  1. POHudson as service on Windows - file system permissions
    text
    copied!<p>For some months we've run Hudson on a Windows XP "server" under a user account. This means someone manually logs in and starts Hudson via a .bat file (that sets up a few environment variables, then runs java -jar hudson.war)</p> <p>However a few recent power cuts have resulted in the requirement to have Hudson start automatically at the time the server boots up. So I've turned to looking at Hudson running as a Windows Service. This would allow Hudson to start automatically with Windows, and would not require a specific user account.</p> <p>I've managed to install it as a service, and I've changed hudson.xml so that the batch file is run rather than java directly. I do this because we build with git on Cygwin and SHELLOPTS=igncr must be set before bash starts java/Hudson.</p> <p>The service seems to start properly, and the web interface is present and functional. However, it appears that the user that Hudson is now running under is unable to write/modify existing jobs in C:\hudson:</p> <pre><code>FATAL: Could not checkout 4a121704f178123c36f6ab4e861b3c771953b187 hudson.plugins.git.GitException: Could not checkout 4a121704f178123c36f6ab4e861b3c771953b187 at hudson.plugins.git.GitAPI.checkout(GitAPI.java:382) at hudson.plugins.git.GitSCM$4.invoke(GitSCM.java:529) at hudson.plugins.git.GitSCM$4.invoke(GitSCM.java:521) at hudson.FilePath.act(FilePath.java:676) at hudson.FilePath.act(FilePath.java:660) at hudson.plugins.git.GitSCM.checkout(GitSCM.java:521) at hudson.model.AbstractProject.checkout(AbstractProject.java:833) at hudson.model.AbstractBuild$AbstractRunner.checkout(AbstractBuild.java:314) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:266) at hudson.model.Run.run(Run.java:948) at hudson.model.Build.run(Build.java:112) at hudson.model.ResourceController.execute(ResourceController.java:93) at hudson.model.Executor.run(Executor.java:118) Caused by: hudson.plugins.git.GitException: Error performing c:\cygwin\bin\git.exe checkout -f 4a121704f178123c36f6ab4e861b3c771953b187 at hudson.plugins.git.GitAPI.launchCommandIn(GitAPI.java:302) at hudson.plugins.git.GitAPI.launchCommand(GitAPI.java:276) at hudson.plugins.git.GitAPI.checkout(GitAPI.java:380) ... 12 more Caused by: hudson.plugins.git.GitException: Command returned status code 1: error: git checkout-index: unable to create file .gitignore (Permission denied) error: git checkout-index: unable to create file .gitmodules (Permission denied) error: git checkout-index: unable to create file Makefile (Permission denied) </code></pre> <p>I'm not really a Windows sort of person, but I thought perhaps if I added "Full Access" Security permissions to C:\hudson for the user "LOCAL_SERVICE" then that might fix it. Alas, it did not. I also tried full permissions for the user "Everyone" but that also did not solve the problem.</p> <p>What am I missing here? Is there any way to allow a process running as a Service unfettered access to a subdirectory on a local disk?</p>
