Andy Seaborne commented on JENA-2234: ------------------------------------- The dependencyManagement section of the top level Jena POM sets the dependency and version for commons-codec to (currently) 1.15 https://github.com/apache/jena/blob/main/pom.xml#L353 You can also see that Jena controls the inclusion of commons-codec from other resources because it needs version 1.14 or later (currently1.15). You seem to have encountered the way that [maven resolves multiple dependencies of the same artifact|https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html]. It is not "later/newest"; it is "nearest" in the dependency tree, and random if they at the same depth. There are two ways to deal with this: * Directly depend on the artifact at the version required in your application. * Exclude the transitive dependency from systems with older copies. Best is to do both -- see example in Jena's top-level POM. common-compress has been very good at compatibility, as are all Apache Commons artifacts. A newer version should work. See JENA-1898. jena needs version 1.14 or later. > might need commons codec version to coexist with other libraries > ---------------------------------------------------------------- > > Key: JENA-2234 > URL: https://issues.apache.org/jira/browse/JENA-2234 > Project: Apache Jena > Issue Type: Improvement > Components: Build > Affects Versions: Jena 4.3.2 > Reporter: David Beaudet > Priority: Minor > > I'm experimenting with Jena and RDF4J in the same application.
