How to add a plugin to tracecompass(an eclipse plugin project)?

I found this plugin which I want to try out. I am not familiar with eclipse. The repository says to add it as a plugin to tracecompass.I am using an already built binary of tracecompass. Is it possible to add a plugin to an already built eclipse project or do I have to add the plugin and then rebuild it from source? In any way, how do I add the plugin?

There are different ways to import the plugin.

Clone the repository outside of eclipse and import

1. git clone https://github.com/jonahkichwacoders/tracecompass-experiments.git

2. Select "File -> Import..."

3. Select "General -> Existing Projects into Workspace"
4. Next to "Select root directory" click "Browse..."
5. Navigate to the directory where you git clone'd the project earlier.

Clone and import from the Git perspective

1. Select "Window -> Perspective -> Other ..."
2. Select "Git"
3. Select "Clone a Git repository" from the "Git repositories" view
4. Select "Clone URI"
5. Paste https://github.com/jonahkichwacoders/tracecompass-experiments.git in the URI field and press "next"
6. Select the branch and finish
