春行家錯誤

Question

我在使用Spring MVC與Maven開發Web應用程序，但是當我更新我依賴我得到這個消息：

 
5/6/10 10:09:50 AM CEST: Build errors for amundsen.web; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.4.1:resources (default-resources) on project amundsen.web: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.4.1:resources failed: Plugin org.apache.maven.plugins:maven-resources-plugin:2.4.1 or one of its dependencies could not be resolved: Unable to get dependency information for org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.4.1: Failed to process POM for org.apache.maven.plugins:maven-resources-plugin:maven-plugin:2.4.1: Non-resolvable parent POM org.apache:apache:6 for org.apache.maven:maven-parent:13: Failed to resolve POM for org.apache:apache:6 due to The repository system is offline and the requested artifact is not locally available at /home/waleed/.m2/repository/org/apache/apache/6/apache-6.pom

from the specified remote repositories: 
    plexus.snapshots (http://oss.repository.sonatype.org/content/repositories/plexus-snapshots, releases=false, snapshots=true), 
    central (http://repo1.maven.org/maven2, releases=true, snapshots=false) 

我的Maven依賴是：

有什麼想法？

Answer 1

由於您的某個依賴關係，構建不會失敗，因爲maven-resources-plugin的某個依賴關係而失敗。更確切地說，Maven是不能夠解決org.apache:apache:pom:6這爲中心提供雖然：

http://repo1.maven.org/maven2/org/apache/apache/6/apache-6.pom

是否使用m2eclipse的？它是否配置爲離線運行（跟蹤似乎表明）？或者這可能與MNGECLIPSE-1802有關？

嘗試在命令行上運行maven，它應該可以工作，並且可以解決m2eclipse的問題。

Answer 2

Maven無法解析org.apache：apache：pom：6，因爲它離線工作。 在脫機模式下工作時，不在本地存儲庫中的依賴項將無法訪問。

嘗試從命令提示符下運行Maven，並檢查當前配置

Answer 3

你是下一個代理？

嘗試配置mvn代理。

我是用同樣的問題，並正確配置maven上的代理，所有的作品！
