jack-server error when building in a docker container

[Robert Buckley]

I am able to build successfully when I build directly on my host machine, but if I start up a docker container and then manually build it from within there I get errors with jack server permissions.

Here is the error from the console:

[ 12% 5112/42202] Ensuring Jack server is installed and started

I can't tell what permissions jack-server wants.

I've created a docker image from ubuntu 16.04.

I downloaded the repos on my host machine, so I create a user for the docker image that matches my host system ids.

Thanks for the help in advance!

I am no expert here, but I know from experience that there are a few things to check with the makefile prebuilts/sdk/tools/jack_server_setup.mk which is most likely invoking the Jack directives causing your error:

• Sometimes it will uninstall/reinstall your Jack server, and by doing that will rewrite your configuration in ~/.jack-server like reverting the ports to the default ones. This does not seem to happen in your case
• The permissions of the file ~/.jack-server/config.properties must be 600 otherwise Jack will refuse to start a server
  
• It's sometimes a good idea to set the permissions of .jack-settings and .jack-server to someting not writable so that Jack cannot modify those settings

For the record, here is my tree view:

[-rw-------] ~/.jack-settings

[drwx------] ~/.jack-server/

├── [-rw-------]  client.pem
├── [-rw-------]  config.properties

Hello Robert,

Can you please try run  this command when you will get jack server error and then once again build AOSP.

export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"
out/host/linux-x86/bin/jack-admin kill-server
out/host/linux-x86/bin/jack-admin start-server

--------

Regards,

Chirag Vaghela
