I noticed a strange problem. I am able to run my test cases using Junit but when I am running using maven One of the test case is failing. It is complaining that Gson class def is not found.

I am able to see the Gson jar in Maven dependencies.

So I doubted that classpath is not including the Gson. So I ran maven with -X and noticed some clues.

I have a project which depends on Symbology project and this in turn uses Gson.
But now from this log I am seeing transitive dependencies are not getting included. So Gson class is not being found.

Here is the Symbology pom:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    Figured Out the Problem Finally after spending lot of time.

    The problem is when I am pushing the symbology artifact to repository it is not pushing the pom into repository. So when I am using the symbology artifact as dependency my project is not able to know what are the transitive dependencies.

    So I pushed my pom into repository along with jar and now it is able to get all the dependencies.

    HURRAYYYYYYYYYYYYYYYYY!!!!!!!!!!!!!!!!!!
