My reactive choice parameter groovy script is following 
def command = ["/bin/bash", "-c", "git ls-remote --tags " + repourl]
def process = command.execute()
process.waitFor()
def t1 = []
def result = process.in.text.tokenize('
n')
for(i in result)

{ {color:#0747a6}

def tagName = i.split()[1].replaceAll('\\^{
}','').replaceAll('refs/tags/', '')
t1.add(tagName)
}

return t1

 

But when I check this script in in-process script approval it looks like this 

def command = ["/bin/bash", "-c", "git ls-remote --tags " + repourl]
def process = command.execute()
process.waitFor()
def t1 = []
def result = process.in.text.tokenize("
")
for(i in result)

{ {color:#FF0000}

def tagName = i.split()[1].replaceAll('^{}','').replaceAll('refs/tags/', '')
t1.add(tagName)
}

And when I approved it this script contains error
