Duplicate class error while building cloudcommerceprocurement jar

[pjain1]

I have been following this - https://github.com/googlecodelabs/gcp-marketplace-integrated-saas/tree/master/java to generate cloudcommerceprocurement jar

I did the following -

wget 'https://cloudcommerceprocurement.googleapis.com/$discovery/rest?version=v1' -O discovery.json
python -m pip install google-apis-client-generator --user
~/Library/Python/2.7/bin/generate_library --input=discovery.json --language=java --output_dir=procurement

In the pom file of procurement project the version for google-api-client was set to 1.25.0-SNAPSHOT so I changed it to 1.25.0.

Now when I run mvn clean install, I get the following errors -

It worked after I made this change in pom.xml of procurement project -
<sourceDirectory>.</sourceDirectory> to <sourceDirectory>com/</sourceDirectory>
