1. Jack-server Error

First, the server on the jack compile error, modify OK, has been verified

Communication error with Jack Server ($), try ' jack-diagnose ' or see Jack server log
Failed to authenticate Jack server certificate. Try ' Jack-diagnose '
Failed to authenticate Jack server certificate. Try ' Jack-diagnose

1). $HOME/.jack-settings:

# Server Settings
server_host=127.0.0.1
server_port_service=8076//write yourself a, preferably a larger
server_port_admin=8077//write yourself a, preferably a larger

# Internal, do not touch
Setting_version=4

2). $HOME/.jack-server/config.properties:

#Fri Jan 10:21:41 CST 2018
jack.server.max-jars-size=104857600
Jack.server.max-service=4
jack.server.service.port=8076//Is the same as the value above settings
jack.server.max-service.by-mem=1\=2147483648\:2\=3221225472\:3\=4294967296
jack.server.admin.port=8077//Is the same as the value above settings
jack.server.config.version=2
jack.server.time-out=7200

Second, Jack_server compile error: (native ubuntu14.04 compile, only own an account, and only in the compilation of a set of code, and on the server may be multiple users at the same time in the compilation may differ)

Communication error with Jack Server ($), try ' jack-diagnose ' or see Jack server log

1. It is possible that the jack-server process already has, resulting in multi-tasking prompts that require kill jack-server, and delete the home directory. jack*

1). Enter the corresponding directory Prebuilts/sdk/tools, (kill Jack-server process is not complete) (you can skip this step)

./jack-admin Kill-server
./jack-admin uninstall-server2). If there is no effect after the first step, it is possible that the Jack-server process does not exit itself and requires a manual kill

PS Ax | grep Jack//view Jack-server process

Kill 9 XXXX//Kill Jack-server Process

RM-RF ~/.jack*//Delete the Jack file in the home directory

3). You can start compiling. (also automatically generated in the home directory. Jack-server and. Jack-settings, no tube)

The following is a scenario in which multiple users are compiled concurrently as a server (not verified)

2. The problem may be that Jack does not support multi-user compilation and needs to modify the port of Jack_server:

Solution: (not determined)

Modify the port numbers in both $home/.jack-settings and $home/.jack-server/config.properties (for example, to 8086/8087) to support simultaneous multi-user compilation

1). $HOME/.jack-settings:

# Server Settings
server_host=127.0.0.1
server_port_service=8076//8086
server_port_admin=8077//8087

# Internal, do not touch
Setting_version=4

2). $HOME/.jack-server/config.properties:

#Fri Jan 10:21:41 CST 2018
jack.server.max-jars-size=104857600
Jack.server.max-service=4
jack.server.service.port=8076//8086
jack.server.max-service.by-mem=1\=2147483648\:2\=3221225472\:3\=4294967296
jack.server.admin.port=8077//8087
jack.server.config.version=2
jack.server.time-out=7200

3). Change the file $home/.jack-server/config.properties permission from rwx to RW to solve the problem.

3. Compile the host memory for a small reason, the resolution is to tune the memory required for small compilation

Execute command generation into the Prebuilts/sdk/tools directory. Jack-server:./jack-admin install-server Jack-launcher.jar Jack-server-4.8.alpha.jar
Jack-launcher.jar, Jack-server-4.8.alpha.jar the names of these two files depend on the file name under your Prebuilts/sdk/tools directory,
