TeamCity Current Date variable in MMdd format

Question

In TeamCity is there an easy way to get a variable for the current date in the format MMdd (eg 0811 for 8-Aug)?

My google-fu did not turn up an existing plugins. I look

Answer 1

If you only want to have one-line bash command in a build step, just use as below.

echo "##teamcity[setParameter name='build.timestamp' value='$(date +%%m%%d)']"

(double % symbol is for TeamCity own escape rule to use % character)

It will set a MMdd parameter value right after the execution during runtime so very useful to put at any build step. Then, you can retrieve a parameter value afterward.

Note that you should create build.timestamp parameter firstly to TeamCity project.

A step further, I made a simple bash script to have bash date format timestamp. This script will set timestamp to whatever bash supported datetime format and parameter name to TeamCity.

name=""  # TeamCity parameter name
format="%Y-%m-%dT%H:%M:%S%z"  # ISO8601 format by default
result=""  # a TeamCity parameter value to be set

for ARGUMENT in "$@"
do
    KEY=$(echo "$ARGUMENT" | cut -f1 -d=)
    VALUE=$(echo "$ARGUMENT" | cut -f2 -d=)

    case "$KEY" in
            name)              name=${VALUE} ;;
            format)     format=${VALUE} ;;
            *)
    esac
done

result=$(date "+$format")

echo "##teamcity[setParameter name='$name' value='$result']"

Below usage will set ISO8601 format timestamp to build.timestamp parameter.

./teamcity_datetime.sh name=build.timestamp

If you want to set only MMdd, the execution could be as below.

./teamcity_datetime.sh name=build.timestamp format="%%m%%d"

Similar to the Date Build Number plugin mentioned in this answer, there exists a derived plugin called Formatted Date Parameter. It provides a customizable parameter build.formatted.timestamp that can be used out of the box in fields or other parameters. No need for a separate build step.
