未加载数据时无法获取工件。 IvyNode = org.scala-lang#scala-library;2.10.3答案

【问题标题】：impossible to get artifacts when data has not been loaded. IvyNode = org.scala-lang#scala-library;2.10.3未加载数据时无法获取工件。 IvyNode = org.scala-lang#scala-library;2.10.3

【问题描述】：

我在Spark-1.5.1的根目录下使用sbt assembly在windows上构建Spark源码时，用了半天，报错。

[error] (hive/*:update) java.lang.IllegalStateException: impossible to get artifacts when data has not been loaded. IvyNode = org.scala-lang#scala-library;2.10.3

Spark 版本 1.5.1

我安装的sbt版本0.13.9

有人可以帮助我吗？

【问题讨论】：

标签： scala apache-spark sbt

【解决方案1】：

我在 sbt 版本 0.13.8 中收到此错误

对我有用的修复方法是编辑 project/build.properties 以使用 sbt.version = 0.13.9

【讨论】：

我不明白，为什么？这个 sbt 版本可以正常工作几个月，但突然出现了一些与常春藤相关的神秘错误。

【解决方案2】：

我在另一个项目中遇到了同样的错误，根据this link，“它似乎与传递依赖项有关，并且手动添加排除引入了某种不一致。”

手动添加依赖为我修复了它。

【解决方案3】：

我在运行 ivy 时遇到了类似的错误，我在 ant/lib 中使用了 ivy-2.0.0.jar。通过将 ivy.jar 升级到 ivy-2.4.0 我的问题解决了。

这是我在运行 ivy 任务时发现的错误：

java.lang.IllegalStateException: impossible to get artifacts when data has not been loaded. IvyNode = junit#junit;4.4
