Run Eclipse Mars IDE inside Eclipse Che

What is Eclipse Che?

Eclipse Che is a developer workspace server and cloud IDE.
Codenvy hosts eclipse che workspaces with free accounts. You can simply create a codenvy account and try Eclipse Che. (https://codenvy.com/login/)
Since Eclipse Che is an open source project you can folk their github repository and start building from the source code. All the required instructions are provided their. (https://github.com/eclipse/che)
Now you have an idea about what is Eclipse Che and what eclipse che is for? Eclipse che provides a well explained documentation so you can learn anything from the begining 🙂 (https://eclipse-che.readme.io/docs/introduction)

Docker machine is an an environment is composed of machines powered by Docker or localhost.
A machine is a runtime whose stack is instantiated by a recipe.
Docker is a powerful and convenient implementation of machines providing near-instant activation, copy-on-write file system, and Dockerfile recipes for constructing custom stacks. Launch from our provided images, DockerHub, private registries, or through your own Docker files.
Your projects are mounted into the workspace.

I started my first GSOC (Google Summer Of Code) project this year with Eclipse foundation and I am currently developing a feature for Eclipse Che. If you are interested take a look at my project.(Eclipse CHE: Pair programming with Eclipse Che Cloud IDE) 😀
During the community bonding period which first thirty days we were supposed work with the community and get in touch with the code base.
During this time period I had to setup some tools for my local Development IDE which is Eclipse Mars.
My mentor Mr. Sun Seng David Tan (https://twitter.com/sunsengdavidtan) asked me setup Eclipse Mars inside Eclipse Che so we can share the same IDE.

Now we all know eclipse work spaces are built on Docker. So we need to configure the docker in order to get this done.
You can simply go to the workspaces on Eclipse Che and create a new workspace.

There you can write your own stack which will be used as the configuration for your workspace. You can find the docker image from here. (https://hub.docker.com/r/rnavagamuwa/eclipse-che-pair-programming-flux/)
If you are creating your own docker image simply use this in your Docker file.

Launch Eclipse Mars

Now everything is done. You only need to launch the ide.
Go to the cloud IDE and under consoles you can see a small icon called SSH.
Click on that icon and you will see the instructions. For an example if your get an instruction like this. (Default password will be “secret“)
```
ssh user@localhost -p 32775 [-i /path/to/your/private/ssh/key]
```
You just need to -X eclipse Mars Ide using the following command.

ssh user@localhost -p 32782 ./eclipse/eclipse -X

That’s it. 🙂 Feel freet to comment if you need to know anything else 😀

This is good for sharing configs but for development it’s always good to use a Cloud IDE(Eclipse Che) instead of Mars due to some reasons such as
