编译卡桑德拉-火花连接器是否需要特定的sbt版本？

Question

我在组装“卡桑德拉-火花-连接器”。我只是按照下面的步骤：

1. Git克隆连接器代码
2. 运行"sbt程序集“

在组装阶段，我得到以下错误：

我正在运行sbt 0.13.6

Answer 1

通过运行，您可以始终使用打包的sbt。

./sbt/sbt assembly

这将自动下载并使用有效的sbt版本。

Answer 2

构建Spark连接器需要plugins.bat中定义的SBT-AssemblyVersion0.11.2。很可能您有一个较新的sbt程序集版本(ver )。安装在全局插件文件夹(~..sbt\0.13\ plugins )中，导致此问题。请将插件文件夹重命名为~..sbt\0.13，并尝试重新构建它。
