I want to compile (with a different targetCompatibility and sourceCompatibility) and jar a small subset of my whole main/src/java folder.
So I have e.g.
main/src/java/com/interface/A.java
main/src/java/com/interface/B.java
main/src/java/com/logic/C.java
I want to compile A and B to a jar "projectname_projectversion_interface.jar" and using a different compiler version.
Is this possible? How can I do this?
Thanks
I recommend to use a separate source set:
apply plugin: "java"
sourceSets {
main {
java {
exclude "com/interface/A.java"
exclude "com/interface/B.java"
}
}
api {
java {
srcDir "src/main/java"
include "com/interface/A.java"
include "com/interface/B.java"
}
}
}
If main depends on api, add something like:
sourceSets.main.compileClasspath += sourceSets.api.output
Source/target compatibility can be adjusted on the compile task level:
compileApiJava {
sourceCompatibility = "1.7"
targetCompatibility = "1.7"
}
To use a compiler other than that belonging to the JDK that Gradle itself is run with, you'll have to set a compiler executable:
compileApiJava {
options.fork = true
options.forkOptions.executable = "/path/to/compiler/executable"
}
This may slow down the build to some extent.
For further API details, check out the Gradle Build Language Reference.

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?
I am fairly new to both Gradle and Swagger code generator plugin for it (concretely the one that is linked from Swagger's website, i.e. https://github.com/thebignet/swagger-codegen-gradle-plugin), so I'm not sure whether my problem is with Gradle in general or with that particular plugin.
I've created a simple multi-module Spring Boot application (but the fact that I'm using Spring Boot or even Spring doesn't matter much). It's a console application; i.e. it doesn't start a webserver. In fact, it's actually a REST client consuming someone else's interface.
The application consists of four modules: spc-parent (which is just an envelope for the rest) containing spc-boot, spc-service, and spc-integration-model. Spc-boot contains just the starting point of the application, spc-service now contains a single Spring service, and spc-integration-model is meant to contain classes needed to consume the REST interface. The resulting structure will be much more complicated but I've tried to create a sort of a minimal example.
The problem lies within the spc-integration-model module. It consists of a single source file, petstore.json, and a build.gradle copied from https://github.com/thebignet/swagger-codegen-gradle-plugin (and only slightly modified). There are actually two problems (but they may have the same underlying cause).
When running gradle build (from spc-parent) for the very first time, it fails. Java sources are generated from petstore.json but they don't get compiled, which is why the service in spc-service doesn't see needed classes. However, running gradle build a second time fixes this (generated Java sources get compiled which makes it possible to compile spc-service, too).
The created JAR of spc-integration-model never contains anything besides Manifest.
My goal here is to persuade Gradle to compile the generated classes right away during the first build and also to put them into the JAR.
Now for some concrete Gradle tasks. The most interesting is spc-integration-model's build.gradle:
plugins {
id 'org.detoeuf.swagger-codegen' version '1.7.4'
id 'java'
}
apply plugin: 'org.detoeuf.swagger-codegen'
repositories {
mavenCentral()
jcenter()
}
swagger {
inputSpec = 'http://petstore.swagger.io/v2/swagger.json'
outputDir = file('build/swagger')
lang = 'java'
additionalProperties = [
'apiPackage' : 'ondra.spc.integration.client.api',
'dateLibrary' : 'java8',
'hideGenerationTimestamp': 'true',
'invokerPackage' : 'ondra.spc.integration.client',
'library' : 'resttemplate',
'modelNameSuffix' : 'Dto',
'modelPackage' : 'ondra.spc.integration.client.model'
]
importMappings = [
'Dog': 'io.swagger.petstore.client.model.Dog'
]
}
sourceSets {
swagger {
java {
srcDir file("${project.buildDir.path}/swagger/src/main/java")
}
}
}
classes.dependsOn('swagger')
ext {
spring_boot_version = springBootVersion
jackson_version = jacksonVersion
junit_version = jUnitVersion
swagger_annotations_version = swaggerAnnotationsVersion
swagger_codegen_version = swaggerCodegenVersion
}
dependencies {
swaggerCompile "org.springframework.boot:spring-boot-starter-web:$spring_boot_version"
swaggerCompile "io.swagger:swagger-annotations:$swagger_annotations_version"
compile sourceSets.swagger.output
compile "com.fasterxml.jackson.core:jackson-core:$jackson_version"
compile "com.fasterxml.jackson.core:jackson-annotations:$jackson_version"
compile "com.fasterxml.jackson.core:jackson-databind:$jackson_version"
compile "io.swagger:swagger-codegen:$swagger_codegen_version"
testCompile "junit:junit:$junit_version"
}
(Now that I'm re-reading my question I see that the local version of petstore.json is actually not used and an online version is used instead but let's leave that aside.)
The rest should be quite straightforward. spc-service:
dependencies {
compile "org.springframework:spring-context:$springVersion"
compile "org.springframework:spring-web:$springVersion"
compile project (":spc-integration-model")
}
spc-boot:
dependencies {
compile "org.springframework.boot:spring-boot:$springBootVersion"
compile "org.springframework.boot:spring-boot-autoconfigure:$springBootVersion"
compile "org.springframework:spring-web:$springVersion"
runtime "org.hibernate.validator:hibernate-validator:$hibernateVersion"
runtime "com.fasterxml.jackson.core:jackson-databind:$jacksonVersion"
compile project (":spc-service")
testCompile("org.junit.jupiter:junit-jupiter-api:$jUnitVersion")
testRuntime("org.junit.jupiter:junit-jupiter-engine:$jUnitVersion")
}
test {
useJUnitPlatform()
}
spc-parent:
subprojects {
apply plugin: 'java'
group 'ondra'
version '1.0-SNAPSHOT'
buildscript {
ext {
hibernateVersion = '6.0.9.Final'
jacksonVersion = '2.9.4'
springBootVersion = '2.0.0.RELEASE'
springVersion = '5.0.5.RELEASE'
swaggerAnnotationsVersion = '1.5.16'
swaggerCodegenVersion = '2.2.3'
jUnitVersion = '5.1.1'
}
repositories {
mavenCentral()
}
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
}
}
And spc-parent's settings.gradle:
rootProject.name = 'spc-parent'
include 'spc-boot'
include 'spc-service'
include 'spc-integration-model'
I've also put the whole application into a single archive: https://drive.google.com/open?id=1cOYIcaxnhik548w0wEGswgD2g4udATdD
I'm trying to build a project that uses both Google protocol buffers and Kotlin using Gradle. I want the proto files to compile into Java source, which is then called from my Kotlin code.
My source files are arranged like this:
src/main/proto/*.proto
src/main/kotlin/*.kt
src/test/kotlin/*.kt
Here's my build.gradle file:
version '1.0-SNAPSHOT'
apply plugin: 'kotlin'
apply plugin: 'java'
apply plugin: 'com.google.protobuf'
repositories {
mavenCentral()
maven { url "http://dl.bintray.com/kotlin/kotlin-eap-1.1" }
}
buildscript {
ext.kotlin_version = '1.1-M02'
repositories {
mavenCentral()
maven { url "http://dl.bintray.com/kotlin/kotlin-eap-1.1" }
}
dependencies {
classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
protobuf {
protoc {
artifact = 'com.google.protobuf:protoc:3.0.0'
}
}
dependencies {
compile 'com.google.protobuf:protobuf-java:3.0.0'
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
testCompile 'junit:junit:4.12'
}
When I run ./gradlew assemble I get a bunch of "Unresolved reference" errors during :compileKotlin. Afterwards I can see that there are no Java source files generated, so it appears that the proto compiler is not being invoked at all.
If I remove the apply plugin: 'kotlin' line, then ./gradlew assemble successfully generates the Java source, but of course my Kotlin source is never compiled.
How do I fix my build.gradle so that I can call my protobuf code from Kotlin?
To get protobuf-gradle-plugin and kotlin-gradle-plugin to cooperate, you need to ensure that the Java code is (re)generated before invoking the Kotlin compiler.
For Gradle's default source sets, main and test, you can do that like this:
compileKotlin.dependsOn ':generateProto'
compileTestKotlin.dependsOn ':generateTestProto'
If you are using other source sets, you'll need to make adjustments.
Older versions of protobuf-gradle-plugin also required updating sourceSets, but newer versions do not seem to require this.
// Don't do this with protobuf-gradle-plugin 0.9.0 or higher
sourceSets.main.java.srcDirs += "${protobuf.generatedFilesBaseDir}/main/java"
sourceSets.test.java.srcDirs += "${protobuf.generatedFilesBaseDir}/test/java"
For Kotlin and Android:
android {
sourceSets {
debug.java.srcDirs += 'build/generated/source/proto/debug/java'
release.java.srcDirs += 'build/generated/source/proto/release/java'
}
}
An additional source directory has to be added for every build type. In this sample there are two build types: debug and release.
If you're using grpc, another line has to be added per build type:
android {
sourceSets {
debug.java.srcDirs += 'build/generated/source/proto/debug/java'
debug.java.srcDirs += 'build/generated/source/proto/debug/grpc'
release.java.srcDirs += 'build/generated/source/proto/release/java'
release.java.srcDirs += 'build/generated/source/proto/release/grpc'
}
}
At least with Kotlin 1.0.6, protobuf-gradle-plugin 0.8.0, protobuf 3.2.x and grpc 1.x it's not required to fiddle with the task order.
if you are working with multiple build types and flavors in android and with protobuf-lite use below with kotlin.
for example I have debug and release builds with demo and prod flavors it will create demoDebug, demoRelease and prodDebug and prodRelease variants.
then use
`
android{
sourceSets {
debug.java.srcDirs += 'build/generated/source/proto/demoDebug/javalite'
debug.java.srcDirs += 'build/generated/source/proto/prodDebug/javalite'
release.java.srcDirs += 'build/generated/source/proto/demoRelease/javalite'
release.java.srcDirs += 'build/generated/source/proto/prodRelease/javalite'
}
}
`
tie the different compileKotlin with generateProto
tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
if (getName() == 'compileDemoDebugKotlin')
dependsOn(':app:generateDemoDebugProto')
if (getName() == 'compileDemoReleaseKotlin')
dependsOn(':app:generateDemoReleaseProto')
if (getName() == 'compileProdDebugKotlin')
dependsOn(':app:generateProdDebugProto')
if (getName() == 'compileProdReleaseKotlin')
dependsOn(':app:generateProdReleaseProto')
}
For the gradle setup :
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'com.google.protobuf' version "0.8.17"
}
Then at the bottom of the build.gradle
protobuf {
protoc {
artifact = "com.google.protobuf:protoc:3.10.0"
}
// Generates the java Protobuf-lite code for the Protobufs in this project. See
// https://github.com/google/protobuf-gradle-plugin#customizing-protobuf-compilation
// for more information.
generateProtoTasks {
all().each { task ->
task.builtins {
java {
option 'lite'
}
}
}
}
}
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.
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)

apply plugin: 'eclipse'
apply plugin: 'java'

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.
