctrl+c、ctrl+v（提前抱歉）。
因此 .log 文件中的警告和错误如下所示：
!ENTRY org.eclipse.egit.ui 2 0 2016-05-18 13:50:56.781
!MESSAGE Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Bogdan'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

本应有更多行，但我超出了字符数限制。
编辑 2
编辑 3：问题是我为 Mac 下载了 (tomcat) zip（是的，我现在感觉很糟糕）。非常感谢，@holidayCoder！
您的服务器配置不正确。单击此 link 以创建新服务器。删除所有已配置的服务器并添加新的 tomcat 服务器。
或者，
重新启动 Eclipse IDE 解决了问题。或者直接转到 ....metadata.plugins\org.eclipse.e4.workbench // 文件夹位置。并删除了 workbench.xmi 的所有内容并重新启动了应用程序。希望对你有用。
要在 eclipse 中将服务器添加到项目，请执行以下步骤：
1- 创建您的网络应用程序后
2-右键单击您的项目，然后按属性。
3- 然后移动 Java 构建路径
4-然后移动库选项卡
5- 按添加库按钮
6- 从弹出 select 服务器运行时
7- select tomcat 路径。
8- 你现在必须看到它
检查并重播它现在是否正常，我们可以另辟蹊径
我在 eclipse 上遇到了同样的问题 JUNO
与 Eclipse 集成的步骤
1 .转到 window>首选项>服务器>运行时环境>添加（浏览您的 提取 tomcat 二进制文件所在的位置）单击完成
转到windows>显示视图>服务器
单击添加新服务器>Apache>服务器版本，然后导航单击确定并完成
您将准备好服务器
因为有时 eclipse 不直接从服务器选项卡接受新服务器
希望对您有所帮助！
我已经安装了 Tomcat v8.0.35 并按照以下步骤进行了配置 (here). I have checked it and it's working fine: I went to localhost:(myport) and got this
现在我安装了 Eclipse Mars2 Enterprise Edition，New->Dynamic Web Project，我没有目标运行时，所以 New Runtime->Tomcat v8->给了安装文件夹->finish。现在项目已经创建，但是当我单击服务器选项卡时，它没有显示 tomcat。我收到此消息 "No servers available. Click this link to create a server"，但我无法使用 tomcat8 创建服务器。
创建 eclipse 项目时服务器处于开启状态
我不知道如何显示该文件，所以我将按 ctrl+c、ctrl+v（提前抱歉）。
因此 .log 文件中的警告和错误如下所示：

本应有更多行，但我超出了字符数限制。

编辑 3：问题是我为 Mac 下载了 (tomcat) zip（是的，我现在感觉很糟糕）。非常感谢，@holidayCoder！
您的服务器配置不正确。单击此 link 以创建新服务器。删除所有已配置的服务器并添加新的 tomcat 服务器。
或者，
重新启动 Eclipse IDE 解决了问题。或者直接转到 ....metadata.plugins\org.eclipse.e4.workbench // 文件夹位置。并删除了 workbench.xmi 的所有内容并重新启动了应用程序。希望对你有用。
要在 eclipse 中将服务器添加到项目，请执行以下步骤： 1- 创建您的网络应用程序后 2-右键单击您的项目，然后按属性。 3- 然后移动 Java 构建路径 4-然后移动库选项卡 5- 按添加库按钮 6- 从弹出 select 服务器运行时 7- select tomcat 路径。 8- 你现在必须看到它
检查并重播它现在是否正常，我们可以另辟蹊径
我在 eclipse 上遇到了同样的问题 JUNO
与 Eclipse 集成的步骤
1 .转到 window>首选项>服务器>运行时环境>添加（浏览您的 提取 tomcat 二进制文件所在的位置）单击完成
转到windows>显示视图>服务器
单击添加新服务器>Apache>服务器版本，然后导航单击确定并完成 您将准备好服务器
因为有时 eclipse 不直接从服务器选项卡接受新服务器
希望对您有所帮助！
