The pipeline domain specific language is based on groovy. Groovy does not
expand variable references in strings surrounded by single quote characters
(ASCII 0x27). Groovy expands variable references in strings surrounded by
double quote characters (ASCII 0x22). A groovy variable reference in a
string can have the same syntax as a bash variable reference.
Thus, your text:
sh """
echo ${mytime}
"""
attempts to resolve the groovy variable 'mytime'.
If you had used:
sh '''
echo ${mytime}
'''
it would attempt to resolve the shell variable 'mytime'.
See http://groovy-lang.org/syntax.html#_single_quoted_string and
http://groovy-lang.org/syntax.html#_double_quoted_string for more details.
