Question

我们的项目设置与how twitter has their finagle project configured非常相似，包含多个项目和一个project/Build.scala文件。

每当我们运行构建时，我们必须删除Ivy缓存，否则某些依赖项无法下载。

我们已经尝试关闭所有并行执行（我们认为这是某种冲突/锁定超时问题），但这似乎也没有解决它。有人有什么想法吗？

Answer 1

我似乎无法在以下任务中找到myResolvers的定义：

resolvers := myResolvers

此外，以下操作无效：

libraryDependencies ++= Seq(
  "com.example" %% "helloworld" % "5.5.4-SNAPSHOT" changing(),
)

上述示例失败的原因是changing()之后有逗号。

changing()版本不需要SNAPSHOT。请参阅SBT文档中有关依赖关系管理流程的Notes：

没有必要将SNAPSHOT依赖项标记为changing（）因为 sbt配置Ivy已经知道了。

在SBT 0.13.1中的多项目构建配置中下载失败？
