Bamboo: Access script variable in subsequent maven task

Question

Hi All, I have seen many posts where people asking to access Bamboo variables in script but this is not about that. I am defining a variable in Shell Script task, as below, and then I would like to access that variable in the subsequent maven task. #!/bin/sh

currentBuildNumber=${bamboo.buildNumber}

toSubtract=1newVersion=$(( currentBuildNumber - toSubtract ))

echo "Value of newVersion: ${newVersion}" This one goes perfectly fine. However I have a subsequent maven 3 task where I try to access this variable by typing ${newVersion} I get below error versions:set-property -Dproperty="newThatversion" -DnewVersion="${bamboo.newVersion}" error 07-Jun-2019 14:12:20 Exception in thread "main" java.lang.StackOverflowErrorsimple
07-Jun-2019 14:12:21 Failing task since return code of [mvn --batch-mode -Djava.io.tmpdir=/tmp versions:set -DnewVersion=1.0.${newVersion}] was 1 while expected 0 Basically, I would like to automate the version number of the built jar files just by using ${bamboo.buildNumber} and subtracting some number so that I won't have to enter the new version number every time I run a build. Appreciate your help... thanks, P.S.

I posted it here as well because no one answered me there for 4 days and thought to ask to specific community! But mods had marked it as SPAM - probably because of duplicate posting.
