Install Slave as Windows Service [message #1016519]

I've seen the bug report for this issue, https://bugs.eclipse.org/bugs/show_bug.cgi?id=401530. Unfortunately, I didn't see a work around for this. Is there a way to install a slave as a windows service with Hudson 3.0?

Thanks -- Dan'l

it looks like that bug link is no longer valid. Here's another one. https://bugs.eclipse.org/bugs/show_bug.cgi?id=382490
That one hasn't suggested a workaround either.

The issue happened because of Java Native Access library required to install as windows service was moved to a plugin. This broke installing as service. I marked the bug to be fixed for 3.0.2, and we will look in to that try to fix fro 3.0.2.

I have fixed it in Hudson 3.1.0. But it will be released in beginning of July. Mean while I created a war (version 3.0.1-b3) for immediate use

I've just tiried that. I'm using role-based authorization strategy and active directory plugins for security. The service installed itself successfully but there is a problem with connection.

If I do not specify credentials I got 403 exception

Failing to obtain https://<MyTestHudsonURL>/computer/nemedia/slave-agent.jnlp

If I specify credentials (-jnlpCredentials <user>:<password>) I got NoClassDefFoundError exception

The only way I was able to get slave connected to master was to either grant Anonymous user Read permission (which is not acceptable in production env) or download slave-agent.jnlp to my file system and point out to that file in config. In both cases exception was thrown but the connection was successful.

Are you planning to integrate slave windows service somehow better with hudson security model or I should use workaround with local slave-agent.jnlp file ?

Hi, this part of slave .jnlp has no effect since java java 7u45:
<property name="hudson.showWindowsServiceInstallLink" value="true"/>
This property is not passed so menu option is NOT shown - starting from java 7u45 launch descriptor (JNLP file) need to be signed in order to set 'insecure' system properties.

This also needs to be fixed.
