[转述] jruby 对 maven 的支持

之前开发了 java_side ，主要是便于 jruby 中使用基于 maven 管理的 java 三方包和基于 spring 管理的运行时服务，不过现在 jruby 1.6 以后 maven 这件事可以不必那么麻烦了，根据这篇blog ，我把自己试验的例子贴出来供参考：

 

• 下载

 

$ jruby -S gem install mvn:org.springframework:spring
Successfully installed mvn:commons-logging:commons-logging-1.1.1-java
Successfully installed mvn:org.springframework:spring-2.5.6-java
2 gems installed

• 使用

$ jruby -S irb
