Starting jenkins connection as jenkins

Question

I think this is very simple question but can't find solution anywhere. I have to run my jenkins plist file ( or just .jar file ) as jenkins, not as an admin. This is how my file looks right now:

<key>Label</key>
    <string>com.example.ci</string>
    <key>ProgramArguments</key>
    <array>
        <string>sudo</string>
        <string>/usr/bin/java</string>
        <string>-Djava.awt.headless=true</string>
        <string>-jar</string>
        <string>/Users/Shared/Jenkins/Home/slave.jar</string>
        <string>-jnlpUrl</string>
        <string>http://[adres]/slave-agent.jnlp
</string>
        <string>-secret</string>
        <string>841557ed784ead7secret[334b3ac76fe1618e375
</string>
    </array>
    <key>KeepAlive</key>
    <true/>
    <key>StandardOutPath</key>
    <string>/Users/Shared/Jenkins/Home/stdout.log</string>
    <key>StandardErrorPath</key>
    <string>/Users/Shared/Jenkins/Home/error.log</string>

I was trying to add command to switch to jenkins with:

sudo su jenkins

so I tried adding something like this:

<key>Jenkins user</key>
        <string>what.to.put.here</string>
        <key>OtherArguments</key>
        <array>
            <string>sudo</string>
            <string>su</string>
            <string>jenkins</string>
        </array>

before those lines above, but as I see I'm still not logged as jenkins. When I do this from command line with those commands I wrote - than it works, but I want it to run when system starts.

EDIT:

after gaige answer I added:

<key>UserName</key>
<string>jenkins</string>

but I still don't have permissions to directory to which jenkins user has.

If you are using a system launchctl plist, then you can just add the UserName key:

<key>UserName</key>
<string>jenkins</string>

at the same level as your other keys in the plist. And then remove all the sudo related stuff.

Note that this must be a system launchd (located in /System/Library/LaunchDaemon or /Library/LaunchDaemon ), otherwise you won't have permissions to use the user in question.
