java.lang.ClassNotFoundException: org.postgresql.Driver from jooq code generating task

I am implementing java-spring-boot project ( jdk11, spring boot 2.3.0.RELEASE ) using jooq-hikari-hibernate-postgres for back end.
I have already created the tables using flyway.
I have created a task name "generateJooqRepo" in build.gradle to generate the java code for the repository. The task is running however failing with error message:
Execution failed for task ':generateJooqRepo'.
> java.lang.ClassNotFoundException: org.postgresql.Driver
Any insight on what I am doing wrong?

You should add postgres driver dependency to jooqRuntime configuration as well

UPDATE:
You should add postgres driver to your buildscript classpath if you want to use it in gradle script outside of the tasks provided by nu.studer.jooq plugin

Querydsl Annotation Processor issue after upgrade to Gradle 5

I have a gradle script which generates querydsl classes from Mongo annotated entities. It was working so far, but after upgrade to Gradle 5 I have a problem with:
* What went wrong:
Execution failed for task ':myproject-common:compileQuerydsl'.
Annotation processor 'org.springframework.data.mongodb.repository.support.MongoAnnotationProcessor' not found
Please find my gradle.build script below. Any ideas what could be wrong? I read that there was change in Gradle 5 that annotation processors are not used by default during compilation and annotationProcessor declaration should be added but when I add it to dependencies the same error occurs.
plugins {
id 'org.springframework.boot' version '2.0.4.RELEASE'

testCompile("org.assertj:assertj-core:3.7.0")
}

This is my working configuration for JPA without using additional plugins. Gradle 5.3, openjdk 11.0.2.
plugins {
id 'java-library'
}
ext {
springBootVersion = '2.2.0.M1'
queryDslVersion = '4.2.1'
}
dependencies {
api(
"com.querydsl:querydsl-jpa:$queryDslVersion"
)
implementation(
platform("org.springframework.boot:spring-boot-dependencies:$springBootVersion"),
'org.springframework.boot:spring-boot-starter-validation',
'org.springframework.boot:spring-boot-starter-data-jpa',
'org.liquibase:liquibase-core',
'org.postgresql:postgresql'
)
annotationProcessor(
platform("org.springframework.boot:spring-boot-dependencies:$springBootVersion"),
'jakarta.persistence:jakarta.persistence-api',
'jakarta.annotation:jakarta.annotation-api',
"com.querydsl:querydsl-apt:$queryDslVersion:jpa"
)
}
Please pay attention to the annotation processor. It has suffix ":jpa". Probably this is what you missed. To activate the same one for mongodb you should add ":morphia" suffix.
Please also look at these 2 dependencies:
'jakarta.persistence:jakarta.persistence-api'
'jakarta.annotation:jakarta.annotation-api'
This is a workaround for the issue described here:
https://discuss.gradle.org/t/annotationprocessor-querydsl-java-lang-noclassdeffounderror/27107
They should be transitive dependencies of the annotation processor, but they aren't yet. Probably you will have to include some mongo dependencies to annotationProcessor too.
Generated sources are located in \build\generated\sources\annotationProcessor\java\main

I have finally found a workaround. Querydsl's lack of compatibility with Gradle 5 is reported here as a bug: https://github.com/ewerk/gradle-plugins/issues/108
Workaround is to add to gradle script:
compileQuerydsl {
options.annotationProcessorPath = configurations.querydsl
}

I could solve the problem by adding the following two dependencies.
annotationProcessor "com.querydsl:querydsl-apt:4.2.1:jpa"
annotationProcessor 'javax.annotation:javax.annotation-api:1.3.1'
The second dependency was a hidden reason why it not worked for me.

I faced the same issue for Spring Boot Data JPA and Query DSL with Gradle 6.6.1. I tried so many things in my build.gradle file, including some of the suggestions in other responses to this question. I was able to come up with a build.gradle file with a minimal set of additions to the standard build file (standard in the sense of the one generated by https://start.spring.io). Here it is:
plugins {
id 'org.springframework.boot' version '2.4.0'
id 'io.spring.dependency-management' version '1.0.10.RELEASE'
id 'java'
id 'com.ewerk.gradle.plugins.querydsl' version "1.0.10"
}
group = 'org.code'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
querydsl {
querydslDefault = true
jpa = true
}
configurations {
querydsl.extendsFrom implementation
}
compileQuerydsl {
options.annotationProcessorPath = configurations.querydsl
}
ext {
queryDslVersion = '4.4.0'
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation "com.querydsl:querydsl-jpa:${queryDslVersion}"
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
test {
useJUnitPlatform()
}
The key addition is the Query DSL plugin:
id 'com.ewerk.gradle.plugins.querydsl' version "1.0.10"
However, it is not enough on its own. Other important additions are:
querydsl {
querydslDefault = true
jpa = true
}
configurations {
querydsl.extendsFrom implementation
}
compileQuerydsl {
options.annotationProcessorPath = configurations.querydsl
}

The configuration i am using,it works:
plugins {
id 'org.springframework.boot' version '2.2.5.RELEASE'
id 'io.spring.dependency-management' version '1.0.9.RELEASE'
id 'java'
id "com.ewerk.gradle.plugins.querydsl" version "1.0.10"
}
group = 'io.loremipsum'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
querydsl {
library = 'com.querydsl:querydsl-apt:4.1.4'
querydslSourcesDir = 'src/main/querydsl'
springDataMongo = true
}
sourceSets {
main {
java {
srcDirs = ['src/main/java', 'src/main/querydsl']
}
}
}
// is required when gradle > 5.0
compileQuerydsl {
options.annotationProcessorPath = configurations.querydsl
}
dependencies {
compile 'org.springframework.boot:spring-boot-starter-data-mongodb'
compile 'org.springframework.boot:spring-boot-starter-web'
compile("com.querydsl:querydsl-core:4.1.4")
compile("com.querydsl:querydsl-mongodb:4.1.4")
compile("com.querydsl:querydsl-apt:4.1.4")
compile 'org.projectlombok:lombok'
annotationProcessor 'org.projectlombok:lombok'
testCompile('org.springframework.boot:spring-boot-starter-test')
testCompile 'de.flapdoodle.embed:de.flapdoodle.embed.mongo'
}
pay attention to the dependency declaration：
compile 'org.springframework.boot:spring-boot-starter-data-mongodb'
implementation dependency should not be used or will result in an exception:
Annotation processor 'org.springframework.data.mongodb.repository.support.MongoAnnotationProcessor' not found

I see you have compile("com.querydsl:querydsl-apt:4.1.4") in your dependencies. According to the docs
Since implementation details matter for annotation processors, they must be declared separately on the annotation processor path. Gradle ignores annotation processors on the compile classpath.
So, put com.querydsl:querydsl-apt:4.1.4 in the annotationProcessor scope.
BTW, consider switching to api / implementation scopes over compile.

using springboot with local elastic-search instance not working

I want to use elasticSearch repository inside a spring boot application .
I have a local running instance of elastic search 5.5.2
I've search for a while, tried so many combinations of the several sources but nothing yield a working solution , and right now I'm stuck with error :
Error creating bean with name 'elasticsearchTemplate'

what is the proper way of configuration ? some examples shows application.properties configuration , some dont .
What about compatability , some shows that only elasticsearch 2. * or lower, some said that 5
Its really confusing :(
Thank you very much for your help

To use Elasticsearch 5.x you need Spring Data release Kay (already released), which is only part of Spring Boot 2 (to be released soon). Right now your only option really is to use the latest Spring Boot 2 build and wait for a stable release.
Some people tried using Spring Data Kay with Spring boot 1.5, but ended up in dependency hell. Probably not worth the pain with Spring Boot 2 just around the corner.

Add provided dependency to test classpath using Gradle

I've provided dependency scope configured like below. My problem is, the provided dependencies are not visible during runtime in tests. How can I configure this to keep the dependencies provided but available on the test classpath?
apply plugin: 'java'
configurations {
provided
}
sourceSets {
main {
compileClasspath += configurations.provided
}
}
dependencies {
provided 'com.google.guava:guava:18.0'
provided 'org.apache.commons:commons-lang3:3.3.2'
// Tests
testCompile 'junit:junit:4.11'
testCompile 'org.assertj:assertj-core:1.7.0'
// Additional test compile dependencies
testCompile 'joda-time:joda-time:2.2'
}
One solution is to add the dependency like the joda-time library with testCompile scope, but I don't want to duplicate any entries. I'm sure it can be achieved with proper configuration.

Two ways to do this. First, have the testRuntime configuration extend from provided.
configurations {
provided
testRuntime.extendsFrom(provided)
}
Second, you could add the provided configuration to the classpath of your test task.
test {
classpath += configurations.provided
}

Fixed with one additional line in configurations. Don't know if it's the best and a proper solution but works as intended.
configurations {
provided
testCompile.extendsFrom(provided)
}

my case
withType<Jar> {
enabled = true
isZip64 = true
duplicatesStrategy = DuplicatesStrategy.EXCLUDE
archiveFileName.set("$project.jar")
from(sourceSets.main.get().output)
dependsOn(configurations.compileClasspath)
from({
configurations.compileClasspath.get().filter {
it.name.endsWith("jar")
}.map { zipTree(it) }
}) {
exclude("META-INF/*.RSA", "META-INF/*.SF", "META-INF/*.DSA")
}
}

Is there a way to specify dependencies for a newly created sourceset in gradle?

In gradle I have created a new sourceSet for service testing like this:
sourceSets{
servicetest{
java.srcDirs = [//path to servicetests]
}
}
This source set depends on TestNG, so I was hoping to pull the dependency down by doing something like:
dependencies{
servicetest(group: 'org.testng', name: 'testng', version: '5.8', classifier: 'jdk15')
}
Unfortunately this returns an error. Is there any way to declare a dependency for a specific sourceSet or am I out of luck?

Recent Gradle versions automatically create and wire configurations 'fooCompile' and 'fooRuntime' for each source set 'foo'.
If you are still using an older version, you can declare your own configuration and add it to the source set's compileClasspath or runtimeClasspath. Something like:
configurations {
serviceTestCompile
}
sourceSets {
serviceTest {
compileClasspath = configurations.serviceTestCompile
}
}
dependencies {
serviceTestCompile "org.testng:testng:5.8"
}

The following works for Gradle 1.4.
apply plugin: 'java'
sourceCompatibility = JavaVersion.VERSION_1_6
sourceSets {
serviceTest {
java {
srcDir 'src/servicetest/java'
}
resources {
srcDir 'src/servicetest/resources'
}
compileClasspath += sourceSets.main.runtimeClasspath
}
}
dependencies {
compile(group: 'org.springframework', name: 'spring', version: '3.0.7')
serviceTestCompile(group: 'org.springframework', name: 'spring-test', version: '3.0.7.RELEASE')
serviceTestCompile(group: 'org.testng', name:'testng', version:'6.8.5')
}
task serviceTest(type: Test) {
description = "Runs TestNG Service Tests"
group = "Verification"
useTestNG()
testClassesDir = sourceSets.serviceTest.output.classesDir
classpath += sourceSets.serviceTest.runtimeClasspath
}
