在travis support-v4 21.0上找不到android.support.v4.widget.DrawerLayoutImpl的类文件

Question

我们正在尝试对travis CI进行测试.我们有一个使用的类android.support.v4.widget.DrawerLayout.

当我们使用android支持v4库
build.gradle- >

targetSdkVersion: 19
`compile 'com.android.support:support-v4:20.0.0'`

.travis.yml

- build-tools-19.1.0
- android-19
- extra-android-support
- extra-google-google_play_services
- extra-google-m2repository

我们没有得到这个错误,但在使用

build.gradle - >

targetSdkVersion: 21
com.android.support:support-v4:21.0.+

.travis.yml

- build-tools-21.0.1
- android-21
- extra-android-support
- extra-google-google_play_services
- extra-google-m2repository

我们得到了错误

Travis甚至表明已下载并安装了Android支持库修订版21,但仍然出现上述错误.

更新:

我们试图在travis人员设置的VM上运行测试.

• 最初在机器上运行时,测试失败并出现相同的错误.
• 通过internal_impl-21.0.0.jar在support-v4 aar文件中找到的手动复制到我们的libs/目录并传递测试来尝试.
• 手动安装Android SDK tools 23.0.5在VM上并通过测试.

我们的项目.travis.yml有以下几个方面:

- tools - platform-tools - build-tools-21.1.1 - android-21 - extra-android-support - extra-android-m2repository - extra-google-m2repository 特拉维斯的测试仍然失败.
