由于找到不同的文件内容，sbt程序集失败
由于找到不同的文件内容，sbt程序集失败
提问于 2019-04-23 15:12:27
我正在尝试用GitLab构建一个项目。在gitlab-ci.yml中，我运行了sbt程序集，遇到了恼人的异常。
[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

[warn] Merging 'META-INF/INDEX.LIST' with strategy 'discard'
[warn] Merging 'META-INF/MANIFEST.MF' with strategy 'discard'我还试图更改sbt版本，但问题仍然存在。
任何关于我如何解决这个问题的帮助都将是很好的。

我曾经遇到过一些Java包和log4j的类似问题，我所做的是创建一个自定义的合并策略，在这个策略中我只选择第一个出现的地方。也许您可以调整该代码以使其适合您：
assemblyMergeStrategy in assembly := {
// case PathList("javax", "servlet", xs @ _*) => MergeStrategy.first
case PathList("org", "apache", "commons", xs @ _*) =>
// println(s"$xs")
MergeStrategy.first
case PathList(ps @ _*) if ps.last endsWith ".html" => MergeStrategy.first
case "application.conf" => MergeStrategy.concat
case "log4j.properties" => MergeStrategy.first
case "unwanted.txt" => MergeStrategy.discard
case x =>
val oldStrategy = (assemblyMergeStrategy in assembly).value
oldStrategy(x)
}也许如果你改变了
case PathList("org", "apache", "commons", xs @ _*) =>
// println(s"$xs")
MergeStrategy.first对于有问题的包(netty)，您可以设法解决它：
case PathList("io", "netty", xs @ _*) =>
// println(s"$xs")
