导入 io.r2dbc.postgresql.codec 时 gradle 出现问题

Question

Every time i try to build or run from gradle (gradle bootRun or./gradlew bootRun), while importing io.r2dbc.postgresql.codec.Json, i get this error:

Stack trace

package com.test.backend;

import io.r2dbc.postgresql.codec.Json;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class BackendApplication {
    public static void main(String[] args) {
        SpringApplication.run(BackendApplication.class, args);
        Json test = Json.of("testing");
        System.out.println(test);
    }
}

Steps to reproduce

plugins {
    id 'org.springframework.boot' version '2.6.7'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.test'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '18'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jdbc'
    implementation 'org.springframework.boot:spring-boot-starter-data-r2dbc'
    implementation 'org.springframework.boot:spring-boot-starter-validation'
    implementation 'org.springframework.boot:spring-boot-starter-webflux'
    compileOnly 'org.projectlombok:lombok'
    runtimeOnly 'io.r2dbc:r2dbc-postgresql'
    runtimeOnly 'org.postgresql:postgresql'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'io.projectreactor:reactor-test'
}

tasks.named('test') {
    useJUnitPlatform()
}

build.gradle:

 plugins { id 'org.springframework.boot' version '2.6.7' id 'io.spring.dependency-management' version '1.0.11.RELEASE' id 'java' } group = 'com.test' version = '0.0.1-SNAPSHOT' sourceCompatibility = '18' configurations { compileOnly { extendsFrom annotationProcessor } } repositories { mavenCentral() } dependencies { implementation 'org.springframework.boot:spring-boot-starter-data-jdbc' implementation 'org.springframework.boot:spring-boot-starter-data-r2dbc' implementation 'org.springframework.boot:spring-boot-starter-validation' implementation 'org.springframework.boot:spring-boot-starter-webflux' compileOnly 'org.projectlombok:lombok' runtimeOnly 'io.r2dbc:r2dbc-postgresql' runtimeOnly 'org.postgresql:postgresql' annotationProcessor 'org.projectlombok:lombok' testImplementation 'org.springframework.boot:spring-boot-starter-test' testImplementation 'io.projectreactor:reactor-test' } tasks.named('test') { useJUnitPlatform() }

Expected behavior/code

When i debug-run the project from the IDE (vscode) it works and prints the Json object.

Answer 1

I solved it by changing the build.gradle to:

implementation 'io.r2dbc:r2dbc-postgresql'

Answer 2

It must be versioning problems, I tried this and it is solved:

implementation 'org.postgresql:r2dbc-postgresql'
