Parallel execution in maven project

1) Can't launch parallel execution. I tried it like this:

mvn gauge:execute -DinParallel=true

and also tried to add to maven plugin configuration

<inParallel>true</inParallel>

in both cases I see that specs are run sequentially - not in parallel, as expected.

2) Are parallel tests limited to parallel specs? Can I run parallel scenarios?

Hi Pavel,

You should be able to run Gauge specs in parallel with either of the methods above. It's really weird that Gauge is not running in parallel. Could you please send us the relevant logs? You should be able to get detailed logs by adding -X flag to mvn command.

As a workaround, could you also try passing -p in flags (-Dflags="-p") and give it a shot?

Gauge only runs specs in parallel, and not scenarios.

Works with -Dflags="-p"

Glad to know it works with -Dflags.

Ideally it should even work with -DinParallel. We use this flag (pom.xml#L50) in Gauge functional tests (which are written in Gauge) and it's working fine for us.

So it would be great if you could still send us the logs. That will help us investigate what's wrong.

Please also include the OS/arch of your machine along with the output of gauge -v.

OK, the problem is somewhere deeper. I've actually forgotten to mention about this error:

I'see it's expecting this classes folder for some reason? At least it is running in parallel with -DinParallel=true, but these errors are driving me mad. Anyways, I created this folder target/classes manually and not getting the error anymore, at the same time I'm not able to run specs in parallel, unless I specify the cli flag..

Not sure what helped eventually. I created manually the "classes" folder under target and I also used -U flag with maven. Currently -DinParallel=true is working as expected. I'm clueless.

Hey Mahendra,

I actually checked your POM.xml file and added/updated some dependencies, properties, etc. And it finally worked for me.
For some reason, the plugin seems to be failing, but if you execute from maven the command line: mvn test.
