Question

有一个mahout-math项目on github。我怎么能用它制作一个罐子？我需要使用最新的代码，因为我唯一能找到located here的代码是错误的。我得到的错误：

Answer 1

尝试以下

mkdir somedirectory
cd somedirectory
git clone https://github.com/apache/mahout.git
cd mahout/
cd math/
mvn clean package
ls target/mahout-math-0.8-SNAPSHOT.jar

你需要在你正在使用的任何操作系统上安装git和maven（mvn）。

Answer 2

git clone git://github.com/apache/mahout.git && cd mahout && mvn clean package假设你有git和maven。这将在target子文件夹中为您提供一个jar。

如何用github源制作jar？
