Question

我有一个项目是从另一个小组开发的，并使用旧版本的Giraph。

该项目基于Giraph项目本身;项目结构和文件与Giraph完全相同，只是在giraph-examples中定义了更复杂的map-reduce图操作的一些.java源。由于该项目是Giraph项目的扩展，Maven用于编译和打包此项目，这也是Giraph项目的构建工具。

我无法找到这个项目完全基于Giraph的版本，但我发现编译这个项目需要0.2-SNAPSHOP的giraph-parent，而且它很老。

目前的问题是，当我尝试进行mvn验证时出现错误; 屏幕上打印的mvn消息如下：

此外，我可以在相同的环境中使用Maven成功编译/打包最近的Giraph（来自官方主页）。错误消息说我的项目文件夹中没有.git文件夹，但只有.svn文件夹。有人可以准确找出这个错误的原因吗？

谢谢

Answer 1

mavanagaiata是一个maven插件，它将git提交信息添加到构建中，以便您以后可以将工件追溯到特定修订版。如果您不是从git存储库内部构建，则需要禁用此功能。您可以通过将-Dmavanagaiata.skipNoGit=true附加到mvn命令执行来临时执行此操作。

可以在the plug-in website上找到更完整的插件文档。
