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!
