sbt 使用“排除”排除工件

Question

我希望在 build.scala 中使用 sbt 模式从 jar 中排除工件。我看过一些帖子，但仍然没有头绪。

我想排除org/objectweb/asm

我累了

libraryDependencies ++= Seq(
...
"com.datastax.spark"  %% "spark-cassandra-connector"  % "2.0.3"  exclude("org.objectweb", "asm"), 
...)

Answer 1

你应该这样做

libraryDependencies ++= Seq(
...
"com.datastax.spark"  %% "spark-cassandra-connector"  % "2.0.3"  exclude("org.objectweb.asm", "org.objectweb.asm"), 
...)

你也可以这样做

libraryDependencies ++= Seq(
...
"com.datastax.spark"  %% "spark-cassandra-connector"  % "2.0.3", 
...).map(_.exclude("org.objectweb.asm", "org.objectweb.asm"))

如果你使用的是 sbt 0.13.8 及更高版本，那么你可以这样做

libraryDependencies ++= Seq(
...
"com.datastax.spark"  %% "spark-cassandra-connector"  % "2.0.3", 
...)

excludeDependencies += "org.objectweb.asm" % "org.objectweb.asm"
