Is there any best practises to share jacoco configuration between subprojects via kotlin gradle script?

[Hanno]

Don't know what config you mean exactly, but either a helper function in buildSrc project or a precompiled script plugin in buildSrc should be the right thing for the job

[Javier]

I have a precompiled plugin but I am applying it to the root.

[Javier]

First I was not merging all reports, but later I changed it to merge all so I can easily upload it to tools like codacy

[jeggy]

@Hanno Would you have a function in buildSrc/build.gradle.kts, or where would you put this configuration?

[Hanno]

No that wouldnt work, as code in buildSrc/build.gradle.kts is only available in this very file i think. You can just add a jacocoHelpers.kt in buildSrc/src/main/kotlin, as if it's a regular project. And use it afterwards in the whole build

[jeggy]

I have only managed to create objects within the buildSrc/.../*.kt which I then can use as variables.

But would it be possible to have a function which would do something like this in gradle?

fun setupJacoco() {
  // Gradle code below
  jacoco {
    toolVersion = "0.8.4"
    reportsDir = file("$buildDir/reports")
  }
}

[Hanno]

You would need to put the plugin dependency of for example jacoco into buildSrc as a imementation dependency, so that you can compile against. Afterwards, you can apply the jacoco plugin in your projects without specifying the version

[Hanno]

With that, yes, you can do sth like that :)

[Hanno]

Maybe the precompiled script stuff is better for your use case though

[jeggy]

not sure what is the best approach.
But my issue is I have a multi module project, and I have jacoco configuration with about 100 lines. Having 100 lines exactly the same in two different build.gradle.kts files within the same git repository, seems so wrong and I want to find what is the best way of structuring this.

[Javier]

precompiled plugin

[Javier]

so you can do in each module something like

plugins {
    my-jacoco-config-plugin
}

[jeggy]

having a precompiled plugin, would that be possible within the same git repository, or would you recommend to separate it?

[Javier]

or even do something like
allprojects {
apply<MyJacocoConfigPlugin>()
}

[jeggy]

same git repo = one intellij project *

[Javier]

you can create the precompiled plugin in buildSrc

[Javier]

and use it in all your subprojects or in the root build.gradle.kts

[jeggy]

Perfect. thanks. I guess I would find good guides by searching on google for "kotlin gradle scipr precompiled plugin"

I give up for today, will try again later

That would not be a property of the tool that is used, but of the user of the tool, you can abuse any tool instead of just reading its documentation. 😉
