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:
java.lang.NullPointerException: null

Thanks!
