java - Gradle无法找到Spring核心jar

Question

我是使用gradle build的spring boot。直到昨天，gradle构建才得以顺利进行。但是今天我得到了以下错误;

Could not resolve all artifacts for configuration ':classpath'. Could not find spring-core.jar (org.springframework:spring-core:5.2.0.BUILD-SNAPSHOT:20190328.215418-203). Searched in the following locations: https://repo.spring.io/snapshot/org/springframework/spring-core/5.2.0.BUILD-SNAPSHOT/spring-core-5.2.0.BUILD-20190327.205120-195.jar Could not find spring-jcl.jar (org.springframework:spring-jcl:5.2.0.BUILD-SNAPSHOT:20190328.215418-203). Searched in the following locations: https://repo.spring.io/snapshot/org/springframework/spring-jcl/5.2.0.BUILD-SNAPSHOT/spring-jcl-5.2.0.BUILD-20190327.205120-195.jar

这是我的build.gradle文件

buildscript {
    repositories {
        mavenCentral()
        maven { url 'https://repo.spring.io/snapshot' }
        maven { url 'https://repo.spring.io/milestone' }
        maven {url "https://plugins.gradle.org/m2/" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.3.RELEASE")
    }
}

plugins {
    id 'org.springframework.boot' version '2.2.0.BUILD-SNAPSHOT'
    id 'java'
}

apply plugin: 'io.spring.dependency-management'
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'idea'

group = 'me.namila'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

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

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok'
    runtimeOnly 'mysql:mysql-connector-java'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

当访问相关的URL时，我能看到的是gradle正在搜索3月27日的构建(spring-jcl-5.2.0.BUILD-20190327.205120-195.jar)，而服务器具有28th的构建spring-jcl-5.2.0.BUILD-20190328.164750-201.jar。如何解决这个错误？我也添加了buildscript存储库。有什么建议吗？

Answer 1

正如Antoniossss在评论中所说，发生这种情况是因为快照构建失败。为了解决这个问题，我移至springboot的先前构建版本。我对build.gradle文件做了以下更改；

id 'org.springframework.boot' version '2.1.3.RELEASE'

将'2.2.0.BUILD-SNAPSHOT'更改为2.1.3版本。这解决了错误。 :)
