I'm using `ssh-slaves-plugin` and write some codes, like the below:

@RequestMapping(value = "/test", method = RequestMethod.GET)
public Map<String, Boolean> test() {
    Map<String, Boolean> result = new HashMap<>();

    // username is my jenkins user

    // password is my jenkins password

    UsernamePasswordCredentialsImpl credentials = new UsernamePasswordCredentialsImpl(CredentialsScope.SYSTEM, "dummyCredentialId", "perf", "myname", "mysceret");
    SystemCredentialsProvider.getInstance().getDomainCredentialsMap().put(Domain.global(),
            Collections.singletonList(
                    credentials
            )
    );

    // ip is my slave ip
    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();
    }

    // I see https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/src/test/java/hudson/plugins/sshslaves/SSHLauncherTest.java#L181

    // use JenkinsRule, so I use Jenkins.getInstanceOrNull
    try {
        Jenkins.getInstanceOrNull().addNode(dumb);
    } catch (IOException e) {
        e.printStackTrace();
    }
    result.put("success", true);
    return result;
}

when I run it, return error, stack:
