A Groovy task that prefixes new SQL migration files with a timestamp precise to milliseconds. The following usage will add a prefix to any SQL file in a hardcoded directory that does not begin with an number and double leading underscore: $ gradle prefixNewMigrations
task prefixNewMigrations {
fileTree(dir: 'dev/src/db/listhub').exclude({ isFilePrefixed(it.file) }).each { file ->
doLast {
def timestamp = new Date().format('yyyyMMddHHmmssSSS', TimeZone.getTimeZone('GMT'))
println "Renaming $file.name to ${timestamp}__$file.name"
file.renameTo("$file.parentFile.absolutePath$file.separator${timestamp}__$file.name")
// Sleep for a moment to avoid prefix conflicts when renaming multiple files
sleep(1*1000)
}
}
}
def isFilePrefixed(file) {
return (file.name ==~ '^\\d+__.*\\.sql\$')
}

Thanks for sharing this!
I had to do something similar, but I had to plug it into a maven build, so I could only use pure Groovy. You can find this Gist here: https://gist.github.com/SlevinBE/7233913
