Eclipse plugin 使用eclipse构建hadoop插件

我正在使用Eclipse构建hadoop插件 hadoop版本是1.0.4 当我使用ant builder时，我得到如下错误

compile:
 [echo] contrib: eclipse-plugin
[javac] /home/shijieru/Downloads/HadoopInstall/hadoop-1.0.4/src/contrib/eclipse-plugin/build.xml:61: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

谁能告诉我这些问题的原因可能是什么？

您的问题似乎不是特定于hadoop的，但是目录权限—“无法创建父目录”是由javac输出的—请确保您对要编译的bin目录拥有适当的权限
