在没有sbt-dependency-graph所示的显式依赖的情况下拉出工件

Question

我差不多空SBT project here只有一个依赖：

• "org.apache.hadoop" % "hadoop-yarn-server-nodemanager" % "2.2.0"

检查此类工件的the pom，似乎它不依赖于任何guice-servlet工件。

然而，当我运行sbt dependency-tree时，我看到了不同的东西，它确实取决于guice-servlet神器：

user@laptop:~/workspace/pack$ sbt dependency-tree
[info] Loading project definition from /home/user/workspace/pack/project
[info] Set current project to pack (in build file:/home/user/workspace/pack/)
[info] eu.pepot.eu:pack_2.10:0.1 [S]
[info]   +-org.apache.hadoop:hadoop-yarn-server-nodemanager:2.2.0
[info]     +-com.google.inject.extensions:guice-servlet:3.0
[info]     | +-com.google.inject:guice:3.0
[info]     |   +-aopalliance:aopalliance:1.0
[info]     |   +-javax.inject:javax.inject:1
...

我错过了什么？

Answer 1

此依赖关系来自父pom，hadoop-yarn。

hadoop-yarn-server-nodemanager使用使用hadoop-yarn-server的{​​{1}}。这个pom有很多依赖，包括Guice。
