概述：本文讲述的是在eclipse中如何构建geoserver源码工程，其中涉及到了jdk，github，marven等。
1、安装git
从（http://git-scm.com/download/win），获得Git-1.9.0-preview2014021 7.exe文件，直接安装即可。安装成功后，在任何处所右击鼠标，出现如下图所示：
2、从git中签出geoserver源码
点击“Git GUI”将呈现如下界面，选择“克隆已有版本”，进入源码克隆界面，输入响应的source Location（源码地点地位git://github.com/geoserver/geoserver.git） 和 Target Location（本地存储地位）。
克隆已有版本
输入参数
克隆完成后，源代码的组织如下：
3、下载并配置Maven
（http://maven.apache.org/download.cgi）选择apache-maven-3.21-bin.zip，maven是号令行法度，将获得的紧缩包解压，解压后文件组织如下：
并添加D:softwarejavawebmavenin到path变量中。
4、通过maven构建源码
4.1 跳转路径到geoserver的src目录下
C:UsersAdministrator>d: D:>cd D:opengisopengissrc D:opengisopengissrc>4.2 临时将maven的路径添加至环境变量中
执行如下命令：
Set PATH = “maven_dir/bin”;％PATH％4.3 构建工程
执行如下命令，构建工程：
mvn clean install mvn -DskipTests clean install
注意：第一条号令在构建的同时履行测试用例测试类文件，在号令履行过程中有可能会呈现错误；第二条号令在构建时，不进行测试，不会有测试不经由过程的异常。
执行命令输出：
