The version we use is 19.0. When we test on Axon.ivy Designer, everything works just fine. However, when we deploy on engine, it get exception at runtime:</p> <p><code>Caused by: java.lang.NoSuchMethodError: com.google.common.collect.Range.closed(Ljava/lang/Comparable;Ljava/lang/Comparable;)Lcom/google/common/collect/Range;</code></p> <p>After digging around, we discovered that there are 2 jars of guava in Axon.ivy engine's <code>lib/shared</code> directory: <code>guava-16.0.1.jar</code> and <code>guava-11.0.2.jar</code>. At runtime, somehow Axon.ivy Engine chooses to load <code>guava-11.0.2.jar</code> and ignore the other jar.</p> <p>My questions are:</p> <ul> <li>Why there two jars of two different version?</li> <li>Is there anyway we can use <code>guava-19.0</code> without overriding Axon.ivy engine's <code>lib/shared</code>?</li> </ul>Genzer HawkerTue, 10 May 2016 12:47:55 -0400https://answers.axonivy.com/questions/1762/why-there-are-two-guava-jars-in-axon-ivy-engine-s-lib-sharedjarlibraryconflict
