Che: [build] mvn install in che-dev fails

Description

I am trying to build Che locally, following the description here : https://github.com/eclipse/che/wiki/Development-Workflow#build-che-using-docker

It fails with:

...

Look like the document is a bit outdated. @benoitf I think it's related to docker build of the dashboard. Do you know will it work if we mount /var/run/docker.sock into che-dev container?

[benoitf]

for building dashboard (and submodules) the help is there
and it includes the -Pnative \ flag
https://github.com/eclipse/che/wiki/Development-Workflow#build-and-run

[benoitf]

FYI I've updated the help page on the wiki for "docker build"

Thank you I'm testing it.

It failed again, this time with this:

Any ideas?

[benoitf]

Error code 137 is for memory issue so I assume there is no enough memory provided to the docker container in order to build GWT app

[benoitf]

@svenefftinge could you please check the allocated memory to the docker4mac in docker/preferences/advanced.

[svenefftinge]

ok, that seems to be it. Thanks.
