是否需要任何特定的sbt版本来编译cassandra-spark-connector

Question

我正在组装“Cassandra-Spark-Connector”。我只是按照以下步骤操作：

1. Git克隆连接器代码
2. 运行“sbt assembly”

在组装阶段，我收到以下错误：

我正在运行sbt 0.13.6

Answer 1

您始终可以通过运行来使用打包的sbt。

./sbt/sbt assembly

这将自动下载并使用有效版本的sbt。

Answer 2

构建Spark java连接器需要在plugins.bat中定义的sbt-assembly版本0.11.2。您可能在全局插件文件夹（〜.sbt \ 0.13 \ plugins）中安装了较新的sbt-assembly版本（版本0.13.0），这导致了此问题。 请重命名〜.sbt \ 0.13中的plugins文件夹并尝试再次构建它。
