TeamCity - using setParameter to pass information between build steps

问题

I must be doing something differently than what was asked and answered here because the solution does not appear to be working for me: TeamCity, passing an id generated in one build step to a later build step

I want use a string generated by one build step in a final build step. So far I have set up an environmental variable called "TEST" that is empty. Both build steps use the Command Line Runner.

Build Step #1:

\##teamcity[setParameter name='env.TEST' value='test']

Build Step #2:

echo $TEST

echo %env.TEST%;

Placeholder for now, but if I could access the test string ('test') set in Build Step 1 I would be so happy.

回答1:

you need to echo that string, e.g.

echo "##teamcity[setParameter name='env.TEST' value='test']"

回答2:

What I found is that with long values, as soon as TeamCity is breaking down the log output into two separate lines echo will not work anymore - you have to use Write-Host instead.

Write-Host "##teamcity[setParameter name='env.TEST' value='test']"

This should always work, just a side note - this value will be available only on subsequent build steps.

回答3:

I think you have an extra "\" in there. Try removing that and add double quotes around it and it should work.

 "##teamcity[setParameter name='env.TEST' value='test']"

If it doesn't work try using Powershell runner type as I'm using that for setting it and it works.

To expand on the above answers, with powershell it would look like so in build step 1:

Write-Host "##teamcity[setParameter name='env.TEST' value='$test']"

...and you can use the value like this in step 2:

echo %env.Test%

Also as a note, you'll have to set env.Test in the TC build parameters to be equal to something. I just used a space since I know the value will be set via ps script. Hope this helps.

It has to be printed to STDOUT, I use cat with heredoc to avoid having to escape single quotes in the event of using variables to dynamically set config parameters. What is heredoc?

MYVARNAME=MYVALUE
cat <<EOF
##teamcity[setParameter name='myConfParameter' value='$MYVARNAME']
EOF

Result:

##teamcity[setParameter name='myConfParameter' value='MYVALUE']

Here is official ticket about addition double quotes and echo (Write-Host - OS dependency).
