postRelease hook

[ravikumar2026]

Hi Team,

We are trying to use postRelease hook to update the version in readMe with latest version which is just released. Below is the code, I have taken from examples, ` scmVersion { useHighestVersion.set(true) tag { initialVersion { _, _ -> "0.1.2" } }

checks {
    snapshotDependencies.set(true)
    uncommittedChanges.set(false)
    aheadOfRemote.set(false)
}
repository {
    pushTagsOnly.set(true)
}

hooks {
    postRelease {
        push()
        commit { releaseVersion, position -> "New commit message for version $releaseVersion" }
        custom { context -> println("$context")}
        fileUpdate {
            file("README.md") // repeat for additional files
            pattern = {previousVersion,context -> "version: $previousVersion"}
            replacement = {currentVersion,context -> "version: $currentVersion"}

        }
    }


}

} `

error :

` Execution failed for task ':release'.

Cannot invoke "Object.toString()" because the return value of "pl.allegro.tech.build.axion.release.domain.hooks.ReleaseHookFactory$CustomAction.apply(pl.allegro.tech.build.axion.release.domain.hooks.HookContext)" is null `

We are experiencing something similar. (For pre)

The way docs describe the scmVersion.hooks.pre is not valid kotlin. And will not compile. You have to specify something like you write, and I haven't gotten it to work at all. Atm I'm getting ClassLoader issues both on gradle 7.6 and gradle 8.3

I have not been able to test the hook at all. And just a way to do that would be nice; maybe dryRun is the thing to do, maybe not. I can't really tell from the docs.
