Che: Eclipse Che extension doesn't get loaded using Docker for Mac

Created on 7 Dec 2016 · 6Comments · Source: eclipse/che

We did set CHE_ASSEMBLY env var correctly pointing to our extension che assembly, but no matter how we tried, it just did not show up in the eclipse che IDE. It did work if we switched to mac virtualbox docker.

Reproduction Steps:

build a helloworld eclipse che extension following these steps: https://eclipse-che.readme.io/docs/helloworld-extension. Or you can clone my examples: https://github.com/guiguan/che, and https://github.com/guiguan/che-helloworld-sample. Remember to mvn clean install _che-helloworld-sample_ first then _che_
export CHE_ASSEMBLY={path_to_che_assembly_assembly-main/target/eclipse-che-{che_version}/eclipse-che-{che_version}}
che start
visit localhost:8080, and create a workspace

Expected behavior:

"Hello World" notification should be displayed in the list of events

Observed behavior:

No "Hello World" printed

Che version: tried nightly, latest, 5.0.0-M7, and none of them worked on Docker for Mac
OS and version: macOS 10.12.1
Docker version: 1.12.3
Che install: Docker container

Additional information:

Problem started happening recently, didn't happen in an older version of Che: No
Problem can be reliably reproduced, doesn't happen randomly: Yes

Hi @guiguan,

We would need a bit more inputs in order to help you.
It seems you are doing right, but to be 100% sure we would need the outputs displayed when you are starting your Che from the CLI.

It can also just be a cache issue with the browser you are using.

For Google Chrome: open browser page with IDE, open chrome developer tools by F12, select "Network", mark checkbox "Disable cash". After that stop workspace, refresh page and start workspace again.
disable_cash

AndrienkoAleksandr on 7 Dec 2016

@AndrienkoAleksandr Yep, it works! Do we have to do this for every new extension?

guiguan on 7 Dec 2016

This checkbox works for all Chrome browser tabs and after restart browser too. If you don't want use it, you should periodically(when you have a problem) clean up cash by application domain:
for Google Chrome open development tools by F12 , move cursor to page reload button (with circle arrow above browser page) click and hold this button until appear drop-down menu, select in the menu "Empty Cache and Hard Reload". See more: http://superuser.com/questions/278948/clear-cache-for-specific-domain-name-in-chrome
Problems with cash is depends on tools which are you using for development. Sometimes all works fine, sometimes you have a problem with cash.

I see. Thanks for those nice tips, and I like your "cash", LOL. You can close this issue now :)
