Question

我尝试做run-as - ＆gt; mvn在eclipse中安装，但后来我收到错误但我不知道如何解决它。

这是错误：

Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.0:shade (default) on project reminder: Execution default of goal org.apache.maven.plugins:maven-shade-plugin:2.0:shade failed: Plugin org.apache.maven.plugins:maven-shade-plugin:2.0 or one of its dependencies could not be resolved: Failed to collect dependencies for org.apache.maven.plugins:maven-shade-plugin:jar:2.0 (): Failed to read artifact descriptor for commons-io:commons-io:jar:1.3.2: Could not transfer artifact org.apache.commons:commons-parent:pom:3 from/to central (http://repo.maven.apache.org/maven2): No response received after 60000 -> [Help 1]

我的pom看起来像这样：

Answer 1

对于遇到同样问题的其他人，我可以通过回退到Maven 3.0.x版来解决问题。因为我的项目还没有为版本3.1.x做好准备。

Answer 2

看起来像是互联网连接问题：

Could not transfer artifact org.apache.commons:commons-parent:pom:3 
from/to central (http://repo.maven.apache.org/maven2): 
No response received after 60000

如果重复命令会怎样？该文件应位于中央仓库：http://search.maven.org/#artifactdetails%7Corg.apache.commons%7Ccommons-parent%7C3%7Cpom

您可以尝试再次运行该命令吗？

Answer 3

可能已经解决了这个问题，但其他人都尝试将maven-shade-plugin更新为2.1。您可以通过编辑pom.xml来完成此操作。
