基于ubuntu16.04多用户编译android N(android 7.1)系统提示ninja_wrapper错误问题
Ubuntu 1604系统除了root,还有kandi和sundi两个用户,我先用kandi用户编译的,可编译通过,后面再用sundi的用户编译,出错信息如下:

此问题是在于Android N新特性中,将同一个使用过的TCP端口将视为唯一,所以遇到这种情况下需要修改两处文件。具体步骤如下:
1.修改用户根目录下的.jack-settings文件的两个端口
vi .jack-settings(注意:此处一定要用vi命令,改完后执行chmod600 .jack-settings;确保文件权限为-rw-------)
2.修改用户根目录下.jack-server目录下的config.properties文件的两个端口
但没有发现此文件,进入代码的prebuilts/sdk/tools目录下./jack-adminstart-server来生成config.properties文件,如果失败,以此尝试下面的操作
(1)./jack-admin stop-server
(2)./jack-admin kill-server
(3)./jack-admin uninstall-server
(4)./jack-admin install-server jack-launcher.jar jack-server-4.8.ALPHA.jar
(5)./jack-admin start-server
提示:程序会卡在此处,先等待两秒,让程序自动生成.jack-server/config.properties文件,然后执行Ctrl+C,此时就有config.properties文件了,修改此文件的端口号,需要与.jack-settings的端口相对应,而且不能和其他用户的一样。
重新编译还是提示错误,如下:

提示在/tmp/jack-Data.BU下没有权限创建jack-task-15702,用ll命令查看权限
rwx(Owner)r-x(Group)r-x(Other)
第1列表示文件的属性,这里为drwx------,这里有10格,第1格表示第一个小格是特殊表示格,表示目录或连结文件等等,d表示目录。后面依次表示文件owner、所在的group和other用户的权限,可读(r),可写(w),可执行(x),说明此目录只有owner(这里为kandi)有rwx权限,其他人没有访问的权限。
第2列表示文件个数。
第3列表示表示该文件或目录的拥有者,这里为kandi
第4列,表示所属的组(group)。每一个使用者都可以拥有一个以上的组,不过大部分的使用者应该都只属于一个组,只有当系统管理员希望给予某使用者特殊权限时,才可能会给他另一个组。这里也是kandi。
从上面的信息可以看出,除了kandi,其他用户,比如我编译出错的sundi用户没有权限访问,所以编译出错了。用chmod 777 jack-Data.BU修改,重新编译OK。修改后权限
