Getting Started with Active Objects Tutorial with Confluence - error in unit tests

[Yagnesh Bhat]

Hi I am trying to run this tutorial in Confluence 5.7 and sdk 5.0.13

https://developer.atlassian.com/docs/atlassian-platform-common-components/active-objects/getting-started-with-active-objects

I am using AO 0.20 which is good and the servlet in the above tutorial works fine. 

The problem is while running the Test Class mentioned in the last part of step 12, I get these exceptions, highlighted in bold below:

Running ut.com.unittest.yagnesh.TodoServiceImplTest

Note I am using Java 8. and I found there is no need to download these dependencies as mentioned in the tutorial:

<!-- Google Collections, useful utilities for manipulating collections -->
<dependency>
<groupId>com.google.collections</groupId>
<artifactId>google-collections</artifactId>
<version>1.0</version>
<scope>provided</scope>
</dependency>

as 5.0.13 provided the new library of guava by default. 

And I am also using the hsqldb dependency (1.8.0.10) as mentioned in the tutorial

Is there anything I am missing? Please let me know soon.

I am also facing the same issue. Did anyone find the solution for this? For one instance, it fixed if I add the below dependency and same is not working in other places. Not sure what else is conflicting with this dependency.

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>23.0</version>
    <scope>test</scope>
</dependency>

It might be worth asking support or going to the appropriate dev doc page and commenting there as well.

Can someone please guide me on this? We need to make sure that we have a proper procedure to Unit Test the AO related code in our plugins.
