问题
I'm having an issue installing OpenNLP. I am hoping that the brilliance of the hive-mind of Stack can help me out here. I admit I'm not very familiar with using Java extensions/plug-ins, so any help would be greatly appreciated.
I have installed Maven. When I run mvn --version I receive the following:
Apache Maven 3.0.4 (r1232337; 2012-01-17 03:44:56-0500)
Maven home: /Users/[my_name]/apache-maven-3.0.4
Java version: 1.6.0_33, vendor: Apple Inc.
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac"
When I go to the OpenNLP directory, /Users/[my_name]/apache-opennlp-1.5.2, and run mvn clean install, I receive this error:

I don't completely understand this error. If someone could explain what I need to do to fix it, I would really appreciate it.

Execute the command from inside the opennlp folder: /Users/[my_name]/apache-opennlp-1.5.2/opennlp. For more details please check the building documentation.
