1、生成密钥

2、添加依赖

<dependency>
  <groupId>org.gitlab4j</groupId>
  <artifactId>gitlab4j-api</artifactId>
  <version>5.3.0</version>
 </dependency>

Java代码实现

统计所有项目的代码行数： 

private String url = "gitlab的仓库地址";

    private String authToken = "用户的token";

    private GitLabApi gitLabAPI = new GitLabApi(url, authToken);


    /**
     * 统计每个项目的代码行数
     *
     * @throws Exception
     */
    @Test
    public void codeTotalCount() throws Exception {
        //拉取属于我的所有项目
        List<Project> projectList = gitLabAPI.getProjectApi().getOwnedProjects();
        for (Project proj : projectList) {
            String namespace = proj.getNamespace().getFullPath();
            String name = proj.getPath();
            String url = proj.getWebUrl();
            log.info("项目命名空间：{}, 项目名称：{}, 项目地址：{}", namespace, name, url);
