我在构建 Android AOSP 时不小心卸载了 jack 服务器

Question

我正在为 Android 构建 Android 代码在我的 ubuntu 14.04 机器上。

构建时我遇到了 jack 服务器的一些问题，最后我卸载了 jack 服务器（不小心）。

如何重新安装 Jack 服务器？

我尝试使用以下命令安装 jack 服务器：

jack-admin install-server jack-launcher.jar jack-server-4.11.ALPHA.jar

但是，我得到一个错误：

Jack server installation not found

请帮助我如何重新安装 Jack Server。

我也遵循了 Google 搜索结果中的指南，但到目前为止没有帮助。

更新-1 在尝试@gaoc 的答案后，每次尝试构建时都会出现以下错误。 :

Answer 1

显示已删除的软件包列表：

$ awk ' == "remove" { print , , }' /var/log/dpkg.log | tee list

如果您能在列表中找到删除的软件包，则重新安装：

$ sudo apt-get install --reinstall nameofpackage

Answer 2

以下是帮助我解决 jack 服务器问题的解决方案：

删除~/.jack-server目录和~/.jack.settings文件。这将在我们运行 make 命令时重新创建，所以不用担心。
使用此命令再次同步存储库（大约需要 30-40 分钟）：
```
repo sync -c --no-clone-bundle --no-tags -j4
```
此 -c 选项与 sync 命令将告诉 git 您真正需要的分支而不是所有存储库。 -jn（在我的例子中是-j4），这里的n指的是你想要的线程数。
现在像往常一样搭建环境，午餐和制作。
