I am trying to use gradle for this project https://redis.io/docs/stack/get-started/tutorials/stack-spring/. My build.gradle is this one:
plugins {
id 'java'
id 'org.springframework.boot' version '3.0.2'
id 'io.spring.dependency-management' version '1.1.0'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'
configurations {
compileOnly {

}
}
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
implementation "com.redis.om:redis-om-spring:0.6.4"
implementation "io.springfox:springfox-boot-starter:3.0.0"
implementation "io.springfox:springfox-swagger-ui:3.0.0"
}
test {
useJUnitPlatform()
}
I am getting the following err while build this project:
error: cannot find symbol
import com.redis.om.skeleton.models.Person$;
It seems META model classes are not being generated by gradle. I am using Intellij Community edition with java 17.
Any help would be appreciate.
I had to add the following to my build.gradle and it solved my issue:
annotationProcessor("com.redis.om:redis-om-spring:0.6.4")
There is springboot application with gradle and try to convert one object to another using MapStruct, but there is exception in compile time
I added sctruct dependencies in build.gradle by instruction in bottom

tasks.named('test') {

}
tasks.withType(JavaCompile) {

]
}
My interface look like this
#Mapper
public interface DeviceAgentMessageMapper {
#Mapping(source = "gamma", target = "message")
AgentMessage toAgentMessage(Device device);
}
But when try to start application or call build gradle job, there is error message:
The following options were not recognized by any processor: '[mapstruct.suppressGeneratorTimestamp]'

When I try to compile the child project I get error:
Execution failed for task ':compileJava'.

Do you know how I can define properly the parent Gradle project with all dependencies versions and use the child project without defining dependencies versions?
There’s a relatively new Gradle feature called “version catalogs”. With those you can centrally declare dependencies that you’d like to share between multiple projects of your build (or even between different builds).
In your concrete example, you’d add something like the following to your settings.gradle file:
dependencyResolutionManagement {
versionCatalogs {
libs {
library('spring-cloud-bom', 'org.springframework.cloud:spring-cloud-dependencies:2021.0.1')
library('spring-cloud-starter', 'org.springframework.cloud', 'spring-cloud-starter-netflix-eureka-client').withoutVersion()
library('spring-boot-starter-validation', 'org.springframework.boot', 'spring-boot-starter-validation').withoutVersion()
library('spring-boot-starter-test', 'org.springframework.boot', 'spring-boot-starter-test').withoutVersion()
library('threetenbp', 'org.threeten:threetenbp:1.5.1')
library('spring-boot-starter-actuator', 'org.springframework.boot', 'spring-boot-starter-actuator').withoutVersion()
library('lombok', 'org.projectlombok:lombok:1.18.22')
library('springfox-boot-starter', 'io.springfox:springfox-boot-starter:3.0.0')
library('spring-boot-starter-hateoas', 'org.springframework.boot:spring-boot-starter-hateoas:2.6.3')
library('hysterix-core', 'com.netflix.hystrix:hystrix-core:1.5.18')
library('spring-security-core', 'org.springframework.security:spring-security-core:5.6.1')
library('junit-jupiter-api', 'org.junit.jupiter:junit-jupiter-api:5.8.2')
library('junit-jupiter-engine', 'org.junit.jupiter:junit-jupiter-engine:5.8.2')
}
}
}
Then, in both build.gradle files, you’d replace your dependencies blocks with the following:
dependencies {
implementation libs.spring.cloud.starter
implementation libs.spring.boot.starter.validation
testImplementation libs.spring.boot.starter.test
implementation libs.threetenbp
implementation libs.spring.boot.starter.actuator
// Lombok
compileOnly libs.lombok
annotationProcessor libs.lombok
testCompileOnly libs.lombok
testAnnotationProcessor libs.lombok
// Swagger
implementation libs.springfox.boot.starter
implementation libs.spring.boot.starter.hateoas
implementation libs.hysterix.core
implementation libs.spring.security.core
testImplementation libs.junit.jupiter.api
testRuntimeOnly libs.junit.jupiter.engine
}
As you’re using a Maven BOM for Spring, you’ll also have to use the following updated dependencyManagement block in all projects:
dependencyManagement {
imports {
mavenBom libs.spring.cloud.bom.get().toString()
}
resolutionStrategy {
cacheDynamicVersionsFor 0, "seconds"
cacheChangingModulesFor 0, "seconds"
}
}
That should be it. I could successfully test your sample build configurations with my updates at least on Gradle 7.4.
I have a "multi-module" Gradle project named "utils". In that, I have created a new sub-project that will be used as a client for Hashicorp's Vault. I'll use this jar to my Spring Boot microservices as a dependency.
The goal is to have a common configuration for Vault and use it in all the services.
My problem is when I try to auto-wire the VaultTemplate object (presuming it will be added from this jar), in one of my Spring Boot microservices (say secrets-management-service), I could not achieve that.
For development purposes, I have included the jar as a local dependency. I have included both the build.gradle files.
External Jar: vault-client

compileOnly 'org.projectlombok:lombok'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
test {
useJUnitPlatform()
}
I found it myself. I had missed the below block in my vault-client jar and also forgot to remove "main" class.
bootJar {
enabled = false
}
Hallo everyone i have one litle problem with my bulid.gradle i will run my project but this ist not possible. Does someone have an idea why this can be ?
I get this error:
Execution failed for task ':compileQuerydsl'.

Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
