TestNG Emailable Report 0kb

Question

I'm trying to use TestNG EmailableReporter2 in my tests but the generated html file is 0kb and does not contain any tests.

I've added

<listeners>        
    <listener class-name="org.testng.reporters.EmailableReporter2" />
</listeners>

To my testng.xml, the report file is generating without issues, but does not contain any data.

I have a few hunches, because before this was working fine for me. Could this be because something's wrong with my pom.xml? (Previously I haven't used maven in my automation projects)

Not likely, but could this be because of some proxy issues?

My pom.xml is as follows:

I believe your question was answered in the issue https://github.com/cbeust/testng/issues/1412

You have not specified the testng.xml location to maven.

Check: https://maven.apache.org/surefire/maven-surefire-plugin/examples/testng.html

Feel free to reopen the issue if it doesn't work and if you think it is a testng issue.
