I want to increase the version number of my project from 1.0.0. to 1.0.1 automatically whenever a new build is made through bash command. I only need to increase path number and others i will be increasing manually during manual build.
i want to change
this :
version=1.0.0
to This:
version=1.0.1
using gradle task. any help that how can i do this . Is there any way to update this using regex or using substring function.
Here's a custom task for version bumps in Gradle (Android project):
class Version {
private int major
private int minor
private int patch
private int code
Version(int code, String version) {
this.code = code
def (major, minor, patch) = version.tokenize('.')
this.major = major.toInteger()
this.minor = minor.toInteger()
this.patch = patch.toInteger()
}
@SuppressWarnings("unused")
void bumpMajor() {
major += 1
minor = 0
patch = 0
code += 1
}
@SuppressWarnings("unused")
void bumpMinor() {
minor += 1
patch = 0
code += 1
}
@SuppressWarnings("unused")
void bumpPatch() {
patch += 1
code += 1
}
String getName() { "$major.$minor.$patch" }
int getCode() { code }
}
tasks.addRule("Pattern: bump<TYPE>Version") { String taskName ->
if (taskName.matches("bump(Major|Minor|Patch)Version")) {
task(taskName) {
doLast {
String type = (taskName - 'bump' - 'Version')
println "Bumping ${type.toLowerCase()} version…"
int oldVersionCode = android.defaultConfig.versionCode
String oldVersionName = android.defaultConfig.versionName
version = new Version(oldVersionCode, oldVersionName)
version."bump$type"()
String newVersionName = version.getName()
String newVersionCode = version.getCode()
println "$oldVersionName ($oldVersionCode) → $newVersionName ($newVersionCode)"
def updated = buildFile.getText()
updated = updated.replaceFirst("versionName '$oldVersionName'", "versionName '$newVersionName'")
updated = updated.replaceFirst("versionCode $oldVersionCode", "versionCode $newVersionCode")
buildFile.setText(updated)
}
}
}
}
See this Kanji learning Android app for completeness.
Following format required (note the single quotes):
android {
defaultConfig {
versionCode 3
versionName '0.3.13'
}
}
$ ./gradlew bumpPatchVersion
> Task :app:bumpPatchVersion
Bumping patch version…
0.3.13 (3) → 0.3.14 (4)
BUILD SUCCESSFUL in 0s
1 actionable task: 1 executed
$ ./gradlew bumpMinorVersion
> Task :app:bumpMinorVersion
Bumping minor version…
0.3.14 (4) → 0.4.0 (5)
BUILD SUCCESSFUL in 0s
1 actionable task: 1 executed
$ ./gradlew bumpMajorVersion
> Task :app:bumpMajorVersion
Bumping major version…
0.4.0 (5) → 1.0.0 (6)

Here is an example task:
version='1.0.0' //version we need to change
task increment<<{
def v=buildFile.getText().find(version) //get this build file's text and extract the version value
String minor=v.substring(v.lastIndexOf('.')+1) //get last digit
int m=minor.toInteger()+1 //increment
String major=v.substring(0,v.length()-1) //get the beginning
//println m
String s=buildFile.getText().replaceFirst("version='$version'","version='"+major+m+"'")
//println s
buildFile.setText(s) //replace the build file's text
}
Run this task several times and you should see the version change.
A variant:
version='1.0.0'
task incrementVersion<<{
String minor=version.substring(version.lastIndexOf('.')+1)
int m=minor.toInteger()+1
String major=version.substring(0,version.length()-1)
String s=buildFile.getText().replaceFirst("version='$version'","version='"+major+m+"'")
buildFile.setText(s)
}
You could also use split with a increment-matrix, that could be changed depending on the amount of changes:
def version = '1.0.0'
def incstep = '0.0.1'.split(/\./).collect{it.toInteger()}
def indexedVersionList = version.split(/\./).toList().withIndex()
def updatedVersionList = indexedVersionList.collect{num, idx -> num.toInteger()+incstep[idx]}
def updatedVersion = updatedVersionList.join(".")
This is how I did it with Kotlin DSL (build.gradle.kts):
tasks.create("incrementVersion") {
group = "my tasks"
description = "Increments the version in this build file everywhere it is used."
fun generateVersion(): String {
val updateMode = properties["mode"] ?: "minor" // By default, update the minor
val (oldMajor, oldMinor, oldPatch) = version.split(".").map(String::toInt)
var (newMajor, newMinor, newPatch) = arrayOf(oldMajor, oldMinor, 0)
when (updateMode) {
"major" -> newMajor = (oldMajor + 1).also { newMinor = 0 }
"minor" -> newMinor = oldMinor + 1
else -> newPatch = oldPatch + 1
}
return "$newMajor.$newMinor.$newPatch"
}
doLast {
val newVersion = properties["overrideVersion"] as String? ?: generateVersion()
val oldContent = buildFile.readText()
val newContent = oldContent.replace("""= "$version"""", """= "$newVersion"""")
buildFile.writeText(newContent)
}
}
Usage:
./gradlew incrementVersion [-P[mode=major|minor|patch]|[overrideVersion=x]]
Examples:
./gradlew incrementVersion -Pmode=minor
./gradlew incrementVersion -PoverrideVersion=2.5.11
That is given that you have something like this in your build script:
version = "1.2.3"
... and the patch part of the version is just a number (not containing letters like alpha, rc, etc.).
Below solution will not create an issue evern last number exceed from 9-10 and so on
version='1.0.11.1001'
task incrementrevsion{
def v = version
println v
String minor=v.substring(v.lastIndexOf('.')+1) //get last digit
int m=minor.toInteger()+1 //increment
println m
String major=v.substring(0,v.lastIndexOf(".")); //get the beginning
println major
String s=buildFile.getText().replaceFirst("version='$version'","version='"+major+ "." +m+"'")
//println s
buildFile.setText(s) //replace the build file's text
}
def patch = version.substring(version.lastIndexOf('.') + 1)
def p = patch.toInteger() + 1
def major = version.substring(0, version.length() - p.toString().length())
def s = buildFile.getText().replaceFirst("version = '$version'", "version = '" + major + p + "'")
buildFile.setText(s)
The only difference with Alexiy's answer that line 3 contains m.toString().length() as if minor version > 10, i.e 1.0.12 and you will use that approach it will change it to 1.0.113. We need to calculate the length of minor version instead of chopping off only 1 symbol.
And one more thing, usually the last number is called patch, minor is a middle one :)
My Solution where the version will be set by a Parameter.
version = '4.0.0' // I have whitespaces between the equals-sign
task setVersion << {
group = 'Versioning'
description = "Sets the version to the new number specified with -PnewVersion=\'x.x.x\'"
println version
if(project.hasProperty('newVersion')) {
println 'Set Project to new Version '+newVersion
String s=buildFile.getText().replaceFirst("version = '$version'","version = '"+newVersion+"'")
buildFile.setText(s)
}
}
Call Gradle Task with:
gradle setVersion -PnewVersion='5.1.1'
As for me work this solution. You need add this code into build.gradle file:
version='1.0.1'
tasks.register("incrementVersion") {
doLast {
def ver = version
println ver
String lastNumber = ver.substring(ver.lastIndexOf('.') + 1)
int increment = lastNumber.toInteger() + 1
println increment
String firstNumber = ver.substring(0, ver.lastIndexOf("."))
println firstNumber
String result = buildFile.getText().replaceFirst("version='$version'","version='" + firstNumber + "." + increment + "'")
buildFile.setText(result)
}
}
I know I am posting this quite late, but the answers mentioned above work well upto '1.0.99'. After which it starts misbehaving.
If any one is still interested, I found a different approach.
task increment {
def v = buildFile.getText().find(version)
def (major, minor, patch) = v.tokenize('.')
int newPatch = patch.toInteger() + 1
String newVersion = major + "." + minor + "." + newPatch
String updatedVersion = buildFile.getText().replaceFirst("version='"+v+"'","version='"+newVersion+"'")
buildFile.setText(updatedVersion)
}
This is an example of same think but with KTS(Kotlin Script).
val newVersion: String? by project
tasks.register("bumpVersion") {
this.doFirst {
println("Old version $version")
val newVersion = takeIf { newVersion.isNullOrBlank() }?.let {
val versionArray = version.toString().split(".")
"${versionArray[0]}.${versionArray[1]}.${versionArray.last().toInt().plus(1)}"
} ?: newVersion
buildFile.readText().apply {
println("Bump to $newVersion")
val content = this.replaceFirst("version = \"$version\"", "version = \"$newVersion\"")
buildFile.writeText(content)
}
}
}
Increment automatic the patch or it is possible to send new version as property.
./gradlew bumpVersion -PnewVersion=0.2.0
Kotlin dsl:
tasks.create("incrementPatch") {
group = "version"
description = "Автоматически поднять патч версию в файле VERSION"
doFirst {
incrementVersion("patch")
}
}
tasks.create("incrementMinor") {
group = "version"
description = "Автоматически поднять минор версию в файле VERSION"
doFirst {
incrementVersion("minor")
}
}
tasks.create("incrementMajor") {
group = "version"
description = "Автоматически поднять мажор версию в файле VERSION"
doFirst {
incrementVersion("major")
}
}
tasks.named("compileKotlin") {
dependsOn(":incrementPatch")
}
fun incrementVersion(updateMode: String){
val versions = file("version").readText().trim()
println("read version = $versions")
val (oldMajor, oldMinor, oldPatch) = versions.substringBefore("-").split(".").map(String::toInt)
var (newMajor, newMinor, newPatch) = arrayOf(oldMajor, oldMinor, 0)
when (updateMode) {
"major" -> newMajor = (oldMajor + 1).also { newMinor = 0 }
"minor" -> newMinor = oldMinor + 1
else -> newPatch = oldPatch + 1
}
val newVersion ="$newMajor.$newMinor.$newPatch-SNAPSHOT"
println("new version = $newVersion")
file("version").writeText(newVersion)
}
