Easily and quickly parse CSV/TSV line

parseCsv.groovy

List<String> values = []
int start, stop

// Quickly parse TSV line
while (true) {
    stop = line.indexOf('\t', start)
    if (stop < 0) break;
    values.push(line.substring(start, stop))
    start = stop + 1
}

// Now you got all values in a list / array, just use them:

final def dataCenter = values[0]
final def env = values[1]
final def hostName = values[2]
final def licenseID = values[3]
