Bitrise无法安装缺少的android工具- Fabric

Question

由于找不到fabric的Gradle插件版本1.25.4，Bitrise step install-missing-android-tools失败。

但是正如你所看到的，这个版本是存在的，而且当我运行bitrise run 'dev'时，构建过程也是如预期的那样。

我对正在发生的事情一无所知。步骤日志：

似乎与jcenter.bintray.com有关--我刚试图打开链接的https://jcenter.bintray.com/io/fabric/tools/gradle/1.25.4/gradle-1.25.4.pom，但我得到了一个404 (未找到)。因此，即使这个版本存在，它似乎也不存在于jcenter上。也许它过去在jcenter上是可用的，但后来被删除了？

当然，如果gradle在本地缓存中可用，那么gradle不会失败，即使它在远程/url上不再可用，因为它可以使用本地缓存版本。
