Eclipse 如何解决pom.xml中缺少工件的问题

我正在用java启动一个简单的aws dynamoDB测试。当然也有类似的进口产品

导入com.amazonaws.services.dynamodbv2.AmazonDynamoDB

为了解决这个问题，我将我的项目声明为Maven nature，并添加一个类似于pom.xml的依赖项

`<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>DynamoDBOperations</groupId>
<artifactId>DynamoDBOperations</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
      <source>1.8</source>
      <target>1.8</target>
    </configuration>
  </plugin>
</plugins>
</build>
<dependencies>
<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>bom</artifactId>
    <version>2.0.0</version>
</dependency>
</dependencies>
</project>

当我尝试进行RunAs-Maven安装时，我看到以下错误

Failed to execute goal on project DynamoDBOperations: Could not resolve 
dependencies for project DynamoDBOperations:DynamoDBOperations:jar:0.0.1- 
SNAPSHOT: Failure to find software.amazon.awssdk:bom:jar:2.0.0 in 
http://localhost:8081/artifactory/libs-release was cached in the local 
repository, resolution will not be reattempted until the update interval of 
central has elapsed or updates are forced -> [Help 1] 

我知道它想告诉我一些事情，但我不明白

在.m2下有一个repository文件夹，它的文件夹结构类似于我所期望的software/amazon/awssdk/bom/2.0.0，下面是bom-2.0.0.jar.lastupdated

java程序甚至还没有启动

import com.amazonaws.services.dynamodbv2.AmazonDynamoDB;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClientBuilder;
import com.amazonaws.services.dynamodbv2.model.AttributeDefinition;
import com.amazonaws.services.dynamodbv2.model.CreateTableRequest;
import com.amazonaws.services.dynamodbv2.model.CreateTableResult;
import com.amazonaws.services.dynamodbv2.model.KeySchemaElement;
import com.amazonaws.services.dynamodbv2.model.KeyType;
import com.amazonaws.services.dynamodbv2.model.ProvisionedThroughput;
import com.amazonaws.services.dynamodbv2.model.ScalarAttributeType;
public class DynamoDBOperations {


}

它告诉您，不存在用于software.amazon.awssdk的jar bom-2.0.0.jar

看一看这张照片

您必须在dependencyManagement中定义bom表。也看看

定义依赖项并执行maven命令时，maven会自动创建文件夹结构，即使它无法下载依赖项

import com.amazonaws.services.dynamodbv2.AmazonDynamoDB;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClientBuilder;
import com.amazonaws.services.dynamodbv2.model.AttributeDefinition;
import com.amazonaws.services.dynamodbv2.model.CreateTableRequest;
import com.amazonaws.services.dynamodbv2.model.CreateTableResult;
import com.amazonaws.services.dynamodbv2.model.KeySchemaElement;
import com.amazonaws.services.dynamodbv2.model.KeyType;
import com.amazonaws.services.dynamodbv2.model.ProvisionedThroughput;
import com.amazonaws.services.dynamodbv2.model.ScalarAttributeType;
public class DynamoDBOperations {
