百度搜索“搭建maven私有仓库”，搜索到的结果几乎都是使用nexus

不一样的简单

如果了解maven上传原理，完全没必要搞得那么复杂庞大，区区不足百行代码就可以实现一个私有仓库。

maven上传的核心本质是:使用Http PUT上传,使用Http GET下载。再简单不过的代码如下:

@WebServlet("/")
public class RepositoryServer extends HttpServlet
{ 
	/**储存位置 */
	private File path; 
	public void init(ServletConfig config) throws ServletException
	{
		super.init(config);
		//或者指定其他位置
		 path = new File(config.getServletContext().getRealPath("/repository"));  
	} 
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
	{
		String reqPath = req.getServletPath();
		File reqFile = new File(path, reqPath);
		if (!reqFile.exists())
		{
			resp.sendError(HttpServletResponse.SC_NOT_FOUND);
			return;
		}
		if (reqFile.isDirectory())
		{ 
			resp.sendError(HttpServletResponse.SC_FORBIDDEN);
		} else
		{
			try (OutputStream out = resp.getOutputStream())
			{
				Files.copy(reqFile.toPath(), out);
			}
		}
	} 
	protected void doPut(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
	{ 
		String reqPath = req.getServletPath();
		File reqFile = new File(path, reqPath);
		if (reqPath.endsWith("/"))
		{
			reqFile.mkdirs();
		} else
		{
			File parentDir = reqFile.getParentFile();
			if (!parentDir.exists())
			{
				parentDir.mkdirs();
			}
			try (InputStream in = req.getInputStream())
			{
				Files.copy(in, reqFile.toPath(), StandardCopyOption.REPLACE_EXISTING);
			}
		}
	} 
}

 测试上传和引用(这里执行gradle使用,maven一样参考)

apply plugin: 'java'
apply plugin: 'maven'
version "0.9.9.1"
group "cn.heihei.testproject"  
project.ext.artifactId = "model"

repositories {
    jcenter()
}

dependencies {
   
    testImplementation 'junit:junit:4.12'
}
tasks.withType(JavaCompile) {
    options.encoding = "UTF-8"
} 
task sourcesJar(type: Jar) {
    classifier = 'sources'
    from sourceSets.main.allSource 
}
artifacts {
    archives sourcesJar 
}
jar {
    manifest {
        attributes('Implementation-Title': project.name,
                'Implementation-Version': project.version)

    }
} 
uploadArchives{
    repositories {
        mavenDeployer{
            repository(url:"http://localhost:8080/RepositoryServer/") 
            pom.project{
                version project.version
                groupId project.group
                packaging 'jar'
                artifactId project.ext.artifactId
            }
        }
    }
}

 

apply plugin: 'java'
 
repositories { 
	maven{
		url "http://localhost:8080/RepositoryServer/"  
	}
    jcenter()
}

dependencies {
     implementation 'cn.heihei.testproject:model:0.9.9.1'
    testImplementation 'junit:junit:4.12'
}

 bash结果
