提问：maven deploy timeout 错误

在对maven工程执行 mvn deploy时，时常在上传到一半时，报出超时的错误。

如下：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy (default-deploy) on project com.xx.xx.xx.project: Failed to deploy artifacts: Could not transfer artifact com.xx.xx.xx.project:pom:1.0.0-20110830.011730-4 from/to rd_snapshot (http://remote/artifactory/rd_snapshot): Error transferring file: Connection timed out: connect -> [Help 1]
