java.lang.NoSuchMethodError caused by dependency conflict issue due to multiple versions of com.google.guava:guava:jar

[LeoAugust19]

Hi, we found multiple versions of com.google.guava:guava:jar exist in org.wisdom-framework:wisdom-test:jar:0.10.0. As shown in the following dependency tree, only com.google.guava:guava:jar:14.0 will be loaded, based on "Maven's nearest wins strategy", and the other versions will be shadowed during the packaging process.

However, method <com.google.common.base.Splitter: java.util.List splitToList(java.lang.CharSequence)> only included in the shadowed version com.google.guava:guava:jar:18.0. As a result, an exception will be thrown with the following stack trace when your project referencing the missing method.

Hello, I believe that updating to latest guava and updating the code to use the new API is the way to go.
