git - 在 "Error: could not retrieve JNA"上构建 akka 失败

Question

我尝试按照网站 (http://akka.io/docs/akka/1.2/dev/building-akka.html) 上的描述构建 akka，但未成功。

我正在运行带有 cygwin、sbt 0.11.0 和 scala 2.9.1 的 Windows 7。以下是我遵循的步骤顺序:

git clone git://github.com/jboner/akka.git
git clone git://github.com/jboner/akka-modules.git
cd akka
sbt.bat update

最后一条命令失败并出现以下错误:

$ sbt.bat update

C:\Users\***\Desktop\akka>set SCRIPT_DIR=C:\SBT\

C:\Users\***\Desktop\akka>java -Xmx512M -jar "C:\SBT\sbt-launch.jar" update

使用 sbt 0.7.7，我得到以下信息(提示输入名称):

./sbt.bat update

C:\Users\***\Desktop\akka>java -Xmx512M -jar "C:\Users\***\Desktop\akka\sbt-launch.jar" update

我做错了什么吗？你能帮我解决这个问题吗？

提前致谢

请注意，“SBT interactive mode”部分中的 akka 编译说明似乎引用了一个旧的 sbt

% sbt
[info] Building project akka 1.2 against Scala 2.9.1
[info]    using AkkaParentProject with sbt 0.7.6 and Scala 2.7.7
                                       ^^^^^^^^^
                                       |
                                       --- no xsbt 0.10+ here... 

但是 Akka build.properties确实引用了 sbt 0.11.0。

考虑到 http://repo1.maven.org/maven2/net/java/dev/jna/jna/3.2.3/jna-3.2.3.pom是一个有效的地址，我建议检查任何互联网问题(比如没有为 sbt session 设置代理)。
