从Manifest获取versionCode和versionName

Question

我有一个脚本可以自动增加 Manifest.xml 中的 versionName 和 versionCode 。 Android工作室使用 build.gradle中的 versionName 和 versionCode 。

的build.gradle ：

task('increaseVersionCode') << {
def manifestFile = file("src/main/AndroidManifest.xml")
def pattern = Pattern.compile("versionCode=\"(\\d+)\"")
def manifestText = manifestFile.getText()
def matcher = pattern.matcher(manifestText)
matcher.find()
def versionCode = Integer.parseInt(matcher.group(1))
def manifestContent = matcher.replaceAll("versionCode=\"" + ++versionCode + "\"")
manifestFile.write(manifestContent)
}

task('incrementVersionName') << {
def manifestFile = file("src/main/AndroidManifest.xml")
def patternVersionNumber = Pattern.compile("versionName=\"(\\d+)\\.(\\d+)\\.(\\d+)\\.(\\d+)\"")
def manifestText = manifestFile.getText()
def matcherVersionNumber = patternVersionNumber.matcher(manifestText)
matcherVersionNumber.find()
def majorVersion = Integer.parseInt(matcherVersionNumber.group(1))
def minorVersion = Integer.parseInt(matcherVersionNumber.group(2))
def pointVersion = Integer.parseInt(matcherVersionNumber.group(3))
def buildVersion = Integer.parseInt(matcherVersionNumber.group(4))
def mNextVersionName = majorVersion + "." + minorVersion + "." + pointVersion + "." + (buildVersion + 1)
def manifestContent = matcherVersionNumber.replaceAll("versionName=\"" + mNextVersionName + "\"")
manifestFile.write(manifestContent)
}

tasks.whenTaskAdded { task ->
if (task.name == 'generateReleaseBuildConfig' || task.name == 'generateDebugBuildConfig') {
    task.dependsOn 'increaseVersionCode'
    task.dependsOn 'incrementVersionName'
    }
}

如何将manifestCode从manifest转换为build.gradle？
