Flutter构建在Ubuntu 19.10中失败

Question

我有一个Flutter应用程序，可以在另一台机器上完美构建（ubuntu 18.04）。现在我正在使用ubuntu 19.10，当我尝试使用flutter run命令运行此应用程序时，它会引发以下错误：

Launching lib/main.dart on Primo EF6 in debug mode...

Running Gradle task 'assembleDebug'... Done                         5.5s
Gradle task assembleDebug failed with exit code 1

我认为这是问题。我正在使用flutter v1.12.13 + hotfix.6

解决了这个问题。 .gradle目录上有一个权限问题，它是readonly。因此，更改权限可以解决此问题。
