We're creating a POM file like so:
task createPom {
doLast {
pom {
project {
groupId project.group
artifactId project.name
version project.ext.pomVersion
}
}.writeTo("${buildDir}/pom.xml")
}
}
This writeTo eagerly writes to the file even if no changes have occurred, which causes the jar to change, so later expensive tasks in the build (indexing, signing, building installers) all have to run as well.
I thought about writing to a temp file and diffing the two files somehow, but it seems like I'd have to write a lot of boilerplate just to do that, so I'm wondering whether there is a proper way to go about it.
What you need to do is to configure task's inputs and outputs which are used to determine whether your task is up-to-date or not. Here, how it should be done:
apply plugin: 'maven'
ext {
pomVersion = '3.1.4.5'
}
group = 'lolgroup'
task createPom {
outputs.file "${buildDir}/pom.xml"
inputs.property('group', project.group)
inputs.property('name', project.name)
inputs.property('pomVersion', project.ext.pomVersion)
doLast {
pom {
project {
groupId inputs.properties['group']
artifactId inputs.properties['name']
version inputs.properties['pomVersion']
}
}.writeTo("${buildDir}/pom.xml")
}
}
Here you can find a demo.

I'm trying to use gradle with proguard to obfuscate the code then generate a zip file to distribute. I'd like to use the distribution plugin, but it always includes the jar that is generated by the jar task. Is there some way to force the distribution plugin to omit the original (non-obfuscated) jar and only include the obfuscated jar? I can easily add the obfuscated jar in addition to the original, but I want to distribute the obfuscated jar instead of the original so the generated execution scripts run against the obfuscated version.
Here's my abridged build.gradle file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'net.sf.proguard:proguard-gradle:5.3.3'
}
}
apply plugin: 'java'
apply plugin: 'application'
task obfuscate(type: proguard.gradle.ProGuardTask) {
configuration 'proguard.txt'
injars "build/libs/${rootProject.name}.jar"
outjars "build/libs/${rootProject.name}-release.jar"
}
jar.finalizedBy(project.tasks.obfuscate)
distributions {
main {
contents {
from(obfuscate) {
into "lib"
}
from(jar) {
exclude "*.jar"
}
}
}
}
I've tried a number of things in the distributions block to try to exclude the original jar, but nothing seems to work.
Any ideas would be greatly appreciated.
This isn't the best solution, but I was able to work around the issue by renaming the jars at the end of the obfuscation step. Now, I name the original jar something like <JAR_NAME>-original.jar and I give the obfuscated jar the original jar's name. I still wish there was a better way to do it, but this seems to work.
Here is the updated, abridged build.gradle file:
import java.nio.file.Paths
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'net.sf.proguard:proguard-gradle:5.3.3'
}
}
apply plugin: 'java'
apply plugin: 'application'
def jarNameWithoutExtension = jar.archiveName.with { it.take(it.lastIndexOf(".")) }
def obfuscatedJarName = "${jarNameWithoutExtension}-release.jar"
def jarFileLocation = jar.archivePath.parent
def obfuscatedFilePath = Paths.get(jarFileLocation, obfuscatedJarName)
task obfuscate(type: proguard.gradle.ProGuardTask) {
configuration 'proguard.txt'
injars jar.archivePath
outjars obfuscatedFilePath.toString()
// Rename the original and obfuscated jars. We want the obfuscated jar to
// have the original jar's name so it will get included in the distributable
// package (generated by installDist / distZip / distTar / assembleDist).
doLast {
jar.archivePath.renameTo(Paths.get(jarFileLocation, "$jarNameWithoutExtension-original.jar").toFile())
obfuscatedFilePath.toFile().renameTo(jar.archivePath)
}
}
jar.finalizedBy(project.tasks.obfuscate)
I wrote a gradle script where I am creating the zip and war file and then I need to upload/publish it to the artifactory but the issue is I specified the war file in my artifact task even after that it is publishing everything to the artifactory zip,tar and war instead of only war file.
apply plugin: 'war'
apply plugin: 'java'
apply plugin: 'distribution'
//-- set the group for publishing
group = 'com.xxx.discovery'
/**
* Initializing GAVC settings
*/
def buildProperties = new Properties()
file("version.properties").withInputStream {
stream -> buildProperties.load(stream)
}
//add the jenkins build version to the version
def env = System.getenv()
if (env["BUILD_NUMBER"]) buildProperties.coveryadBuildVersion += "_${env["BUILD_NUMBER"]}"
version = buildProperties.coveryadBuildVersion
println "${version}"
//name is set in the settings.gradle file
group = "com.aaa.covery"
version = buildProperties.discoveryadBuildVersion
println "Building ${project.group}:${project.name}:${project.version}"
repositories {
maven {
url "http://cxxxxt.tshaaaaa.tho.com:9000/artifactory/libselease"
}
maven {
url "http://cxxxxt.tshaaa.tho.com:9000/artifactory/cache"
}
}
dependencies {
compile ([
"com.uters.omni:HermesSessionAPI:1.2",
"com.uters.proxy:ProxyResources:1.1",
"com.uters.omni:SeshataDirectory:1.0.1" ,
"com.euters.omni:CybeleInfrastructure:1.1.2",
"com.euters:JSONBus:1.4.1",
"javaee:javaee-api:5"
])
}
distributions {
main {
contents {
from {
war.outputs
}
}
}
}
// for publishing to artifactory
artifacts {
archives war
}
According to gradle distribution plugin documentation:
All of the files in the “src/$distribution.name/dist” directory will automatically be included in the distribution.
And also,
The distribution plugin adds the distribution archives as candidate for default publishing artifacts.
In other words, by default all the files will be published so this explains the behavior you're experiencing.
What you can probably do in order to workaround this behavior is to define the contents copySpec more accurately by explicitly exclude the unwanted files, i.e.:
distributions {
main {
contents {
exclude('**/.zip')
exclude('**/.tar')
from {
war.outputs
}
}
}
}
Note that I didn't try the above by myself though so some fine tuning might be needed. However I believe that you can find the data you need in the CopySpec Interface documentation
I'm facing behavior that I can't explain, using gradle 1.10 I have:
settings.gradle:
include('lib1', 'lib2', 'web')
build.gradle:
subprojects {
apply plugin: 'java'
}
project(':web') {
apply plugin: 'war'
dependencies {
compile project(':lib1')
}
task myTask(type: JavaExec, dependsOn: 'compileJava') {
main = "some.thirdparty.Class"
args "--searchPath", configurations.runtime.asPath
}
}
project(':lib1') {
dependencies {
compile project(':lib2')
}
}
project(':lib2') {
}
When I run gradle clean war I only have lib1.jar in war/build/libs/web.war/WEB-INF/lib.
To make WEB-INF/lib contain both lib1.jar and lib2.jar I have to:
move project('web') block to the end of the file
update configurations.runtime.asPath to configurations.runtime (but I need to provide class path as a path, so it is not a solution)
I read the build lifecycle description, tried to compare --debug outputs but that didn't help.
Why is this happening? And what would be a good solution to provide the module runtime class path as a path in JavaExec task please?
asPath resolves the configuration, but resolution will only work correctly if it happens at execution time rather than configuration time (in particular in the presence of project dependencies). Try to wrap the args line with doFirst { ... }.
I am trying to use the avro-gradle-plugin on github, but have not gotten any luck getting it to work. Does anyone have any sample code on how they get it to work?
I figured out how to do it myself. The following is a snippet that I would like to share for people who might run into the same issues as I did:
apply plugin: 'java'
apply plugin: 'avro-gradle-plugin'
sourceCompatibility = "1.6"
targetCompatibility = "1.6"
buildscript {
repositories {
maven {
// your maven repo information here
}
}
dependencies {
classpath 'org.apache.maven:maven-artifact:2.2.1'
classpath 'org.apache.avro:avro-compiler:1.7.1'
classpath 'org.apache.avro.gradle:avro-gradle-plugin:1.7.1'
}
}
compileAvro.source = 'src/main/avro'
compileAvro.destinationDir = file("$buildDir/generated-sources/avro")
sourceSets {
main {
java {
srcDir compileAvro.destinationDir
}
}
}
dependencies {
compileAvro
}
I found "com.commercehub.gradle.plugin.avro" gradle plugin to work better.
use the folllowing:
// Gradle 2.1 and later
plugins {
id "com.commercehub.gradle.plugin.avro" version "VERSION"
}
// Earlier versions of Gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath "com.commercehub.gradle.plugin:gradle-avro-plugin:VERSION"
}
}
apply plugin: "com.commercehub.gradle.plugin.avro"
more details at https://github.com/commercehub-oss/gradle-avro-plugin
When evaluating a plugin the following questions needs to be asked:
Are generated files included into source jar?
Is plugin fast? Good plugin use avro tools api instead of forking VM for every file. For large amount of files creating VM for every file can take 10min to compile.
Do you need intermediate avsc files?
Is build incremental (i.e. do not regenerate all files unless one of the sources changed)?
Is plugin flexible enough to give access to generated schema files, so further actions, such as registration schema in schema repository can be made?
It is easy enough to implement without any plugin if you are not happy with plugin or need more flexibility.
//
// define source and destination
//
def avdlFiles = fileTree('src/Schemas').include('**/*.avdl')
// Do NOT generate into $buildDir, because IntelliJ will ignore files in
// this location and will show errors in source code
def generatedJavaDir = "generated/avro/java"
sourceSets.main.java.srcDir generatedJavaDir
//
// Make avro-tools available to the build script
//
buildscript {
dependencies {
classpath group:'org.apache.avro', name:'avro-tools' ,version: avro_version
}
}
//
// Define task's input and output, compile idl to schema and schema to java
//
task buildAvroDtos(){
group = "build"
inputs.files avdlFiles
outputs.dir generatedJavaDir
doLast{
avdlFiles.each { avdlFile ->
def parser = new org.apache.avro.compiler.idl.Idl(avdlFile)
parser.CompilationUnit().getTypes().each { schema ->
def compiler = new org.apache.avro.compiler.specific.SpecificCompiler(schema)
compiler.compileToDestination(avdlFile, new File(generatedJavaDir))
}
}
}
}
//
// Publish source jar, including generated files
//
task sourceJar(type: Jar, dependsOn: buildAvroDtos) {
from sourceSets.main.allSource
// Package schemas into source jar
into("Schemas") { from avdlFiles }
}
// Clean "generated" folder upon "clean" task
clean {
delete('generated')
}
Configuration for avro with gradle as build tool need to add along with applying java plugin.
below changes in settings.gradle
pluginManagement {
repositories {
gradlePluginPortal()
mavenCentral()
}
}
below changes in build.gradle
plugins {
id "com.github.davidmc24.gradle.plugin.avro" version "1.3.0"
}
repositories {
mavenCentral()
}
dependencies {
implementation "org.apache.avro:avro:1.11.0"
}
generateAvroJava {
source("${projectDir}/src/main/resources/avro")//sourcepath avrofile
}
if you want to generate setter methods too add this task too in build.gradle
avro {
createSetters = true
}

I am new to gradle but learning quickly. I need to get some specific JARs from logback into a new directory in my release task. The dependencies are resolving OK, but I can't figure out how, in the release task, to extract just logback-core-1.0.6.jar and logback-access-1.0.6.jar into a directory called 'lib/ext'. Here are the relevant excerpts from my build.gradle.
dependencies {
...
compile 'org.slf4j:slf4j-api:1.6.4'
compile 'ch.qos.logback:logback-core:1.0.6'
compile 'ch.qos.logback:logback-classic:1.0.6'
runtime 'ch.qos.logback:logback-access:1.0.6'
...
}
...
task release(type: Tar, dependsOn: war) {
extension = "tar.gz"
classifier = project.classifier
compression = Compression.GZIP
into('lib') {
from configurations.release.files
from configurations.providedCompile.files
}
into('lib/ext') {
// TODO: Right here I want to extract just logback-core-1.0.6.jar and logback-access-1.0.6.jar
}
...
}
How do I iterated over the dependencies to locate those specific files and drop them in the lib/ext directory created by into('lib/ext')?
Configurations are just (lazy) collections. You can iterate over them, filter them, etc. Note that you typically only want to do this in the execution phase of the build, not in the configuration phase. The code below achieves this by using the lazy FileCollection.filter() method. Another approach would have been to pass a closure to the Tar.from() method.
task release(type: Tar, dependsOn: war) {
...
into('lib/ext') {
from findJar('logback-core')
from findJar('logback-access')
}
}
def findJar(prefix) {
configurations.runtime.filter { it.name.startsWith(prefix) }
}
It is worth nothing that the accepted answer filters the Configuration as a FileCollection so within the collection you can only access the attributes of a file. If you want to filter on the dependency itself (on group, name, or version) rather than its filename in the cache then you can use something like:
task copyToLib(type: Copy) {
from findJarsByGroup(configurations.compile, 'org.apache.avro')
into "$buildSrc/lib"
}
def findJarsByGroup(Configuration config, groupName) {
configurations.compile.files { it.group.equals(groupName) }
}
files takes a dependencySpecClosure which is just a filter function on a Dependency, see: https://gradle.org/docs/current/javadoc/org/gradle/api/artifacts/Dependency.html
