运行此命令：
mvn package -Pcdh4
这是maven中的错误：
[ERROR] Failed to execute goal on project hdfs-nfs-proxy:
Could not resolve dependencies for project
com.cloudera:hdfs-nfs-proxy:jar:0.8.1:
Could not find artifact jdk.tools:jdk.tools:jar:1.6 at specified path
/usr/lib/jvm/java-7-openjdk-amd64/jre/../lib/tools.jar -> [Help 1]
这是路径中/../返回目录的最后一行，路径应为：
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/tools.jar
我对maven不太了解或者它在哪里采用这条路径，我只是想按照一些构建说明进行操作。
使用Debug：

答案 0 :(得分：6)
您的JAVA_HOME应该指向JDK而不是JRE：tools.jar是位于JDK的lib目录中的lib。
答案 1 :(得分：1)
在Linux / Ubuntu框中安装Sun JDK并将JAVA_HOME指向已安装的JDK。
