Subject compilation error
Date Mon, 07 Nov 2011 20:10:08 GMT
Hi,

Upon a fresh checkout of the latest trunk, I've encountered this compilation error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile
(default-compile) on project mahout-integration: Compilation failure
[ERROR] /Users/echiu/Downloads/mahout/trunk/integration/src/main/java/org/apache/mahout/cf/taste/impl/model/jdbc/ConnectionPoolDataSource.java:[39,13]
error: ConnectionPoolDataSource is not abstract and does not override abstract method getParentLogger()
in CommonDataSource

http://mail-archives.apache.org/mod_mbox/mahout-commits/201110.mbox/%3C16447367.24410.1319173217032.JavaMail.confluence@thor%3E

Does anyone happen to know how to get by this issue? Seems more like some kind of configuration/environment
issue to me. (Especially I didn't see anyone discussing this error on this mailing list).
My last build was about a month or so ago, I don't remember having any issues. 
Thanks much in advance!

Some info of my environment:
Apache Maven 3.0.3 (r1075438; 2011-02-28 09:31:09-0800)
Maven home: /usr/share/maven
Java version: 1.7.0-internal, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.6.8", arch: "x86_64", family: "mac"

I'm using hadoop-0.20.2-cdh3u0 and have $HADOOP_HOME defined in the env.

Command I ran:
mvn -DskipTests install (build failed on a test in core so I'm trying to build it with skipTests)
