versionCode自增脚本

定义版本号

System.setProperty("verName", "1.0.0")
ext.versionCofig = [
        "verCode"   : getVersionCode(),
        "buildCount": getBuildCount(),
]
android {
    compileSdk 32
    defaultConfig {
        applicationId "xxx"
        minSdk 21
        targetSdk 32
        versionName System.getProperty("verName")
        versionCode Integer.parseInt(versionCofig.verCode + versionCofig.buildCount)
    }
...

根据verName生成verCode

def getVersionCode() {
    StringBuffer sb = new StringBuffer()
    for (item in System.getProperty("verName").split("\\.")) {
        if (item.length() == 1) {
            //1位补0
            sb.append('0')
        }
        sb.append(item)
    }
    //转int去掉0开头
    return Integer.parseInt(sb.toString()).toString()
}

读取build自增开关

boolean getBuildLogicEnable() {
    Properties localProperties = new Properties()
    File file = project.rootProject.file('local.properties')
    if (!file.exists()) {
        file.createNewFile()
    }
    localProperties.load(file.newReader("UTF-8"))
    if (localProperties.getProperty("enable_build_logic") == null) {
        //未定义 默认开启
        return true
    }
    //配置enable_build_logic=0为关闭
    return localProperties.getProperty("enable_build_logic") as Integer as boolean
}

获取打包次数 alpha\release包通过git检查 自增

def getBuildCount() {
    //读取文件
    Properties localProperties = new Properties()
    File file = project.rootProject.file('version.properties')
    if (!file.exists()) {
        file.createNewFile()
    }
    localProperties.load(file.newReader("UTF-8"))
    //当前记录的verCode
    def locVerCode = "0"
    if (localProperties.getProperty("version_code") != null) {
        locVerCode = localProperties.getProperty("version_code")
    }
    //当前记录的buildCount
    def locBuildCount = "00"
    if (localProperties.getProperty("build_count") != null) {
        locBuildCount = localProperties.getProperty("build_count")
    }
    //逻辑启用开关
    if (getBuildLogicEnable()) {
        //仅在打生产包的时候执行自增
        def runTasks = gradle.startParameter.taskNames
        if ("assembleRelease" in runTasks) {
            //获取最新的commit
            def pullResult = ("git pull").execute().text.toString()
            print pullResult
            if (!pullResult.contains("Already up to date.")) {
                //冲突等的情况 中断任务
                return locBuildCount
            }
            def curCommitType = ("git log --no-merges --pretty=format:%s HEAD -1").execute().text.toString()
            if (curCommitType.startsWith("generator")) {
                return locBuildCount
            }
            //非generator提交 修改版本号
            if (Integer.parseInt(getVersionCode()) > Integer.parseInt(locVerCode)) {
                //verCode变化 即版本变化 buildCount归零
                locVerCode = getVersionCode()
                locBuildCount = "00"
            }
            //自增1
            def curBuildCount = ++Integer.parseInt(locBuildCount)
            //个位数补零 转string
            locBuildCount = curBuildCount > 9 ? curBuildCount.toString() : "0" + curBuildCount
            try {
                //存储自增后的打包次数及verCode记录
                localProperties.setProperty("version_code", locVerCode)
                localProperties.setProperty("build_count", locBuildCount)
                //写入
                FileOutputStream fos = new FileOutputStream(rootDir.getAbsolutePath() + "/version.properties", false)
                OutputStreamWriter opw = new OutputStreamWriter(fos, "utf-8")
                localProperties.store(opw, "")
                fos.close()
                //提交
                print(("git add ${project.rootProject.file('version.properties')}").execute().text.toString())
                print(("git commit ${project.rootProject.file('version.properties')} -m \"" +
                        "generator：v${System.getProperty("verName")}-build$locBuildCount-${locVerCode + locBuildCount}"
                        + "\"").execute().text.toString())
                print(("git push").execute().text.toString())
                print(("git pull").execute().text.toString())
                return locBuildCount
            } catch (Exception e) {
                e.printStackTrace()
            }
        }
    }
    return locBuildCount
}

根据当前分支与master提交次数对比差值

static def getCurBranchCommitCount() {
    int devCommitCount = Integer.parseInt((("git rev-list --max-parents=1 --count HEAD").execute().text.toString().replace(" ", "").replace("\n", "")))
    int masterCommitCount = Integer.parseInt((("git rev-list --max-parents=1 --count master").execute().text.toString().replace(" ", "").replace("\n", "")))
    def currentBranchName = "git rev-parse --abbrev-ref HEAD".execute().text.toString().trim()
    if (currentBranchName == "master")
        return masterCommitCount.toString()
    return (devCommitCount - masterCommitCount).toString()
}
