Release4k

compile 'com.github.christophpickl.kpotpourri:release4k:$versionKPotpourri'

Simple replacement for common release shell scripts using the Kotlin language. The main entry point is via the release4k(func: Release4k.() -> Unit) function which provides further (stateful) operations like:

• GIT interaction
• GitHub interaction
• Execute gradle or any other shell command
• Handles interactive I/O with user
• Version handling

Sample

    // =================================================================================================================

    val currentVersion = readVersionFromTxt(versionTxtFilename).toVersion2()
    val nextVersion = readVersion2FromStdin(
            prompt = "Enter next release version", 
            defaultVersion = currentVersion.incrementMinor()
    )
    val nextVersionString = nextVersion.niceString
    val syspropNextVersion = "-Dkpotpourri.version=$nextVersionString"

    // =================================================================================================================
    printHeader("VERIFY NO CHANGES")
    git(listOf("status"))
