JAVA程序实现 maven本地jar包安装

前段时间研究heritrix ,要搭建一个本地项目,但是发现很多jar包都下不下来(可恶的防火墙), 无赖只有自己手动安装本地maven库了.

于是动手写了个小程序,来实现本地jar包的安装.

废话不多说,上代码

package com.local.install;import java.io.BufferedReader;import java.io.File;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.util.ArrayList;import java.util.List;import java.util.Properties;public class InstallMavenJar {/** * 扫描所有的jar包 * @return */public List<String> scanJars(){String filePath = getRootDirectory();List<String> jars = new ArrayList<String>();if(filePath == null || "".equals(filePath.trim())){System.out.println("对不起没有找到,librariesPath,请检查配置");return jars ;}File file = new File(filePath);if(file.isDirectory()){File [] files = file.listFiles();for(File f : files){if(f.isDirectory()){continue;}String fileName = f.getName();if(fileName.endsWith(".jar")){jars.add(f.getAbsolutePath());}}return jars;}String fileName = file.getName();if(fileName.endsWith(".jar")){jars.add(file.getAbsolutePath());}return jars;}/** * 执行安装 */public void installMavenLib(){List<String> jars = scanJars();Runtime runtime = Runtime.getRuntime();for(String jar : jars){String mavenCmd = getMavenPath()+"mvn install:install-file -Dfile=";int index = jar.lastIndexOf("\\");String jarName = jar.substring(index+1);String[] splits = jarName.split("-");String version = "";String groupId = "";for(String s : splits){if(s.contains(".jar")){int suffixIndex = s.indexOf(".jar");version = s.substring(0,suffixIndex);int groupIndex = jarName.indexOf(version);groupId = jarName.substring(0,groupIndex-1);}}mavenCmd += jar;mavenCmd += " -DgroupId="+groupId;mavenCmd += " -DartifactId="+groupId;mavenCmd +=" -Dversion="+version;mavenCmd +=" -Dpackaging=jar";System.out.println("-*-*-*-*-*-*开始安装"+groupId+"-*-*-*-*-*-*");try {String[] cmds = new String[]{"cmd", "/c",mavenCmd}; Process p = runtime.exec(cmds);//InputStream in = p.getErrorStream();InputStream in = p.getInputStream();BufferedReader reader = new BufferedReader(new InputStreamReader(in));String line = null;System.out.println("-*-*-*-*-*-*执行结果如下-*-*-*-*-*-*");while ( (line = reader.readLine()) != null ){System.out.println(line);}p.destroy();} catch (IOException e) {e.printStackTrace();}}}/** * 获取jar包所在的根目录 * @return */public String  getRootDirectory(){InputStream in = InstallMavenJar.class.getClassLoader().getResourceAsStream("libraries.properties");Properties props = new Properties();try {props.load(in);String filePath = props.getProperty("librariesPath");return filePath;} catch (IOException e) {e.printStackTrace();}return null;}/** * 获取maven的路径 * @return */public String getMavenPath(){InputStream in = InstallMavenJar.class.getClassLoader().getResourceAsStream("libraries.properties");Properties props = new Properties();try {props.load(in);String filePath = props.getProperty("mavenPath");return filePath;} catch (IOException e) {e.printStackTrace();}return null;}public static void main(String[] args) {InstallMavenJar install = new InstallMavenJar();install.installMavenLib();}}

代码中的获取maven 目录和jar包所在的目录,需要在配置文件中配置.

librariesPath=F:\\tomcat\\tomcat7\\webapps\\activiti-explorer\\WEB-INF\\libmavenPath=D:/maven/apache-maven-3.2.3/bin/

整个项目结构如下图

将配置文件置于根目录下即可.

代码中的getmavenpath 和getrootdirectory 方法可以合并成一个 返回map就行了. 还少了很多资源的浪费. 但是作者当时弄的时候是后来加的 代码都搞得差不多了. 就直接copy上去了. 有兴趣的童鞋可以改改.
