找不到spring-boot-2.3.0.build-snapshot.jar错误

Question

无法解析配置“：classpath”的所有项目。找不到spring-boot-gradle-plugin-2.3.0.build-snapshot.jar（org.springframework.boot:spring-boot-gradle-plugin:2.3.0.build-snapshot:20200409.145011-519).在以下位置进行了搜索:https://repo.spring.io/snapshot/org/springframework/boot/spring-boot-gradle-plugin/2.3.0.build-snapshot/spring-boot-gradle-plugin-2.3.0.build-20200409.145011-519.jar

请找到我的gradle build

plugins {
    id 'org.springframework.boot' version '2.3.0.BUILD-SNAPSHOT'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

group = 'com.mycompany'
version = '0.0.1-SNAPSHOT' //TODO how does verioning work in this project?
sourceCompatibility = '1.8'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
    maven { url 'https://repo.spring.io/milestone' }
    maven { url 'https://repo.spring.io/snapshot' }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-integration'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.kafka:spring-kafka'
    implementation 'org.springframework.boot:spring-boot-starter-aop'

    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    testImplementation ('org.springframework.integration:spring-integration-test'){
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    testImplementation ('org.springframework.kafka:spring-kafka-test'){
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    testImplementation group: 'org.mockito', name: 'mockito-all', version: '1.10.19'
}

test {
    useJUnitPlatform()
}

如果您没有特别的理由使用snapshot版本，我建议使用release或milestone。

快照生成相当不稳定。如果你想看一看新的2.3版本的Spring Boot，你可能应该使用里程碑版本。对于今天，它将是2.3.0.m4。

为此，更改org.springframework.boot插件版本，如下所示：

id 'org.springframework.boot' version '2.3.0.M4'
