Atom packages are not working inside docker


I am trying to install atom with java auto complete inside docker. Atom is installing and working fine, but autocomplte packages are not working. I am mainly looking for autocomplete when i write java code.
Atom Version: 21.2
Packages = “autocomplete-java-minus java-import-wiz java-plus java-classpath-registry busy autocomplete-java”

Docker File

FROM ubuntu:trusty
ENV DEBIAN_FRONTEND noninteractive
ENV ATOM_PACKAGES="autocomplete-java- autocomplete-java-minus java-import-wiz java-plus java-classpath-registry busy"

RUN apt-get update -y

RUN apt-get install -y git x11vnc wget python python-numpy unzip Xvfb firefox openbox geany menu &&
cd /root && git clone xxxxnoVNC.git &&
cd noVNC/utils && git clone xxxwebsockify websockify &&
cd /root &&
chmod 0755 / &&
apt-get autoclean &&
apt-get autoremove &&
rm -rf /var/lib/apt/lists/*
RUN add-apt-repository -y ppa:webupd8team/atom &&
apt-get update &&
apt-get install -y atom &&
apm install {ATOM_PACKAGES} && \ apm rebuild {ATOM_PACKAGES}
RUN curl -sL | sudo -E bash -
RUN apt-get install -y nodejs make gcc g++ gconf2 xdg-utils

su user -c “atom /home/user/”


It’s only autocomplete packages? Do they appear to be installing correctly? What about built-in autocomplete packages?


It’s installing properly but not loading when atom starts i guess. Directories names with packages are present in .atom/packages directory of users home directory.

Built in autocomplete packages are not auto completing java code.


How would you tell if a package is loaded? As it turns out, there’s an API method just for that. You can open the developer tools (View -> Developer -> Toggle developer tools), go to Console, and enter atom.packages.getActivePackages(). You can check for specific packages by filtering that list with a command like atom.packages.getActivePackages().filter( package => == "autocomplete-java")[0]. If autocomplete-java is activated, that code will show you the package object.
