Jenkins Pipeline waitUntil bash command returns certain string
I have a pipeline stage where I wait to get a certain string back from a sh script, and only when the strings match, continue to next stage, however, it doesn't work as expected:
node('master') {
stage("wait for bash completion") {
waitUntil {
def output = sh returnStdout: true, script: 'cat /tmp/test.txt'
output == "hello"
}
}
stage("execute after bash completed") {
echo "the file says hello!!!"
}
}
The execution is something like that:
+ cat /tmp/test.txt
[Pipeline] }
Will try again after 0.25 sec
[Pipeline] {
[Pipeline] sh
[workspace] Running shell script
+ cat /tmp/test.txt
[Pipeline] }
Will try again after 0.3 sec
[Pipeline] {
[Pipeline] sh
[workspace] Running shell script
+ cat /tmp/test.txt
[Pipeline] }
Will try again after 0.36 sec
...
(so on and so forth)
What am I missing?

From waitUntil's help:
Runs its body repeatedly until it returns true. If it returns false, waits a while and tries again. --
Your execution output looks exactly like that it is waiting for output == "hello" to match. Maybe the content of file /tmp/test.txt is not exactly hello. You might have some whitespace in it, e.g. new line as the last character.
