How to specify branch name for shared library as environment variable - docker

Question

I want to refer/specify (syntax) branch which is set as an environment variable for Jenkins shared library which will be provide during docker container.
For Example:
#Library(['my-shared-library', BRANCH_NAME])
Tried using ${BRANCH_NAME} ${env.BRANCH_NAME}
I will provide BRANCH_NAME as environment variable in docker-compose.yml
Also i want to get the env variable effected in org.jenkinsci.plugins.workflow.libs.GlobalLibraries.xml
like if i set PIPELINE_VERSION as env variable
<?xml version='1.1' encoding='UTF-8'?>
<org.jenkinsci.plugins.workflow.libs.GlobalLibraries plugin="workflow-cps-global-lib#2.15">
<libraries>
<org.jenkinsci.plugins.workflow.libs.LibraryConfiguration>
<name>XXXXXXXXXXXX</name>
<retriever class="org.jenkinsci.plugins.workflow.libs.SCMSourceRetriever">
<scm class="jenkins.plugins.git.GitSCMSource" plugin="git#3.12.0">
<id>XXXXXXXXXXXXXXXXXXXXXXXX</id>
<remote>XXXXXXXXXXXXXXXXXXX</remote>
<credentialsId>jXXXXXXXXXXXXXXXXXXXX</credentialsId>
<traits>
<jenkins.plugins.git.traits.BranchDiscoveryTrait/>
</traits>
</scm>
</retriever>
<defaultVersion>${PIPELINE_RELEASE_VERSION}</defaultVersion>
<implicit>true</implicit>
<allowVersionOverride>true</allowVersionOverride>
<includeInChangesets>false</includeInChangesets>
</org.jenkinsci.plugins.workflow.libs.LibraryConfiguration>
</libraries>
</org.jenkinsci.plugins.workflow.libs.GlobalLibraries>
Thanks,

I don't think anyway it possible to make the environment variable available for org.jenkinsci.plugins.workflow.libs.GlobalLibraries.xml. But If you use Jenkins Code As Configuration plugins, you can pass the variable from docker-compose and make that available to the config file, and when Jenkins load the config file to prepare config for Jenkins would work.
