A way to easily increment major, minor or hotfix via gradle

versioning.gradle

def props = new Properties()
file("gradle.properties").withInputStream { props.load(it) }

int major
int minor
int hotfix

task readVersion() {
    doFirst {
        String version = props.getProperty("version")
        println "Current Version: " + version
        String[] versionParts = version.split('\\.')
        major = Integer.parseInt(versionParts[0])
        minor = Integer.parseInt(versionParts[1])
        hotfix = Integer.parseInt(versionParts[2].split('-')[0])
    }
}

task incrementMajor() {
    doFirst {
        String version = ++major + "." + minor + "." + hotfix + "-SNAPSHOT"
        props.setProperty("version", version)
        file("gradle.properties").withOutputStream { p -> props.store(p, null) }
        println "New Version: " + version
    }
}

incrementMajor.dependsOn readVersion

task incrementMinor() {
    doFirst {
        String version = major + "." + ++minor + "." + hotfix + "-SNAPSHOT"
        props.setProperty("version", version)
        file("gradle.properties").withOutputStream { p -> props.store(p, null) }
        println "New Version: " + version
    }
}

incrementMinor.dependsOn readVersion

task incrementHotfix() {
    doFirst {
        String version = major + "." + minor + "." + ++hotfix + "-SNAPSHOT"
        props.setProperty("version", version)
        file("gradle.properties").withOutputStream { p -> props.store(p, null) }
        println "New Version: " + version
    }
}

incrementHotfix.dependsOn readVersion
