Play 2.3.8 sbt排除logback

sbtplayframework-2.3phantom-dsl

我很难在Play 2.3.8的测试中排除logback。我尝试了许多排除规则，但似乎都不起作用。我也无法在我的依赖树中找到它。以下是我的sbt文件片段：

[...]
resolvers ++= Seq(
  "Typesafe repository snapshots" at "http://repo.typesafe.com/typesafe/snapshots/",
  "Typesafe repository releases" at "http://repo.typesafe.com/typesafe/releases/",
  "Sonatype repo"                    at "https://oss.sonatype.org/content/groups/scala-tools/",
  "Sonatype releases"                at "https://oss.sonatype.org/content/repositories/releases",

  "Websudos releases"                at "http://maven.websudos.co.uk/ext-release-local"
)

libraryDependencies ++= {
  val phantomVersion = "1.5.0"
  Seq(
    "net.jpountz.lz4" % "lz4" % "1.3.0",
    "org.xerial.snappy" % "snappy-java" % "1.1.1.6",
    "com.websudos" %% "phantom-dsl" % phantomVersion,
    "com.websudos" %% "phantom-testing" % phantomVersion % Test,
    "org.scalatestplus" %% "play" % "1.2.0" % Test,
    "org.cassandraunit" % "cassandra-unit" % "2.1.3.1" % Test
  ).map(_.exclude("org.slf4j", "slf4j-jdk14"))
   .map(_.excludeAll(ExclusionRule(organization = "ch.qos.logback")))
   .map(_.excludeAll(ExclusionRule(organization = "QOS.ch")))
   .map(_.excludeAll(ExclusionRule(artifact = "logback*")))
   .map(_.excludeAll(ExclusionRule(artifact = "logback-classic")))
   .map(_.exclude("ch.qos.logback", "logback-parent"))
   .map(_.exclude("ch.qos.logback", "logback-core"))
   .map(_.exclude("QOS.ch", "logback-parent"))
   .map(_.exclude("", "logback-classic"))
}

由于某些原因，它在依赖树中不存在：

$ activator "inspect tree test" |grep -i qos |wc -l
   0
$ activator "inspect tree test" |grep -i logback |wc -l
   0

然而，当我运行测试时，它确实显示出来了！

$ activator test
[...]

我感到无计可施，请帮助我。

我发现将排除操作链接到libraryDependencies的添加中不起作用，即：

libraryDependencies ++= {
  val phantomVersion = "1.5.0"
  Seq(
    "net.jpountz.lz4" % "lz4" % "1.3.0",
    "org.xerial.snappy" % "snappy-java" % "1.1.1.6",
    "com.websudos" %% "phantom-dsl" % phantomVersion,
    "com.websudos" %% "phantom-testing" % phantomVersion % Test,
    "org.scalatestplus" %% "play" % "1.2.0" % Test,
    "org.cassandraunit" % "cassandra-unit" % "2.1.3.1" % Test
  ).map(_.exclude("org.slf4j", "slf4j-jdk14"))
   .map(_.excludeAll(ExclusionRule(organization = "ch.qos.logback")))
   .map(_.excludeAll(ExclusionRule(organization = "QOS.ch")))
   .map(_.excludeAll(ExclusionRule(artifact = "logback*")))
   .map(_.excludeAll(ExclusionRule(artifact = "logback-classic")))
   .map(_.exclude("ch.qos.logback", "logback-parent"))
   .map(_.exclude("ch.qos.logback", "logback-core"))
   .map(_.exclude("QOS.ch", "logback-parent"))
   .map(_.exclude("", "logback-classic"))
}

相反，使用未记录的SettingKey.~=函数（http://www.scala-sbt.org/0.13.12/api/index.html#sbt.SettingKey）在添加新依赖项后的以下行中添加排除项，即可解决问题。

libraryDependencies ++= {
  val phantomVersion = "1.5.0"
  Seq(
    "net.jpountz.lz4" % "lz4" % "1.3.0",
    "org.xerial.snappy" % "snappy-java" % "1.1.1.6",
    "com.websudos" %% "phantom-dsl" % phantomVersion,
    "com.websudos" %% "phantom-testing" % phantomVersion % Test,
    "org.scalatestplus" %% "play" % "1.2.0" % Test,
    "org.cassandraunit" % "cassandra-unit" % "2.1.3.1" % Test
  )

libraryDependencies ~= { _.map(_.exclude("org.slf4j", "slf4j-jdk14"))
   .map(_.excludeAll(ExclusionRule(organization = "ch.qos.logback")))
   .map(_.excludeAll(ExclusionRule(organization = "QOS.ch")))
   .map(_.excludeAll(ExclusionRule(artifact = "logback*")))
   .map(_.excludeAll(ExclusionRule(artifact = "logback-classic")))
   .map(_.exclude("ch.qos.logback", "logback-parent"))
   .map(_.exclude("ch.qos.logback", "logback-core"))
   .map(_.exclude("QOS.ch", "logback-parent"))
   .map(_.exclude("", "logback-classic"))
}

我不知道为什么会出现不同的行为，但是在Play Framework 2.4.3和SBT 0.13.8中，这可以成功地排除logback-classic和slf4j。

请注意，您可以链接exclude和excludeAll方法调用，以避免重复调用map，从而简化代码：

libraryDependencies ++= {
  val phantomVersion = "1.5.0"
  Seq(
    "net.jpountz.lz4" % "lz4" % "1.3.0",
    "org.xerial.snappy" % "snappy-java" % "1.1.1.6",
    "com.websudos" %% "phantom-dsl" % phantomVersion,
    "com.websudos" %% "phantom-testing" % phantomVersion % Test,
    "org.scalatestplus" %% "play" % "1.2.0" % Test,
    "org.cassandraunit" % "cassandra-unit" % "2.1.3.1" % Test
  )

libraryDependencies ~= { _.map(_
  .exclude("org.slf4j", "slf4j-jdk14"))
  .exclude("ch.qos.logback", "logback-classic"))
}

编辑：经过进一步调查，我认为这是必需的，因为在解析build.sbt文件之前，libraryDependencies已经包含了来自Play插件的logback-classic。您可以在plugin.sbt中排除库，但如果您正在使用PlayScala插件通过enablePlugins(PlayScala)（https://www.playframework.com/documentation/2.5.x/NewApplication），则无法排除它，因此您必须单独添加排除。

谢谢你的回答。我暂时没有时间验证正确性。 - Foo L

有更好的方法来解决这个问题。首先，您应该确定是哪个依赖项导致了问题。

将以下内容添加到plugins.sbt中：

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.7.5")

现在你可以在sbt中使用一个新的命令，即whatDependsOn。使用它，你可以试用：

whatDependsOn ch.qos.logback logback-classic 1.1.1

然后我建议从确切的位置删除依赖项，而不是映射整个配置：

libraryDependencies ++= {
  val phantomVersion = "1.5.0"
  Seq(
    "net.jpountz.lz4" % "lz4" % "1.3.0",
    "org.xerial.snappy" % "snappy-java" % "1.1.1.6",
    "com.websudos" %% "phantom-dsl" % phantomVersion excludeAll(
      ExclusionRule(...)
    ),
    "com.websudos" %% "phantom-testing" % phantomVersion % Test,
    "org.scalatestplus" %% "play" % "1.2.0" % Test,
    "org.cassandraunit" % "cassandra-unit" % "2.1.3.1" % Test
  )
)
我已将插件从0.7.4升级到0.7.5，但仍然出现“[error] Not a valid command: whatDependsOn”的错误。 - kumetix
@kumetix 使用以下命令：sbt 'whatDependsOn ch.qos.logback logback-classic 1.1.1'。它的错误信息不是很友好，但确实有效。 - Michael Malone
@flavian 这仍然不能排除 logback-classic。 - Woodz
