构建 akka 失败"Error: could not retrieve JNA"

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，但没有成功。

我正在运行Windows 7, cygwin, sbt 0.11.0和scala 2.9.1。以下是我遵循的步骤序列:

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

最后一个命令失败，出现以下错误:

$ sbt.bat update
C:Users***Desktopakka>set SCRIPT_DIR=C:SBT
C:Users***Desktopakka>java -Xmx512M -jar "C:SBTsbt-launch.jar" update

使用sbt 0.7.7，我得到以下内容(它提示输入名称):

./sbt.bat update

C:Users***Desktopakka>java -Xmx512M -jar "C:Users***Desktopakkasbt-launch.jar" update

我做错了什么吗?你能帮我修一下吗?

Thanks in advance

Answer 1

注意，"SBT交互模式"一节中的akka编译指令似乎引用了旧的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(如没有为sbt会话设置代理)

Answer 2

我有同样的问题(在中央仓库中没有找到模块)，在我的网络接口上禁用ipv6解决了我的问题…到目前为止，通过ipv6访问repos似乎不太好

Answer 3

类似错误。在我的例子中，这是在需要https时使用http
