this Cucumber java junit project with Serenity . Only difference between master and slave is that Xvfb (headless browser) is working on Master but not on Slave, but since it looks a Maven or Cucumber error I doubt Xvfb has anything to with it.

What am I doing wrong?

Answer 1

Check https://github.com/temyers/cucumber-jvm-parallel-plugin There is stated:

As of cucumber-jvm:4.0.0 parallel execution is supported natively by cucumber. As such, upgrading to Cucumber 4.0.0 is recommended and this plugin is no longer maintained.

So consider leave cucumber-jvm-parallel-plugin

It looks like you have in your pom.xml something like

<tags>"~@ignore"</tags>

try to change it to

    <tags>
      <tag>~@ignore</tag>
    </tags>

BTW proper new style is now not @ignore check https://github.com/cucumber/cucumber/tree/master/tag-expressions#migrating-from-old-style-tags

Answer 2

The problem is maven version

Following format for list/set is support in maven 3.3.9 and onward versions but in lower versions it not supported.

<tags>val1,val2,val3...</tags>

But in maven version less than 3.3.9 , above is not supported

To fix make it backward compatible

<tags>
    <tag>val1</tag>
    <tag>val2</tag>
    .....
</tags>
