如何通过带有Java代码的jenkins-cli或客户端api或ssh-slave-plugin添加一个Jenkins从节点？

标签： java jenkins ssh jenkins-pipeline

我已阅读Jenkins Slave Node setup和How can I add Jenkins slave nodes via the CLI?

  1. 我的詹金斯地址：https://perf.jenkins.mydomain.com;
  2. 我从jenkins-cli.jar下载了https://perf.jenkins.mydomain.com/cli；
  3. 我使用命令java -jar jenkins-cli.jar -s https://perf.jenkins.mydomain.com/ help，但是它不输出任何信息或错误，为什么？
  4. 因为我有很多机器需要添加/删除jenkins主节点作为从节点，所以我想使用简单的方法，例如：jenkins-cli.jar或ssh-slaves-plugin，如上所述，因此我尝试使用ssh-slaves-plugin;
  5. 我使用这样的代码：https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/src/test/java/hudson/plugins/sshslaves/SSHLauncherTest.java#L170，而我的代码是：
    @RequestMapping(value = "/test", method = RequestMethod.GET)
    public Map<String, Boolean> test() {
        Map<String, Boolean> result = new HashMap<>();

        SystemCredentialsProvider.getInstance().getDomainCredentialsMap().put(Domain.global(),
                Collections.singletonList(
                        new UsernamePasswordCredentialsImpl(CredentialsScope.SYSTEM, "dummyCredentialId", "perf-test", "myuser", "mypassword")
                )
        );

        SSHLauncher launcher = new SSHLauncher("10.10.10.10", 22, "dummyCredentialId", null, null, null,
                null, 3, 1, 1, new KnownHostsFileKeyVerificationStrategy());

        DumbSlave dumb = null;
        try {
            dumb = new DumbSlave("slave-test", "", launcher);
            dumb.setNodeDescription("dummy-description");
            dumb.setNumExecutors(1);
            dumb.setMode(Node.Mode.NORMAL);
            dumb.setRetentionStrategy(RetentionStrategy.NOOP);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Descriptor.FormException e) {
            e.printStackTrace();
        }

        try {
            final Jenkins jenkins = Jenkins.get();
            jenkins.checkPermission(Computer.CREATE);
            jenkins.addNode(dumb);
        } catch (IOException e) {
            e.printStackTrace();
        }
        result.put("success", true);
        return result;
    }

我有以下问题：

  1. 如何在代码上设置jenkins主信息？
  2. 运行它时，它输出错误：
