</project>

能够使用标准 mvn 命令从命令行成功清理、编译和安装此项目...

但是，在 Eclipse Juno 的问题 Pane 中，我有以下 2 个错误:

缺少 Artifact org.kitchen-eel:json-schema-validator:jar:1.2.1 pom.xml/com.cloudst line 45 Maven 依赖问题

ArtifactTransferException:无法传输 org.kitchen-eel:json-schema-validator:jar:1.2.1

来自 http://repo.maven.apache.org/maven2缓存在本地存储库中，
在 central 的更新间隔达到之前不会重新尝试解析
已过去或强制更新。原始错误:无法传输 Artifact
org.kitchen-eel:json-schema-validator:jar:1.2.1 从/到中央
(http://repo.maven.apache.org/maven2):

转账失败 http://repo.maven.apache.org/maven2/org/kitchen-eel/json-schema-validator/1.2.1/json-schema-validator-1.2.1.jar .

为什么它在命令行中工作但 m2eclipse 发布问题？

感谢您抽时间阅读...

Answer 1

这是解决 Eclipse 中 Maven 项目中可能发生的错误“ArtifactTransferException:Could not transfer artifact”的非常简短的提示。

解决步骤:

 1. Open folder by running this text (without Quotes) in Search Explorer of Window “%USERPROFILE%\.m2″.
 2. After running above command, “m2″ folder of maven will open. Now search for file (without Quotes) “*.lastUpdated”.
 3. In this step, delete all the files found by running Step 2.
 4. Now go to Eclipse project and select “Maven | Update Dependency” or “Maven | Update Project”.

快乐编码。
