我使用一组 Linux 代理来构建我的应用程序。有时，代理会导致构建失败并出现以下错误：
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':ComponentThatReqBuildToolsRev23.0.3:preBuild'.
> failed to find Build Tools revision 23.0.3
因为我的构建代理是远程的（android 是预安装的 /opt/android-sdk-linux/tools/android），所以我无法预安装平台工具、构建工具等，所以我的项目中包含了一个 makefile。签出代码后，它会调用 makefile 中的一个方法：
#!/bin/bash
git submodule init
git submodule update
make updateSDK
# EOF
makefile中的方法是：
PACKAGES = "tools,platform-tools,build-tools-21.1.2,android-22,build-tools-23.0.3,android-21,extra-android-support,extra-android-m2repository,extra-google-m2repository,extra-google,google_play_services"
updateSDK:
(sleep 5 && while [ 1 ]; do sleep 1; echo y; done) \
| android --clear-cache update sdk --no-ui --all \
--filter $(PACKAGES)
在成功的情况下，来自 Bamboo 的日志显示：

Finished task 'Update Android SDK' with result: Success
但时不时地，它连接到错误的存储库，或者：
Fetching URL: https://dl.google.com/android/repository/repository-8.xml
或者
Fetching URL: https://dl.google.com/android/repository/repository-10.xml
除了 url 之外，它与上面的日志相同。它给出了这个错误：
Error: Ignoring unknown package filter 'build-tools-23.0.3'
在这些情况下，xml 文件不包含构建工具 23.0.3，即这个位：

我试过清除代理预构建的缓存，每次都尝试列出工具，使用 http 和 https，但无济于事。
基本上我的问题是，android update sdk 命令从哪里获取repository-XX.xml url？你能强制这个到最新版本吗？
