It seems like this line

Talaiot/library/core/talaiot/src/main/kotlin/io/github/cdsap/talaiot/TalaiotListener.kt

Line 118 in 17ff228

val executedTasks = gradle.taskGraph.allTasks.map { TaskName(name = it.name, path = it.path) }

is throwing an IllegalStateException https://github.com/gradle/gradle/blob/master/subprojects/core/src/main/java/org/gradle/execution/taskgraph/DefaultTaskExecutionGraph.java#L360
because graph is empty at that time, can we handle this scenario in the library, or I also appreciate if you help me fix our setup.
Thanks in advance!

Issue might be related to my Gradle version: 7.1.
When I downgrade my Gradle version to 7.0.2 it seems to be working well.

hi @mustafaberkaymutlu thanks for the report and the detailed description.
I was not able to reproduce the problem, I triggered a regression with 7.1 and was ok. I updated anyways the project with Gradle 7.1(#300) and deployed a new snapshot version. In case you have time you can test it please, more details here: https://github.com/cdsap/Talaiot#snapshots--

Trying to understand better the problem I checked if there are some relevant changes in the DefaultTaskExecutionGraph for 7.1 but I didn't see anything. Are you using Gradle Configuration Cache or another specific configuration?

Thanks again, and let me know

[mustafaberkaymutlu]

Hello,
Thanks for checking this so quickly!

We don't use configuration cache, however we do have build cache enabled.

I don't have a sample project to reproduce this issue at the moment, I will try again to find the root cause and then let you know. I'll also try with the snapshot version to see if there is a difference.
but there could be something else in our setup that is causing this, because we have other gradle plugins as well.

Best,
Mustafa.

@mustafaberkaymutlu I was able to reproduce locally the issue. It's only happening in the IDE, command line works well. We just published a new version:

plugins {
  id "io.github.cdsap.talaiot" version "1.5.1"
}

Can you verify please?

[mustafaberkaymutlu]

I just tried this,
When I use Talaiot 1.5.0 with Gradle 7.2 I can reproduce this issue,
and when I bump Talaiot to 1.5.1 then this issue doesn't happen, I think we can say your fix works!
Thanks for your help!

thanks for the heads-up, closing the issue
