播放2.3.8 sbt，不包括登录 [英] play 2.3.8 sbt excluding logback

问题描述

在我的游戏2.3.8测试运行中，除了logback之外，我很难过.我尝试了许多排除规则，但似乎没有任何效果.我也无法在我的依赖树中找到它.我的sbt文件中的代码段:

I'm having a really hard time excluding logback from my play 2.3.8 test run. I've tried many exclude rules, but nothing seems to work. I also can't find it in my dependency tree. Snippet from my sbt file:

   .map(_.exclude("ch.qos.logback", "logback-core"))
   .map(_.exclude("QOS.ch", "logback-parent"))
   .map(_.exclude("", "logback-classic"))
}

由于某种原因，它不在依赖树中:

It's not in the dependency tree for some reason:

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

但是，当我运行测试时，它会显示出来！

Yet, when I run the test, it shows up!

$ activator test
[...]

我在机智的尽头.帮助.

I'm at my wits' end. Help.

推荐答案

我发现将排除项链接到增加的libraryDependencies上是行不通的，即

I have found that chaining the exclusions to the addition of libraryDependencies does not work, i.e.

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，请使用未记录的SettingKey.~=函数添加排除项(

Instead, add the exclusions using the undocumented SettingKey.~= function (http://www.scala-sbt.org/0.13.12/api/index.html#sbt.SettingKey) on the following line after adding new dependencies, i.e.

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"))
}

我不知道为什么会给出不同的行为，但是使用Play Framework 2.4.3和SBT 0.13.8可以成功排除经典的logback和slf4j.

I don't know why this gives different behaviour, but with Play Framework 2.4.3 and SBT 0.13.8 this successfully excludes logback-classic and slf4j.

请注意，您可以链接exclude和excludeAll方法调用，以避免重复调用map，因此您的代码可以简化为:

Note that you can chain exclude and excludeAll method calls to avoid repeatedly calling map so your code can be simplified to:

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"))
}

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已经包含来自Play插件的经典logback.您可以排除plugin.sbt中的库，但是如果您使用的是enablePlugins(PlayScala)(

After further investigation, I believe that this is required because the libraryDependencies already contain logback-classic from the Play plugin prior to parsing the build.sbt file. You can exclude the libraries in plugin.sbt, but if you are using the PlayScala plugin by enablePlugins(PlayScala)(https://www.playframework.com/documentation/2.5.x/NewApplication) this cannot be excluded so you have to add the exclusions separately.
