编译安卓7.1源码报错 ninja: build stopped: subcommand----解决办法

编译过程中出错：
ninja: build stopped: subcommand failed
.build/core/ninja.mk:148: recipe for target ‘ninja_wrapper’ failed
make: *** [ninja_wrapper] Error
解决办法：
打开prebuilts/sdk/tools/jack-admin 文件，找到JACK_SERVER_VM_ARGUMENTS变量，
1、添加参数 -Xmx8192m，
JACK_SERVER_VM_ARGUMENTS="${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 - XX:+TieredCompilation -Xmx8192m}"

2、然后重新启动Jack server

prebuilts/sdk/tools$ ./jack-admin stop-server

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