Jenkinsfile 和 groovy 脚本 - 文件意外结束

Question

I need to have a one-liner sh script such as this

if. [-s filename.txt ] then echo 'don'\''t do something' exit 2 fi

but when I put this in sh " <>" I am getting the following error

/home/jenkins/workspace/<BLA_BLA>/script.sh: line 1: unexpected EOF while looking for matching `''

Not sure how to fix it. Could someone point me in the right direction?

Answer 1

The first issue is that you need to escape the backslash inside the sh block, so for example:

sh "if. [-s filename.txt ] then echo 'don'\\''t do something' exit 2 fi"

Then there is probably a problem with the oneliner script you posted as it doesn't work in plain bash for me either.

In the pipeline, you can use multiline string with """ , if I reformat the script you posted, it works correctly:

sh """
    if ! [ -s filename.txt ]; then
        echo 'don'\\''t do something'
        exit 2
    fi
"""

the output then is:

+ '[' -s filename.txt ']'
+ echo 'don'\''t do something'
don't do something
+ exit 2
ERROR: script returned exit code 2

Would that work for you?
