Question

我正在学习使用Spring集成，我正在使用他在网上找到的教程。在适配器上进行练习，我正在使用这个基本的pom文件：

<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>com.intertech.si</groupId>
    <artifactId>lab2-adapters</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>Spring Integration Lab 2</name>
    <description>Lab 2 - using adapters</description>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <springframework.version>4.0.4.RELEASE</springframework.version>
        <spring.integration.version>4.0.0.RELEASE</spring.integration.version>
        <spring.integration.xml.version>4.0.0.RELEASE</spring.integration.xml.version>
        <log4j.version>1.2.17</log4j.version>
    </properties>

    <dependencies>

        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-core</artifactId>
            <version>${spring.integration.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-stream</artifactId>
            <version>${spring.integration.version}</version>
        </dependency>

        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>${log4j.version}</version>
        </dependency>
    </dependencies> 
</project>

按照教程的说明，我需要添加这些依赖项：

<dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-file</artifactId>
            <version>${spring.integration.version}</version>
        </dependency>

但是当我这样做并且我尝试保存文件时，我在控制台日志上犯了很多错误：

    pom.xml /lab2-adapters-starter  line 1  Maven Dependency Problem

他的问题是特定于最后添加的依赖项，因为如果我尝试删除此文件并保存文件，我没有错误。

可能是什么事？

Answer 1

下载文件时出现问题。我不知道为什么，但Maven不能自己解决这个问题。到达本地存储库缓存，如果您没有更改它，请访问：[USER-DIR] .m2 \ repository，并删除＆＃34; org \ springframework \ integration＆＃34;。

Answer 2

这个pom.xml文件在我的PC环境中正常运行。但我的本地m2存储库中没有任何其他旧spring integration jar。所以，根据你的错误信息：

引起：org.eclipse.aether.resolution.ArtifactResolutionException：未能转移 org.springframework.integration：弹簧集成文件：POM：4.0.0.RELEASE 来自https://repo.maven.apache.org/maven2的缓存在本地存储库，解决方案在更新之前不会重新尝试中心间隔已经过去或强制更新。原始错误：无法转移神器 org.springframework.integration：弹簧集成文件：POM：4.0.0.RELEASE 从/到中央（https://repo.maven.apache.org/maven2）： repo.maven.apache.org:Errore temporaneo nella risoluzione del nome

您是否注意到https://repo.maven.apache.org/maven2 中的＃34;已缓存在本地存储库中＆＃34;消息中的消息。？

或许，您本地存储库中的先前版本spring integration jar与新spring integration jar.

冲突

1）第一种方式（我确信）
我认为您需要删除文件夹$HOME/.m2/repository/org/springframework/integration

之后，使用mvn命令或Eclipse重建并更新 maven 。

2）第二种方式（我不确定）
你不需要删除任何旧罐子。您只需使用mvn命令或Eclipse执行强制更新到存储库。
