I have 3 stages(a,b,c) to run on jenkins using pipeline code(scripted), I
need to run stage a,b in parallel and run c after a is success (I am
doing this using pipeline code) but in blue ocean it showing only task
name but I wanna see stage names(in this case I have only 2 tasks with 3
stages and stage a and c are in one task). can someone help how can view
all three stages according to this situation.
def stages = [failFast: false]
def testList = ["a", "b", "c"]
def tasks = [:]
tasks["a-and-c"] = {
stage ("a"){
ansiColor('xterm') {
sh " ls -lart; sleep 30 "
}
if (currentBuild.currentResult == 'SUCCESS') {
stage("c") {
ansiColor('xterm') {
sh " ls -lart "
}
}
} else {
sh 'exit'
}
}
}
tasks["c"] = {
stage ("c"){
ansiColor('xterm') {
sh " ls -lart; sleep 20"
}
}
}
parallel tasks
I am expecting to have a separate view in blueocean for all three stages,
right now I am getting a-and-c and b parallel but I looking for a,b as
parallel and c after a is success. Thank you in advance.
Gradle 2.14
I write my custom task "run"
task run() {
def allVariantList = [];
android.applicationVariants.all { variant ->
allVariantList.add(variant.getName())
println "Current allVariantList = " + allVariantList
}
println "Result allVariantList = " + allVariantList
}
Start my task: gradlew run
Result:
Result allVariantList = []
Current allVariantList = [prod_no_check]
Current allVariantList = [prod_no_check, prod]
Current allVariantList = [prod_no_check, prod, stage]
Current allVariantList = [prod_no_check, prod, stage, dev]
Current allVariantList = [prod_no_check, prod, stage, dev, release]
Current allVariantList = [prod_no_check, prod, stage, dev, release, dev_no_check]
Questions:
Why println "Result allVariantList = " + allVariantList run BEFORE println "Current allVariantList = " + allVariantList
I need to println "Result allVariantList = " + allVariantList execute AFTER
println "Current allVariantList = " + allVariantList. How I can do this?
I think the problem is, that at the time your task is configured (you do all your stuff at configuration time, not execution time, the applicationVariants are not yet configured by the android plugin. applicationVariants.all runs on all variants that are already added and also on all variants that get added in the future as soon as they are added.
So your output would suggest that at configuration time no variants are setup yet, thus your result printing is empty and the others come later when the variants are created.
As you do everythign you do at configuration time, it will also always be done, even if you don't execute your task. If you call gradlew help or anything else, you will get the same output.
So either do all your code in the execution phase (wrapping it in a doLast { } closure), or at least do the result printing in the execution phase. If you need your stuff to be done before the execution phase and independently whether your task is actually run or not, you might wrap at least your result printing in an afterEvaluate { } closure that gets executed after the project is evaluated, but still in the configuration phase.
OK, thank everybody. This is work:
task run() {
description "Install and run app on device/emulator"
def allVariantList = [];
android.applicationVariants.all { variant ->
allVariantList.add(variant.getName())
println "Current allVariantList = " + allVariantList
}
doLast {
println "Result allVariantList = " + allVariantList
}
}
Here is the explanation.
https://docs.gradle.org/current/userguide/build_lifecycle.html
Example 22.1. Single project build
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 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)
}
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.
Prerequisites
Following format required (note the single quotes):
android {
defaultConfig {
versionCode 3
versionName '0.3.13'
}
}
Usage
$ ./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)
BUILD SUCCESSFUL in 0s
1 actionable task: 1 executed
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 = $newVersion")
file("version").writeText(newVersion)
}
Is there an easy way to concatenate multiple text files into a single one in Gradle? The build script should look something like this:
FileCollection jsDeps = files(
'file1.js',
'file2.js'
// other files here
)
task concatenate << {
// concatenate the files to file.js
}
I am using Gradle 2.3.
leftShift / "<<" is deprecated in gradle 3.4 You may use something like:
task concatenate {
doLast {
def toConcatenate = files("filename1", "filename2", ...)
def outputFileName = "output.txt"
def output = new File(outputFileName)
output.write('') // truncate output if needed
toConcatenate.each { f -> output << f.text }
}
You can also register the files as inputs/outputs to help with incremental builds. It's especially helpful with larger files.
something like this:
task 'concatenateFiles', {
inputs.files( fileTree( "path/to/dir/with/files" ) ).skipWhenEmpty()
outputs.file( "$project.buildDir/tmp/concatinated.js" )
doLast {
outputs.files.singleFile.withOutputStream { out ->
for ( file in inputs.files ) file.withInputStream { out << it << '\n' }
}
}
}
Instead of the fileTree, it can also be replaced with sourceset/sourceset output, specific files, outputs from a different task, etc.
Gradle doc on task inputs/output
Concatenating files in groovy
The following task should do the job:
task concatenate << {
def toConcatenate = files('f1', 'f2', 'f3')
def output = new File('output')
toConcatenate.each { f -> output << f.text }
}
(new File('test.js')).text = file('test1.js').getText() + file('test2.js').getText()
UPDATE:
For collections.
(new File('test.js')).text = files('test1.js', 'test2.js').collect{it.getText()}.join("\n")
I have three gradle Tasks: A, B and B2. They depend on each other in the following way: A <- B <- B2 (meaning B depends on A and B2 depends on B). Here is my code:
task A {
println "Exec A"
}
task B(dependsOn: A) << {
throw new StopExecutionException("skip this task") // this exception prevents the println, but doesn't change the TaskStatus of B
println "Exec B"
}
task B2(dependsOn: B) << {
println "Did work: " + B.getState().getDidWork();
println "Exec: " + B.getState().getExecuted();
println "Failure: " + B.getState().getFailure();
println "Skip message: " + B.getState().getSkipMessage();
println "Skipped: " + B.getState().getSkipped();
println "Exec B2"
}
When I execute this (by running gralde -q B2), I get the following output:
> gralde -q B2
Exec A
Did work: true
Exec: true
Failure: null
Skip message: null
Skipped: false
Exec B2
As can be seen, the properties of the TaskState didn't change although the StopExecutionException was thrown correctly. How can I determine in a task if all former tasks were executed completely?
StopExecutionException is simply a shortcut to finish the task execution. The task doesn't fail if it is thrown as you can read in documentation neither is the task skipped. You can throw GradleException to make the task fail and then the subsequent task will be able to check the result. Note that you will need to change B2 to make it a finalizing task of B (see here) or play with runAfter or something similar.
