安装使用的版本是 6.16.0, 已经过时, 7 版本已经出了.

安装使用 (Ubuntu)

环境: Ubuntu 16.04

Eclipse Che GitHub | 官方文档 | 官方安装文档

文档指出运行一个默认的 Eclipse Che, 在 Docker 下仅需如下命令.

1
docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v <path>:/data eclipse/che start

由于 Docker 进程使用 Unix Socket 而不是 TCP 端口, 需要 sudo. cd 到一个目录, 输入:

# 指定了版本 6.16.0, 最新版总是提示 not found.
sudo docker run -it -v /var/run/docker.sock:/var/run/docker.sock -v ~/Eclipse-Che:/data eclipse/che:6.16.0 start

# 目前用的版本
sudo docker run -it -v /var/run/docker.sock:/var/run/docker.sock -v ~/Workspace/Eclipse-Che/Eclipse-Che-6.16.0:/data -v ~/.m2:/home/user/.m2 eclipse/che:6.16.0 start

倒数第二行输出 INFO: (che start): Use: http://192.168.221.133:8080 即为浏览器访问地址.

踩坑

Workspace 中不显示且无法新建项目

如图.

而正常情况应该为:

出现该问题的原因: 访问的地址是 localhost:8080 或 127.0.0.1:8080, 正确应该访问本机ip+端口8080.

问题主要发生在 Windows 下, win 下终端直接提示的用 localhost 访问, 而 Linux 环境下则提示用本机ip访问所以没这个问题:

INFO: (che sstart): Use: http://192.168.221.133:8080
INFO: (che start): API: http://192.168.221.133:8080/swagger

解决方法查询自 GitHub Issue 12475:

qurben commented on 25 Feb

@skabashnyuk It seems to be related with #12476, before that CORS on wsagent was a bit more liberal.

When running the normal setup on Docker (the one described on the wiki and in this issue) and accessing Che via http://localhost:8080 the following happens:

In CheWsAgentCorsAllowedOriginsProvider the value of apiExternal is equal to http://10.0.75.2:8080/api (or whatever ip the container has on the Docker NAT). This sets allowedOrigins to http://10.0.75.2:8080. This causes the wsagent server to not respond with any CORS headers when a request is sent from http://localhost:8080 or http://127.0.0.1:8080 because the host does not match.

I am currently not well known enough with the code to propose a proper solution for this.

代码补全快捷键 (Ctrl + Space) 不起作用

症状是报错与警告正常显示, 但在编辑器按快捷键 Ctrl + Space 尝试弹出代码补全的小框框时没有反应.

解决方法: 把 Win10 输入法关了......

插件开发

官网的 Demo 安装

官网的双开ide的教程复现不了 (第二个 ide 也是显示不了工作区项目的问题), 作罢. 以下是 GitHub 上找到的方法.
