Answer 1

If you are building Android N then Jack config files is changed. apply above suggested configs by following Transition Guide.

find the config you want to change, find where it moved from $HOME/.jack and change it there.

Transitioning from server 1.1 (e.g. Marshmallow) to server 1.3 (e.g. N)

The old Jack server used a $HOME/.jack configuration file. It has now replaced by a $HOME/.jack-settings and a $HOME/.jack-server/config.properties.

If those new files do not exist,

run jack-admin start-server and they will be created.

If you had custom settings in your $HOME/.jack, here's how to adapt those.

Step 1

SERVER_PORT_SERVICE=XXXX Replace with SERVER_PORT_SERVICE=XXXX in $HOME/.jack-settings and jack.server.service.port=XXXX in $HOME/.jack-server/config.properties.

Step 2

SERVER_PORT_ADMIN=YYYY Replace with SERVER_PORT_ADMIN=YYYY in $HOME/.jack-settings and jack.server.admin.port=YYYY in $HOME/.jack-server/config.properties.

Step 3

SERVER_NB_COMPILE=N Replace with jack.server.max-service=N in $HOME/.jack-server/config.properties.

Extra Settings

SERVER_TIMEOUT=ZZ You can replace with jack.server.time-out=ZZ, but it is recommended to keep the default setting of “7200” (2 hours).

Other settings in the $HOME/.jack configuration file do not need to be copied. You should still keep your $HOME/.jack configuration file for the old Jack server because both server versions can run simultaneously.

Answer 2

I've just run into same problem.

The problem is that virtual machine which runs jack doesn't have enough memory.

You can try to edit jvm command:

JACK_VM_COMMAND=${JACK_VM_COMMAND:="java -Xmx4096m"}

or to decrease number of parallel jack compilations

SERVER_NB_COMPILE=2

in ~/.jack file.

You can read jack documentation for details.

EDIT: Changing .jack file didn't work for me. After digging a little deeper I found that jack server is started with out/host/linux-x86/bin/jack-admin script and it's parameters can be passed with JACK_SERVER_VM_ARGUMENTS environment variable.

So my solution was to set it and restart jack server before building 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

Just try add

export ANDROID_JACK_VM_ARGS="-Xmx8192m -Xms512m -Dfile.encoding=UTF-8 -XX:+TieredCompilation"

to the end of .bashrc and reboot Linux

Answer 4

jack_server_setup.mk under prebuilts\sdk\tools

ifneq ($(ANDROID_JACK_VM_ARGS),)
jack_vm_args := $(ANDROID_JACK_VM_ARGS)
else
jack_vm_args := -Dfile.encoding=UTF-8 -XX:+TieredCompilation
endif
.....
ifneq ($(dist_goal),)
    $(hide) mkdir -p "$(DIST_DIR)/logs/jack/"
    $(hide) JACK_SERVER_VM_ARGUMENTS="$(jack_vm_args) -Dcom.android.jack.server.log.file=$(abspath $(DIST_DIR))/logs/jack/jack-server-%u-%g.log" $(PRIVATE_JACK_ADMIN) start-server 2>&1 || exit 0
else
    $(hide) JACK_SERVER_VM_ARGUMENTS="$(jack_vm_args)" $(PRIVATE_JACK_ADMIN) start-server 2>&1 || exit 0
endif

So we can export

ANDROID_JACK_VM_ARGS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"

to config jack args. And then run this below:

./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server

Answer 5

goto build/core/config.mk and change heap size in

APICHECK_COMMAND := $(APICHECK) -JXmx8g -J"classpath $(APICHECK_CLASSPATH)"

then it will work fine.
Other solutions didn't help me.
