问题描述
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，如下所示：
#install brew
> ruby -e$（curl -fsSL https://raw.github.com/mxcl/homebrew/go）
> brew --version
0.9.4
#news brew database
> cd $（brew --prefix）
> brew更新
> cd $（brew --prefix）&& git pull --rebase
＃get scala 2.10.0
> brew版本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代码运行器版本2.10.0 - 版权所有2002-2012，LAMP / EPFL
＃install play 2.1.0
> brew版本玩
2.1.0 git checkout 6a70797 Library / Formula / play.rb
...
> brew install play
>玩-version
玩！ 2.1.0（使用Java 1.6.0_43和Scala 2.10.0），http：//www.playframework.org
我创建了一个播放应用程序：
> cd~ /
>玩新的myapp
名称：myapp
创建一个简单的Scala应用程序
＃generate IntelliJ项目：
> cd myapp
>玩
> idea
[info]创建/Users/david/myapp/.idea_modules/myapp.iml
[info]创建/Users/david/myapp/.idea_modules/myapp-build.iml
并在IntelliJ中打开项目：
#Install IntelliJ 12 Ultimate Edition
从http://www.jetbrains.com/idea/下载它b $ b 12.0.4，Build＃IU-123.169
2月份建造13,2013
＃在IntelliJ中安装scala插件
运行IntelliJ，
首选项 - >插件 - >从存储库浏览 - >添加scala。
当前版本：0.7.134
＃在IntelliJ中打开myapp项目
文件 - >打开Project，选择目录/ Users / david / myapp
然后当我尝试运行单元测试时：
项目 - > myapp - >测试 - > ApplicationSpec - > （右键单击） - >运行
我收到此错误：
scala：未找到模块bigbrother的Сompiler库：右（项目）/右（scala-2.10.0）
实际上，有几个错误：
在文件中 - >项目结构 - >模块，有两个模块：
-myapp
-mypp-build
文件 - >项目结构 - >模块 - > myapp - > Scala
编译器库：scala-2.10.0 [未找到]
<<<错误
文件 - >项目结构 - >模块 - > myapp-build - >依赖关系：
scala-2.9.2
<<<错误
如果我更正了第一个错误如下，
文件 - >项目结构 - >模块 - > myapp - > Scala - >编译器库
并从下拉列表中选择第二个有效选项scala-2.10.0（版本2.10.0）。
然后，重新运行测试，产生错误：
'pre>
阶：输出路径/Users/david/bigbrother/project/target/scala_2.9.2之间共享：模块'bigbrother建造的生产，模块bigbrother建造'tests
目前，外部Scala编译器禁止输出路径共享。
禁用外部构建模式或配置单独的输出路径。
提示：您可以使用Project Artifacts来组合编译的类。
我需要做些什么才能让它发挥作用？
更新：基于Marius和alexwriteshere答案的解决方案
生成IntelliJ项目
> cd myapp
>玩
>想法no-sbt-build-module
（而不只是'想法'）
然后，
项目设置 - >库
选择Scala 2.9.2并点击 - 将其删除。
然后，
项目设置 - >模块 - > my_app - > Scala - > Scala编译器
在此下拉列表中，选择Scala 2.10.0写成红色。
移到列表顶部，然后选择用黑色/灰色写的Scala 2.10.0（版本2.10.0）。
注意
有时（我不知道为什么）选择Scala 2.10.0（版本2.10） .0）以黑色/灰色书写在下拉列表中不可用。可供我使用的
a解决方法如下：
项目设置 - >全局库 - > + - > Java
选择这些文件scala-compiler.jar，scala-library。 jar和scala-reflect.jar来自这个目录：/usr/local/Cellar/scala/2.10.0/libexec/lib/
选择确定。
给它命名为my scala 2.10.0 bundle。
然后再转到Project Settings - > Module - > my_app - > Scala - > Scala编译器
现在你有两个，你刚刚创建的我的scala 2.10.0包，标准的一个：Scala 2.10.0（版本2.10.0）用黑色/灰色写的。选择标准的，删除你创建的全局库。
我不知道为什么会这样，我真的不想花更多的时间来找到这个出。目前，这种解决方法对我有用。但如果你发现，可以随意添加评论。
这个问题可以通过生成想法项目来解决： / p>
$ play #start play from command line
[your-play-project] $ idea no-sbt-build- module
这将启用IntelliJ的Scala默认构建机制，这不会导致这些问题。
In my new mac OSX 10.8.3,I install scala 2.10.0, play 2.1.0 and IntelliJ12,and create a play project as follows:
#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
and I create a play application:
> 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
and open the project in IntelliJ:
# 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
Then when I try to run the unit test:
Project -> myapp -> test -> ApplicationSpec -> (right click) -> Run
I get this error:
scala: Сompiler library for module bigbrother not found: Right(Project) / Right(scala-2.10.0)
Actually, there are several errors:
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
If I correct the first error as follows,
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)".
Then, re-running the test, produces the error:
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.
What do I need to do to make it work?
Update: solution based on the answers from Marius and alexwriteshere
generate IntelliJ project with
> cd myapp
> play
> idea no-sbt-build-module
(instead of just 'idea')
then,Project Settings -> LibrariesSelect "Scala 2.9.2" and click on "-" to remove it.
then,Project Settings -> Module -> my_app -> Scala -> Scala-compilerin this dropdown list, there is selected "Scala 2.10.0" written in red.move to the top of the list, and select "Scala 2.10.0 (version 2.10.0)" written in black/grey.
Note
sometimes (I don't know why) the choice "Scala 2.10.0 (version 2.10.0)" written in black/grey is not available in the dropdown list.a workaround that works for me to make it available is as follows:Project Settings -> Global Libraries -> + -> Javaselect these files scala-compiler.jar, scala-library.jar and scala-reflect.jar from this directory: /usr/local/Cellar/scala/2.10.0/libexec/lib/select Ok.Give it the name "my scala 2.10.0 bundle".
then, go again to Project Settings -> Module -> my_app -> Scala -> Scala-compilernow you have both, the one you just created "my scala 2.10.0 bundle", and the standard one: "Scala 2.10.0 (version 2.10.0)" written in black/grey. select the standard one, and delete the global library you created.
I don't know why this happens, and I really don't want to spend more time finding this out. for the moment, this workaround works for me. but feel free to add a comment if you find out.
This problems can be solved by generating the idea project with:
$ play # start play from command line
[your-play-project] $ idea no-sbt-build-module
This will enable IntelliJ's default building mechanism for Scala, which won't cause these problems.
