我正在尝试使用sbt-assembly将scala项目转换为可部署的胖jar .当我在sbt中运行我的程序集任务时,我收到以下错误:
Merging 'org/apache/commons/logging/impl/SimpleLog.class' with strategy 'deduplicate'
:assembly: deduplicate: different file contents found in the following:
[error] /Users/home/.ivy2/cache/commons-logging/commons-logging/jars/commons-logging-1.1.1.jar:org/apache/commons/logging/impl/SimpleLog.class
[error] /Users/home/.ivy2/cache/org.slf4j/jcl-over-slf4j/jars/jcl-over-slf4j-1.6.4.jar:org/apache/commons/logging/impl/SimpleLog.class
现在来自sbt-assembly文档:
如果多个文件共享相同的相对路径(例如,多个依赖项JAR中名为application.conf的资源),则默认策略是验证所有候选项具有相同的内容,否则出错.可以使用以下内置策略之一或编写自定义策略在每个路径的基础上配置此行为:
MergeStrategy.deduplicate是上面描述的默认值MergeStrategy.first选择classpath顺序中的第一个匹配文件MergeStrategy.last挑选最后一个MergeStrategy.singleOrError在冲突时出现错误消息MergeStrategy.concat简单地连接所有匹配的文件并包含结果MergeStrategy.filterDistinctLines也可以连接,但在此过程中会留下重复的内容MergeStrategy.rename重命名源自jar文件的文件MergeStrategy.discard只是丢弃匹配的文件
通过这个我设置我的build.sbt如下:
import sbt._
import Keys._
import sbtassembly.Plugin._
import AssemblyKeys._
name := "my-project"
version := "0.1"
scalaVersion := "2.9.2"
crossScalaVersions := Seq("2.9.1","2.9.2")
//assemblySettings
seq(assemblySettings: _*)
