eclipse - 在 Eclipse(Kepler) 中创建 MAVEN 项目时出错

Question

I am trying to create simple maven project in Eclipse . It is created but while building Workspace it is giving an Error . also there is an error in pom.xml.

<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.students.app</groupId>
  <artifactId>students-application</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <version>2.5</version>
        </plugin>
    </plugins>
  </build>
</project>

This is my pom.xml I am getting an Error as following

Multiple annotations found at this line:
    - Failure to transfer org.apache.maven.plugins:maven-resources-
     plugin:pom:2.5 from http://repo.maven.apache.org/maven2 was cached in

what should I do?

Answer 1

问题可能是某些“.lastUpdated”可能会阻止您的下载，您需要删除“.lastUpdated”并更新 maven 项目。

找到 {user}/.m2/repository 并删除所有“*.lastUpdated”文件 你可以通过以下方式做到这一点

在 %USERPROFILE%.m2 中搜索 *.lastUpdated，然后删除 Eclipse 报告有问题的文件

或

cd %userprofile%\.m2\repository
for /r %i in (*.lastUpdated) do del %i

完成后，从 eclipse 更新您的 Maven 项目。
