Question

我是hadoop的新手，我遇到了eclipse插件的问题。一切都安装和配置非常好（hadoop + java）但是当我导入eclipse插件时，我遇到了一个问题：

当我尝试运行ant命令时，我收到一个错误列表：

 [ivy:configure] :: Ivy 2.1.0 - 20090925235825 :: http://ant.apache.org/ivy/ ::
 [ivy:configure] :: loading settings :: file = /usr/local/hadoop/ivy/ivysettings.xml
 ivy-resolve-common:
 ivy-retrieve-common:
 [ivy:cachepath] DEPRECATED: 'ivy.conf.file' is deprecated, use  'ivy.settings.file'       instead
 [ivy:cachepath] :: loading settings :: file = /usr/local/hadoop/ivy/ivysettings.xml
 compile:
 [echo] contrib: eclipse-plugin
 [javac] /usr/local/hadoop/src/contrib/eclipse-plugin/build.xml:72: warning:   'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

 BUILD FAILED
 /usr/local/hadoop/src/contrib/eclipse-plugin/build.xml:72: Class not found: javac1.8

 Total time: 8 seconds

系统：

Windows 7 + Oracle VM Virtualbox v4.3.8 + Ubuntu 11.10 + hadoop-1.2.1 + eclipse
