[ http://issues.apache.org/jira/browse/DBCP-68?page=comments#action_12435269 ] Phil Steitz commented on DBCP-68: ---------------------------------
Updating to collections 3.1 may cause dependency problems for some users. Per discussion on commons-dev, I would prefer to bundle the required classes in their 2.1 versions. There are two classes required - o.a.c.collections.LRUMap and o.a.c.collections.SequencedHashMap and only one dbcp class that depends on them - o.a.c.dbcp.datasources.SharedPoolDataSource. The collections classes have been deprecated, but still exist, in Collections 3.x. I propose that we take the versions from the collections 2.1 source and include them with package scope in o.a.c.dbcp.datasources, then remove collections dependency altogether. > [dbcp] Commons Collection dependency version clash when using Commons DBCP > via Maven2 > ------------------------------------------------------------------------------------- > > Key: DBCP-68 > URL: http://issues.apache.org/jira/browse/DBCP-68 > Project: Commons Dbcp > Issue Type: Bug > Affects Versions: 1.2 Final > Environment: Operating System: All > Platform: All > Reporter: Christoph Cenowa > Fix For: 1.2.2 > > > When using Maven2 to incorporate Commons DBCP 1.2.1 into your project a > transient dependency on Commons Collections 2.1 is added.
