使用OWL API 4.0.x的NoSuchMethodError

Question

I downloaded OWL API (4.0.1 and 4.0.2). But it needed plenty of dependencies that are nowhere mentioned. I downloaded dependency JARs from maven pom.xml file (found it somewhere for version OWL API 4.0.1). List of jars:

First of all, it was error with RDFFormat (need to add sesame lib, which was not in pom.xml. But I still have " NoSuchMethodError " errors. First one was

com.google.common.base.Objects.firstNonNull

(with Guava 17.0).I updated it to 18.0, now its

com.google.common.base.Platform.systemNanoTime

Here on stackoverflow is answer for this:

You most likely have both a recent version of Guava and either google-collect or a version of Guava prior to 3.0 on your classpath

But no, I dont have old Guava lib named google-collect(ions).

Maven dependencies are transitive. If you don't want to use Maven for some reason you'll need to include all of them. Here's the dependency tree for owlapi 4.0.2.

For the most part, your life will be much easier using Maven (or some other modern build tool). It deals with dependency issues like this so you don't have to. If you're stuck with ant for some reason you could also take a look at ivy .

Answer 2

Thank you for you responses. I use

-verbose:class

and found out, that package for that class is from

gephi-toolkit.jar

Tt has google-collection too ... so yeah, different versions.
