Ubuntu14.04编译TradeFederation

  TradeFederation（后面简称TF）是android一个非常强大到测试框架，CTS，GTS，VTS上都用此框架进行各种测试，CTS测试case打包成jar，运行测试需要到配置文件以config(类似xml)形式一起放在本地PC，tradefederation利用java的反射机制执行case，并完成对结果到汇总。

  直接下载到源码包里面并不包含tradefederation代码，需要另外下载，而且编译过程中会有一些依赖库也不是android源码默认下载的，但是android官方已经提供，只是找到需要到依赖文件下载再重新编译就可以了。

1.TF官方介绍，以及build方法参考如下链接：

https://source.android.com/devices/tech/test_infra/tradefed/

TF源码：

https://android.googlesource.com/platform/tools/tradefederation/

2.参考官方提供到源码build说明，搭建好编译环境：

https://source.android.com/source/downloading

下载android源码（这里下载的分支为android-7.0.0_r33）

repo init -u https://android.googlesource.com/platform/manifest -b android-7.0.0_r33

3.源码下载完成后，在Ubuntu terminal里面进入源码下的tools目录，下载对应分支的TF

git clone https://android.googlesource.com/platform/tools/tradefederation -b android-7.0.0_r33

打开TF的Android.mk文件，需要依赖loganalysis。

LOCAL_JAVA_LIBRARIES := emmalib tools-common-prebuilt loganalysis

4.下载loganalysis到tools目录，与TF在同一个目录，loganalysis是TF的依赖库，如果没有编译汇报错(如最下方第八条)；

git clone https://android.googlesource.com/platform/tools/loganalysis -b android-7.0.0_r33

5.下载jline到android源码的external目录，Android.mk文件中有说明jline是静态库文件：

LOCAL_STATIC_JAVA_LIBRARIES := junit kxml2-2.3.0 jline-1.0 tf-remote-client

git clone https://android.googlesource.com/platform/external/jline -b android-7.0.0_r33

6.参考官方提供的build说明进行build：

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

• source build/envsetup.sh
• tapas tradefed-all
• make -j8

7.build完成
