尝试使用标准差Java

Question

嗨，我正在尝试使用Apache Commons Math的标准偏差库。我无法导入该库，因为下载zip文件后找不到jar文件。我是否遗漏了一些明显的内容？

Answer 1

Open the Download Commons Math page and download the current binaries release. At the moment this is commons-math3-3.0-bin.zip. From your comments it is obvious that you downloaded the archive containing sources.

Answer 2

1. Unzip the zip file 7zip works great for unzipping things

2. Make sure the jar is in the build path for the compiler How to add Jars to your build path in eclipse

3. Profit???

Are you sure the jar is in the classpath?

I see the jars in here, Download it from here

Answer 3

Get a build+dependancy management tool and you will not have problems like this. I suggest you to go with apache buildr ( quick start ) and a buildr file like this:

repositories.remote << 'http://www.ibiblio.org/maven2'

define 'killer-app' do
  project.version = '0.1.0'
  compile.with 'org.apache.commons:commons-math:jar:2.0'
  package :jar
end
