danger-kotlin-android-lint-plugin

Show the Android lint errors on your PR with Danger Kotlin

Setup

Install and run Danger Kotlin as normal and in your Dangerfile.df.kts add the following dependency:

@file:DependsOn("com.gianluz:danger-kotlin-android-lint-plugin:0.1.0")

Then register your plugin before the danger initialisation and use the plugin:

register plugin AndroidLint

val danger = Danger(args)

// Default report
AndroidLint.report("/path/to/the/androidlint/result/file.xml")

You can report more than one lint file.

You can also keep tidy your DangerFile.df.kts using the following block:

androidLint {
    [...]
}

Or make your own custom report by manipulating all the issues found, for example failing the build at the first Fatal found in a specific module.

androidLint {
        // Fail for each Fatal in a single module
        val moduleLintFilePaths = find(
            moduleDir,
            "lint-results-debug.xml",
            "lint-results-release.xml"
        ).toTypedArray()

        parseAllDistinct(*moduleLintFilePaths).forEach {
            if(it.severity == "Fatal")
                fail(
                    "Danger lint check failed: ${it.message}", 
                    it.location.file.replace(System.getProperty("user.dir"), ""), 
                    Integer.parseInt(it.location.line)
                )
        }
    }
