SpringBoot：无法传输工件

Question

在IntelliJ中启动新项目时，我遇到了一个问题：

< li>Maven构建总是成功终止 < li >“重新加载所有Maven项目”导致错误 < li >无法将org . spring framework . boot . spring application导入主类

这是我的pom.xml：

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>org.example</groupId>
        <artifactId>JavaTutorial</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <name>Java Tutorial Course API</name>
    
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-parent</artifactId>
                    <version>1.3.2.RELEASE</version>
                    <scope>import</scope>
                    <type>pom</type>
                </dependency>
            </dependencies>
        </dependencyManagement>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
                <version>1.3.2.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-autoconfigure</artifactId>
                <version>1.3.2.RELEASE</version>
            </dependency>
        </dependencies>
    
        <properties>
            <maven.compiler.source>7</maven.compiler.source>
            <maven.compiler.target>7</maven.compiler.target>
            <java.version>1.7</java.version>
        </properties>
    
    </project>

注意：我尝试添加

主要类别：

    package springbootstarter;
    
    import org.springframework.boot.SpringApplication;
    
    @SpringBootApplication
    public class CourseApiApp {
    
        public static void main(String[] args) {
    
        }
    }

尝试重新加载 Maven 项目时引发的错误：

org.springframework.boot:spring-boot-starter-web:pom:1.3.2.RELEASE failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-web:pom:1.3.2.RELEASE from/to central (https://repo.maven.apache.org/maven2): transfer failed for https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-web/1.3.2.RELEASE/spring-boot-starter-web-1.3.2.RELEASE.pom

org.springframework.boot:spring-boot-autoconfigure:pom:1.3.2.RELEASE failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced.

任何帮助将不胜感激。我正在寻找任何解决方案，但没有成功。




Answer 1

日志看起来非常干净，该项目正在尝试下载依赖项，但它无法下载。

org.springframework.boot:spring-boot-starter-web:pom:1.3.2.RELEASE failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-web:pom:1.3.2.RELEASE from/to central (https://repo.maven.apache.org/maven2): transfer failed for https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-web/1.3.2.RELEASE/spring-boot-starter-web-1.3.2.RELEASE.pom

因此，首先检查您与https://repo.maven.apache.org/maven2然后验证该依赖项和特定版本是否仍然存在，因为它确实是旧版本。如果是这样，请尝试强制下载依赖项。如果您使用maven，您可以使用：

mvn dependency:resolve

注意:请注意，如果您在代理后面，您必须配置代理以便能够被maven/gradle使用
