编译使用旧版本Giraph和Maven的项目

Question

我有一个项目是从另一个组开发的，使用的是旧版本的Giraph。

该项目基于graph项目本身；项目结构和文件与graph完全相同，只是在graph-examples中定义了一些用于更复杂的map-reduce图形操作的.java源代码。由于该项目是Giraph项目的扩展，因此使用Maven对该项目进行编译和打包，Maven也是Giraph项目的构建工具。

我找不到这个项目所基于的Giraph的确切版本，但我可以发现编译这个项目需要0.2-SNAPSHOP的giraph-parent，而且它是相当旧的。

当前问题是，当我尝试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成功地编译/打包最近的Giraph (从官方主页)。错误消息显示我的项目文件夹中没有.git文件夹，但只有.svn文件夹。有没有人能找出这个错误的确切原因？

谢谢

Answer 1

mavanagaiata是一个maven插件，它将git提交信息添加到构建中，这样您以后就可以跟踪您的工件到特定的修订版。如果你不是从git仓库内部构建的，那么你需要禁用这个特性。您可以通过将-Dmavanagaiata.skipNoGit=true附加到mvn命令执行来临时完成此操作。

可以在the plug-in website上找到更完整的插件文档。
