由于找到不同的文件内容，sbt程序集失败

Question

我正在尝试在GitLab中构建一个项目。在gitlab-ci.yml中，我运行了sbt程序集并遇到了烦人的异常。

[error] (soda/*:assembly) deduplicate: different file contents found in the following:
[error] /root/.ivy2/cache/io.netty/netty-buffer/jars/netty-buffer-4.0.42.Final.jar:META-INF/io.netty.versions.properties
[error] /root/.ivy2/cache/io.netty/netty-common/jars/netty-common-4.0.42.Final.jar:META-INF/io.netty.versions.properties
[error] /root/.ivy2/cache/io.netty/netty-codec-http/jars/netty-codec-http-4.0.42.Final.jar:META-INF/io.netty.versions.properties
[error] /root/.ivy2/cache/io.netty/netty-codec/jars/netty-codec-4.0.42.Final.jar:META-INF/io.netty.versions.properties
[error] /root/.ivy2/cache/io.netty/netty-transport/jars/netty-transport-4.0.42.Final.jar:META-INF/io.netty.versions.properties

我试图按照sbt-assembly: deduplication found error中的说明进行操作，看起来MergeStrategy已经到位，但例外仍然存在：

[info] Merging files...
[warn] Merging 'NOTICE' with strategy 'rename'
[warn] Merging 'README' with strategy 'rename'
[warn] Merging 'META-INF/NOTICE.txt' with strategy 'rename'

[warn] Merging 'META-INF/DEPENDENCIES' with strategy 'discard'
[warn] Merging 'META-INF/INDEX.LIST' with strategy 'discard'
[warn] Merging 'META-INF/MANIFEST.MF' with strategy 'discard'

我也尝试改变sbt版本，但问题仍然存在。

任何有关如何解决此问题的帮助都会很棒。

看着处处找不到任何解决方案。检查以下分辨率是否适合您，它对我不起作用：https://github.com/sbt/sbt-assembly/issues/297

我曾经遇到过类似的问题，有一些Java包和log4j，我做的是创建一个自定义合并策略，我只选择第一次出现。也许您可以调整该代码以适合您：

assemblyMergeStrategy in assembly := {
//  case PathList("javax", "servlet", xs @ _*)         => MergeStrategy.first
  case PathList("org", "apache", "commons", xs @ _*)        =>
 //   println(s"$xs")
    MergeStrategy.first
  case PathList(ps @ _*) if ps.last endsWith ".html" => MergeStrategy.first
  case "application.conf"                            => MergeStrategy.concat
  case "log4j.properties"                            => MergeStrategy.first
  case "unwanted.txt"                                => MergeStrategy.discard
  case x =>
    val oldStrategy = (assemblyMergeStrategy in assembly).value
    oldStrategy(x)
}

也许你改变了

 case PathList("org", "apache", "commons", xs @ _*)        =>
 //   println(s"$xs")
    MergeStrategy.first

你有问题的包（netty），你设法解决它：

 case PathList("io", "netty", xs @ _*)        =>
 //   println(s"$xs")
    MergeStrategy.first

最终我找到了解决此问题的方法。由于它是一个游戏项目，我可以使用激活器将其包装起来并创建一个包。我使用以下代码来创建包：wget https://downloads.typesafe.com/typesafe-activator/1.3.7/typesafe-activator-1.3.7.zip && unzip typesafe-activator-1.3.7.zip 1> / dev / null activator-dist-1.3.7 / activator -Dsbt.log.noformat = true -java -home /usr/lib/jvm/java-1.8-openjdk包清理编译测试dist
