我想将我的Scala 项目升级到语言的2.11.1 版本。
当我更新了build.sbt 文件并尝试编译项目时，出现了以下错误信息：
[error] Modules were resolved with conflicting cross-version suffixes in {file:somePathTo}SomeProject:

起初，我认为这是因为我依赖于
Spray库，该库还依赖于parboiled，所以我在他们的用户列表上发布了一个问题：https://groups.google.com/forum/#!topic/spray-user/XY7ceh7a9t0，他们建议我尝试查看项目的依赖关系图表。似乎
parboiled不仅被Spray库使用，还被Cypher编译器使用(我依赖于Spraing Data Neo4j所以才要使用它)。
2.0和2.1版本都在使用Scala 2.10的parboiled。以下是
Neo4j Cypher compiler的两个版本链接：http://mvnrepository.com/artifact/org.neo4j/neo4j-cypher-compiler-2.0/2.0.3
http://mvnrepository.com/artifact/org.neo4j/neo4j-cypher-compiler-2.1/2.1.2
我在想是否有可能/被认为是安全的，从我的类路径中删除对此版本parboiled库(http://www.scala-sbt.org/0.13.5/docs/Detailed-Topics/Library-Management.html#exclude-transitive-dependencies)的传递依赖关系，并仅添加2.11。此外，如果有
Neo4j团队的人能告诉我是否有计划发布针对Scala 2.11编译的parboiled Cypher编译器版本，我将不胜感激。以下是我
