Issue with the first run of script created by seed job: 

org.jenkinsci.plugins.scriptsecurity.scripts.UnapprovedUsageException: script not yet approved for use

Hashs of seed job are programatically allowed. 

Groovy sandbox disabled.

useScriptSecurity=false

Once newly created job updated ( e.g. blank space in the pipeline or whatever) no additional approves needed and everything works as expected. 

Thank you,

Vadym
