maven-build-scanner ignores -T arguments

[ArkadyKarev]

Hi, I'm trying to use maven-build-scanner with openjdk 15, and looks like that ignores mvn arguments.
For instance, when I use -T 8 or -T 1C, it shows only Thread #1

Am I doing something wrong? Please help me to figure out, because it seems to be a great tool.

And also when I'm running the build with mvn -T 1C argument,
in the cmd I can see
[INFO] Using the MultiThreadedBuilder implementation with a thread count of 8

but dashbord says
mvn -s /Users/arkady/.m2/settings.xml -T 8 -Pdefault clean test
like I run it with -T 8

Not sure what’s happened here. It only reports threads encountered. It could be your build somehow only runs single threaded, eg due to some dependency

@alexec thanks for your response. I tried to run it in several different project, and result is the same - it show only 1 thread. Could you give me advice how I can debug it, please? Or any other thoughts?

I face the same issue as well with the usage.
@ArkadyKarev were you able to resolve it?

Hi, nah, this project looks abandoned. I've decided not to use it

The graph is correct. Your build is running single-threaded, -T is not having an impact on it. It is reporting -T8 because that is what Maven is reporting, you're running one thread per core, and you have 8 cores.

You should expect a single-thread if, for example, you only have one Maven module in your project. This is what your example shows. If it still run single-threaded when you have multiple modules, then your modules are dependant on one another. That maybe just how you project works.

The goal of the project is speed up builds by providing insights. The insight I glean from your build is you assemble stage is long.

This is an OSS project, so help and support can only be given on best effort basis.

This project is not abandoned, but it is considered feature complete. It will continues to get security updates for example.
