Can't generate module graph

[Suresh]

Using the latest version of plugin in a kotlin multiplatform multi module project and createModuleGraph task fails with the following error.

> Task :createModuleGraph FAILED
List contains no element matching the predicate.
java.util.NoSuchElementException: List contains no element matching the predicate.

Hey, @sureshg could you check if you're using any filters? For example:

excludedConfigurationsRegex.set(".*test.*")
excludedModulesRegex.set(".*moduleName.*")
focusedModulesRegex.set(".*(projectName).*")

These might be triggering the issue. I think in this case it's specifically the excludedModuleRegex. I'll work on adding more explicit error messages for such scenarios too.

[Suresh]

Thanks for looking into it. No, i haven't used any filters. Here is the only config that get added to the root project.

moduleGraphConfig {
  readmePath = "./README.md"
  heading = "### Module Dependency"
}

[iury souza]

Interesting. Can please share the output of running

$ ./gradlew projects

from the root of your project?

i have the exact same problem in a multi-module android project

[Freedom Chuks]

works fine if it included in a singular module, but when added in the project level gradle file this error happens

[iury souza]

Hey @FreedomChuks & @sureshg , do you mind trying again on the latest version? 0.8.1
Cheers

[Freedom Chuks]

Certainly

[Freedom Chuks]

[Suresh]

@iurysza same..working now. Thanks for the quick fix.
