在Jenkins构建过程中运行android模拟器

Question

我已经安装了Jenkins，并配置了在构建过程中运行模拟器的构建作业。但是，当我执行作业时，出现错误消息，表明jenkins用户没有运行kvm的权限。我该如何解决。

$ android list target

$ adb start-server
* daemon not running. starting it now on port 5973 *
* daemon started successfully *
$ adb start-server

Answer 1

我设法解决了这个问题。

1. 安装Qemu-KVM和cpu-checker：
   sudo apt install qemu-kvm cpu-checker
   

2. 检查KVM是否可用（以jenkins用户身份）：
   $ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
   
   

3. 创建组kvm并添加jenkins到该组：
   addgroup kvm
usermod -a -G kvm jenkins

4. 更改以下组的所有权/dev/kvm：
   chgrp kvm /dev/kvm

5. 创建udev规则：
   $ sudo nano /etc/udev/rules.d/60-qemu-kvm.rules
KERNEL=="kvm", GROUP="kvm", MODE="0660"

6. 重启
