我尝试在Ubuntu 15.10上构建Android源代码，但出现了错误。现在我想要你的帮助来构建Android源代码。
including ./tools/external/fat32lib/Android.mk ...
Starting build with ninja
ninja: Entering directory `.'
[ 0% 1/21542] Ensure Jack server is installed and started
Jack server already installed in "/home/smile/.jack-server"
Server is already running

然后我运行"$ java -Xmx2048m"命令，会得到一些输出：
