Question

为了测试，我创建了一个空项目，只有一个文件build.sbt只包含一行：

libraryDependencies += "org.openprovenance.prov" % "prov-interop" % "0.7.2"

如果我运行sbt update，它会因堆栈溢出而失败。最后几行看起来像这样（你可以想象重复的嵌套尝试来获取依赖关系）：

    at org.apache.ivy.core.resolve.ResolveEngine.fetchDependencies(ResolveEngine.java:731)
    at org.apache.ivy.core.resolve.ResolveEngine.fetchDependencies(ResolveEngine.java:748)
    at org.apache.ivy.core.resolve.ResolveEngine.doFetchDependencies(ResolveEngine.java:799)
    at org.apache.ivy.core.resolve.ResolveEngine.fetchDependencies(ResolveEngine.java:731)

我在maven项目中具有相同的依赖关系，并且下载依赖项没有任何问题。我怎样才能在sbt中解决这个问题？

Answer 1

在libraryDependencies的最开头声明以下依赖项：

"org.antlr" % "antlr-runtime" % "3.4"

更新：更好地使用antlr-runtime

更新2：给定的解决方案无法完全解决问题，此问题是由prov-interop依赖关系树中声明的递归依赖引起的。要解决它的声明：

libraryDependencies ++= Seq (
    "org.openprovenance.prov" % "prov-model" % "0.7.2",
    "org.openprovenance.prov" % "prov-interop" % "0.7.2" exclude("org.antlr", "stringtemplate"), // to resolve cyclic dependencies

sbt在stackoverflow失败，而maven工作正常
