Maven找不到JRuby mojo描述符

我按照在this blog post by Sonatype中编写Ruby的Maven插件中的信的指示。Maven找不到JRuby mojo描述符

当我尝试运行mvn install（Maven的3.0.4），构建成功，但maven-plugin-plugin找不到任何魔力的描述：如果我试图撞击maven-plugin-plugin版本，任何高于2.4，构建

[INFO] ------------------------------------------------------------------------

失败，出现此错误消息：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:2.5:descriptor (default-descriptor) on project firstruby-maven-plugin: The API of the mojo scanner is not compatible with this plugin version. Please check the plugin dependencies configured in the POM and ensure the versions match. org.apache.maven.tools.plugin.scanner.MojoScanner.populatePluginDescriptor(Lorg/apache/maven/tools/plugin/PluginToolsRequest;)V -> [Help 1]

这里是tree输出到显示目录结构确定：

firstruby-maven-plugin 
├── pom.xml 
└── src 
    └── main 
     └── scripts 
      └── echo.rb 

3 directories, 2 files

任何想法为什么它不工作？

sonatype链接已经死了。 –

Codehaus jruby-maven-plugin似乎在5年前就被抛弃了。如果你使用的是Maven3，你可以尝试使用Maven2，但是我想看看https://github.com/torquebox/jruby-maven-plugins

感谢您的回复以及使用torquebox提供的插件的建议。我尝试使用Maven 2.2.1，它工作正常。 –
