Build jar for each main class using gradle - gradle

1.My project has two main class i want to build jar for each main class using gradle. my source has 2 files ValidationRule.java
SupportValidator.java both the file have one main class each i want to
build the jar for each main class
i can achieve the same from eclipse working fine
2.I want to load the source file for my project from 2 different folder,some part is there in one folder and remaining is
there in
another folder i.e like
project/src snd another folder outside the project(../../../SharedClass)
my script as follows
apply plugin: 'eclipse'
apply plugin: 'java'
sourceCompatibility = 1.6
archivesBaseName = 'Process_XY'
configurations {
configurations.compile.transitive = false
}
dependencies {
compile fileTree(dir:'/trunk/Solutions/project/Source/Binaries/CommonFunctions/build/libs', include: '*.jar')

manifest.attributes("Main-Class":"org.project.seismic.Process_XY")
}
sourceSets {
main {
java {
source = ['src/org', '../../../SharedClass/org']
}
}
}
above in sourceSets method i tried to load source from 2 folder but it
didnt worked
Thanks in advance..!!
How to achieve using gradle.

Ok, first of all, the source on a SourceDirectorySet takes another SourceDirectorySet. The srcDirs method however takes paths. Change that block to the following:
sourceSets {
main {
java {
srcDirs ['src/org', '../../../SharedClass/org']
}
}
}
And you can easily add a second jar task as follows:
task secondJar(type: Jar) {
name = other-main-jar
from ...
manifest.attributes(...)
}
assemble.dependsOn(secondJar)
This will register a new Jar task called secondJar and makes sure that when the project is assembled, this jar is also created.

Running PMD with gradle without compiling

I need to integrate PMD into the build process, so I created a file, 'check.gradle' under a separate directory and added it to the build.gradle which is a main file for the build process.
build.gradle
buildscript {
ext {
sbDir = "${projectDir.parent}"
}
repositories {
mavenCentral()
jcenter()
}
}
allprojects {
repositories {
mavenCentral() // maven { url: 'http://jcenter.bintray.com' }
}
}
apply from: file('../build/pmd/check.gradle')
check.gradle
subprojects {
apply plugin: 'pmd'
pmd {
consoleOutput = true
toolVersion = "6.21.0"
reportsDir = file("pmd/reports")
ruleSets = ["../build/pmd/MyRuleSet.xml"]
ignoreFailures = true
}
}
The code base is written in Java. The problem is that I want to run it before compile happens or i don't want to run it separately as a simple task. Our compile task is pretty complicated, cuz it depends on many libraries.
I am running as like this.
gradlew.bat --build-file bundles/build.gradle check
Is there a way to scan all the java source code (we have 200 bundles - each bundle is packaged with many java files) without compiling java source code?

Adding external source files to a kotlin project

I have Kotlin sources located at, say, repo/project_a/src/. I created a Kotlin Gradle project in IntelliJ IDEA, located at repo/project_b/.... And I can't for the life of me figure out how to add the sources. If I add them through project structure menu it works fine, but as soon as it wants to re-read the gradle file id deletes the structure (It warns as much in the UI).
This is my gradle file:
plugins {
id 'org.jetbrains.kotlin.jvm' version '1.2.70'
}
group 'cli'
version '1.0'
repositories {
mavenCentral()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
}
compileKotlin {
kotlinOptions.jvmTarget = "1.8"
}
I've tried adding all variations of
sourceSets {
main {
kotlin {
srcDirs += "repo/project_a/"
}
}
}
But it does absolutely nothing.
Any ideas?
The path you are giving to Gradle will compile to the current project path plus "repo/project_a/". Try with:
sourceSets {
main {
kotlin {
srcDirs += "../project_a/"
}
}
}

How to specify output.classesDir for custom sourceSet in Gradle?

My build uses source code from two projects: ProjectA and ProjectB, and produces JAR with classes and resources from ProjectB. I defined custom sourceSet mainProjectB which is supposed to have output in a separate directory:
sourceSets {
mainProjectB {
output.classesDir = "$buildDir/build/classes/projectB"
output.resourcesDir = "$buildDir/build/resources/projectB"
java { srcDirs = ['src/main/java']}
resources { srcDirs = ['src/main/resources']}
}
mainProjectA {
java { srcDirs = [
'../projectA/src/main/java'
]}
resources { srcDirs = [
'../projectA/src/main/resources'
]}
}
test {
java {
srcDirs = [
'../projectA/src/test/java',
'src/test/java'
]}
resources {
srcDirs = [
'../projectA/src/test/resources',
'src/test/resources'
]}
}
}
compileJava {
source sourceSets.mainProjectB.allJava
source sourceSets.mainProjectA.allJava
}
processResources {
from sourceSets.mainProjectB.resources
from sourceSets.mainProjectA.resources
}
jar {
from sourceSets.mainProjectB.output.classesDir
from sourceSets.mainProjectB.output.resourcesDir
}
Problem: custom sourceSet mainProjectB ingores specified output directories.
The directories "$buildDir/build/classes/projectB" and "$buildDir/build/resources/projectB" are not created, and as a consequence, JAR includes files from both projects (instead of ProjectB).
UPDATE:
Projects A and B have circular dependencies. That is why they have to share source code.
I would consider to use subprojects and project to achieve your goal - gradel docs . With the following approach you can get any kind of jar file depending on your build :
group 'CoreProject'
version '1.0-SNAPSHOT'
subprojects {
apply plugin: 'java'
repositories {
mavenCentral()
}
}
project (':projectA') {
}
project (':projectB') {
def generatedResources = "$buildDir"
//in case you want resources and classes to be written to custom location where
//redefined paths are relative to projectB root folder
sourceSets {
main {
output.classesDir = 'build/classes/projectB'
output.resourcesDir = 'build/resources/projectB'
}
}
dependencies {
compile project(':projectA')
}
jar {
manifest.mainAttributes(
'Main-Class': "ProjectBClass"
)
}
//To create fat Jar that will contain classes and resources from all dependencies
task fatJar(type: Jar) {
manifest.from jar.manifest
classifier = 'all'
from {
configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "ProjectAResource" //if want to exclude resources from projectA
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
}
If you run jar task of projectB following jars will be created, each including only its own classes and resources : projectA/build/libs/projectA.jar , projectB/build/libs/projectB.jar('JAR with classes and resources from ProjectB' as you asked in your comment)
If you run farJar task of projectB the following jar file will be created that includes classes and resources from both projects and you can exclude any files patterns from projectA and projectB projects to create any final jar you like : projectB/build/libs/projectB-all.jar
Here is a screenshot of projects folders structure I created to mimic your scenario(as I understood it):
P.S. Also make sure none of the folders projectB/build and projectA/build are locked by any process and remove those handles if any, as otherwise Gradle will fail to run.

Building a fully executable Spring Boot 1.3 war from a Gradle multi project build

I'm trying to build a fully executable WAR using Spring Boot 1.3 as per https://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html. If I build a single Gradle project, it all works fine, but I havea multi project build, where I have a "root" project and then several projects underneath it, and I cannot get it to build anything but a standard, "fat" WAR file, without the providedRuntime of Jetty and without the scripts to make it run.
Does anyone know how to do this?
In my root project, I have the following (abridged):
buildscript {
repositories {
mavenCentral()
}
ext {
springBootVersion = '1.3.0.RELEASE'
}
dependencies {
classpath "org.springframework.boot:spring-boot-gradle-plugin:$springBootVersion"
}
}
allprojects {
//Put instructions for all projects
repositories {
mavenCentral() // jcenter is missing spring-orm.4.1.6.RELEASE jar file so try mavenCentral first
jcenter {
url "http://jcenter.bintray.com/"
}
maven { url 'http://repo.opensourceagility.com/release' }
}
}
subprojects {
apply plugin: 'java'
apply plugin: 'spring-boot'
}
and then in the subproject which is a web project, and which I'm trying to build, I have:
apply plugin: 'war'
dependencies {
// Include related projects
compile project(':project-model')
compile project(':project-dynamoDB')
// Core Spring Boot - note version is set in main build.gradle file
compile 'org.springframework.boot:spring-boot-starter-web'
// Remove Tomcat (included in -web) and include Jetty instead
providedRuntime 'org.springframework.boot:spring-boot-starter-jetty'
// Other Spring modules
compile 'org.springframework.boot:spring-boot-starter-social-facebook'
compile 'org.springframework.boot:spring-boot-starter-social-linkedin'
compile 'org.springframework.social:spring-social-google:1.0.0.RELEASE'
compile 'org.springframework.boot:spring-boot-starter-thymeleaf'
compile 'org.springframework.boot:spring-boot-starter-security'
compile 'org.springframework.boot:spring-boot-starter-actuator'
compile 'org.springframework.boot:spring-boot-devtools'
compile 'org.springframework:spring-context'
compile 'org.springframework:spring-context-support'
}
configurations {
providedRuntime.exclude group: 'org.springframework.boot', module:'spring-boot-starter-tomcat'
all*.exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging' // exclude when using log4j
}
springBoot {
mainClass = 'rs.web.Weblication'
executable = true
}
bootRun {
addResources = true
}
processResources {
// exclude resources if they look like they're profile dependent but don't match the current env/profile
eachFile { d ->
if(d.name.endsWith('.xml') || d.name.endsWith('.yaml') || d.name.endsWith('.properties')) {
//def fname = d.name.replaceFirst(~/\.[^\.]+$/, '')
//if(fname.indexOf("-") > -1 && ! fname.endsWith("-" + environment)) {
// d.exclude()
//} else {
// replace #variables# listed below in properties/config files
filter(org.apache.tools.ant.filters.ReplaceTokens, tokens: [
activeProfiles: environment
])
//}
}
}
}
war {
baseName = 'project-web'
version = '1.0.0'
manifest {
attributes 'Implementation-Title': baseName,
'Implementation-Version': version
}
webXml = file('src/main/resources/web.xml')
// rename the war task which has profiles appended from warName-profile,profile2.war
// to warName-profile.profile2.war
classifier = environment.replaceAll(',','-')
}
but when I build it (./gradlew build, or ./gradlew subprojectname:build), all is well and a working WAR is created, but not an executable one.
With a single project, I have it working fine.
Ah ha, right well I build a test multi-project build and it worked OK, so it was clearly the configuration above.
I worked through a process of elimination and it turns out that the problematic area was the line
classifier = environment.replaceAll(',','-')
which is intended to rename files with environment variables as part of the name. This process seems to get in the way of the script addition; perhaps it could be applied afterwards if it's really necessary.

avro gradle plugin sample usage

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
}
