scala – 在Mac OSX上运行IntelliJ中第一个playframework的例子
在我的新Mac OSX 10.8.3中,
我安装 scala 2.10.0,播放2.1.0和IntelliJ12, 并创建一个播放项目如下: #install brew > ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)" > brew --version 0.9.4 # update brew database > cd $(brew --prefix) > brew update > cd $(brew --prefix) && git pull --rebase # get scala 2.10.0 > brew versions scala 2.10.1 git checkout 79dc6f1 Library/Formula/scala.rb 2.10.0 git checkout 8ca07aa Library/Formula/scala.rb 2.9.2 git checkout 8896425 Library/Formula/scala.rb ... > git checkout 8ca07aa Library/Formula/scala.rb # 2.10.0 > brew install scala > scala -version Scala code runner version 2.10.0 -- Copyright 2002-2012,LAMP/EPFL # install play 2.1.0 > brew versions play 2.1.0 git checkout 6a70797 Library/Formula/play.rb ... > brew install play > play -version play! 2.1.0 (using Java 1.6.0_43 and Scala 2.10.0),http://www.playframework.org 我创建一个播放应用程序: > cd ~/ > play new myapp name: myapp Create a simple Scala application # generate IntelliJ project: > cd myapp > play > idea [info] Created /Users/david/myapp/.idea_modules/myapp.iml [info] Created /Users/david/myapp/.idea_modules/myapp-build.iml 并在IntelliJ中打开该项目: # Install IntelliJ 12 Ultimate Edition Download it from http://www.jetbrains.com/idea/ 12.0.4,Build #IU-123.169 Build on February 13,2013 # install scala plugin in IntelliJ run IntelliJ,Preferences -> plugins -> Browse from repositories -> add scala. current version: 0.7.134 # open myapp project in IntelliJ File -> Open Project,chose the directory /Users/david/myapp 那么当我尝试运行单元测试时: Project -> myapp -> test -> ApplicationSpec -> (right click) -> Run 我得到这个错误: scala: Сompiler library for module bigbrother not found: Right(Project) / Right(scala-2.10.0) 其实有几个错误: in File -> Project Structure -> Modules,there are two modules: -myapp -mypp-build File -> Project Structure -> Modules -> myapp -> Scala Compiler library: scala-2.10.0 [not found] <<< ERROR File -> Project Structure -> Modules -> myapp-build -> Dependencies: scala-2.9.2 <<< ERROR 如果我纠正第一个错误如下, File -> Project Structure -> Modules -> myapp -> Scala -> Compiler library and from the dropdown list I select the second valid option “scala-2.10.0 (version 2.10.0)”. 然后,重新运行测试,会产生错误: scala: Output path /Users/david/bigbrother/project/target/scala_2.9.2 is shared between: Module 'bigbrother-build' production,Module 'bigbrother-build' tests Currently external Scala compiler prohibits output path sharing. Either disable the external build mode or configure separate output paths. TIP: you can use Project Artifacts to combine compiled classes. 我需要做什么才能使其工作? 更新:基于Marius和alexwriteshere的答案的解决方案 生成IntelliJ项目 > cd myapp > play > idea no-sbt-build-module (而不是“想法”) 然后, 然后, 注意 有时(我不知道为什么)选择“Scala 2.10.0(版本2.10.0)”用黑色/灰色写入下拉列表中不可用. 然后再转到项目设置 – >模块 – > my_app – > Scala – >斯卡拉编译 我不知道为什么会发生这种情况,我真的不想花更多的时间找到这个.目前这种解决方法对我来说是有效的.但如果您发现,请随时添加评论. 解决方法
这个问题可以通过生成想法项目来解决:
$play # start play from command line [your-play-project] $idea no-sbt-build-module 这将使IntelliJ针对Scala的默认构建机制,这不会导致这些问题. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
