Unresolved dependency SBT 0.13.0 after update
提问by user573215
Update SBT to 0.13.0:
将 SBT 更新到 0.13.0：
I have a couple of projects written with Scala 2.10.2 and build with sbt 0.12.4. As my OS is Ubuntu I used the SBT.deb package for installation of sbt 0.12.4. Everything fine. I built my projects with sbt.
我有几个用 Scala 2.10.2 编写并用 sbt 0.12.4 构建的项目。由于我的操作系统是 Ubuntu，我使用 SBT.deb 包安装 sbt 0.12.4。一切都很好。我用 sbt 构建了我的项目。
Yesterday I wanted to update sbt to version 0.13.0. I downloaded and installed the new .deb package. The projects configuration has not been changed.
昨天我想将 sbt 更新到 0.13.0 版。我下载并安装了新的 .deb 包。项目配置没有改变。

When runnging SBT after the update I get this failure:

How do I fix this dependency resolution?
如何修复此依赖项解析？
Suspects:
嫌疑人：
Other people had similar problems like this, but not the same. I don't think this is a problem of build definition incompatibility, do you? As far as I can see, SBT does not get to the point to read the project definition.
From where does this file should be retrieved? Shouldn't it be included in the SBT installation package? Also it looks like SBT / Ivy does only look inside the local Ivy repo. There is no SBT artifact with version 0.13.0 in the Maven Central Repository. Do I have to specify another repo or something?
And what about the Scala version? Shouldn't it be specified in the dependency definition? Do I have to specify the Scala version somewhere?
其他人不得不像类似的问题这样，但不一样的。我不认为这是构建定义不兼容的问题，是吗？据我所知，SBT 没有达到阅读项目定义的地步。
应该从哪里检索这个文件？不应该包含在SBT安装包中吗？此外，看起来 SBT / Ivy 只查看本地 Ivy 存储库。Maven Central Repository 中没有版本为 0.13.0 的 SBT 工件。我是否必须指定另一个回购或其他东西？
那么 Scala 版本呢？不应该在依赖定义中指定吗？我是否必须在某处指定 Scala 版本？

Prior to this problem I did not have this file. I added it trying to solve this problem:
在此问题之前，我没有此文件。我添加它试图解决这个问题：
sbt.version=0.13.0

I added some repos to ~/.sbt/repositories. This solved the problem. Now the file looks like this:
我添加了一些 repos 到~/.sbt/repositories. 这解决了问题。现在文件看起来像这样：
[repositories]
local
sbt-releases-repo: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
sbt-plugins-repo: http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
maven-central: http://repo1.maven.org/maven2/
You should look at this, too: http://www.scala-sbt.org/0.13.0/docs/Detailed-Topics/Proxy-Repositories.html
你也应该看看这个：http: //www.scala-sbt.org/0.13.0/docs/Detailed-Topics/Proxy-Repositories.html
But what still worries me is the question if this is an individual case for me and my system or if others have such problems, too. Did I misunderstand something? Because if I want to use a build tool, I don't think it should be my responsibility to care about the tool's dependencies after installation. That should be done by the tool's installation itself.
但仍然让我担心的是，这是否是我和我的系统的个别情况，或者其他人是否也有这样的问题。我是不是误会了什么？因为如果我想使用构建工具，我认为安装后不应该关心工具的依赖关系。这应该由工具的安装本身完成。
Of course it is my responsibility to care about my project's dependencies.
当然，关心我的项目的依赖是我的责任。

I ran into the same problem, turned out to be pebcak (of course), specifying 0.13 instead of 0.13.0 in project/build.properties
我遇到了同样的问题，结果是pebcak（当然），在project/build.properties中指定0.13而不是0.13.0
Stepping through the output in .sbt/boot/update.log was pretty useful and lead me to the issue (especially after I noticed that sbt ran ok in ~/ - downloading itself - I noticed the ivy.xml it was looking for didn't match the one it downloaded from that earlier attempt in ~/)
单步执行 .sbt/boot/update.log 中的输出非常有用并引导我解决问题（特别是在我注意到 sbt 在 ~/ 中运行正常之后 - 下载本身 - 我注意到它正在寻找的 ivy.xml 没有” t 匹配它从早期尝试中下载的那个 ~/)

I had a similar error message when my version of Java on OSX was 1.6. Updating to 1.8 fixed this issue for me.
当我在 OSX 上的 Java 版本为 1.6 时，我收到了类似的错误消息。更新到 1.8 为我解决了这个问题。
