Reach User Defined Build Settings inside exportOptionsPlist - ios

Question

I have a project which consists of different targets for different build environments. I'm getting IPA file on Jenkins with xcodebuild. I want to define one exportOptionsPlist file and assign a different variable for different targets. For example, for method, Dev target should have development and Prod target should have app-store. For achieving this I'm defining User-Defined settings in Build Settings.
P.S: Every target has only Debug and Release options and every target has IPA_EXPORT_METHOD.
My problem is that I'm getting below error when trying to get the IPA (Reading IPA_EXPORT_METHOD from the ExportOptionsPlist file):
Error Domain=IDEFoundationErrorDomain Code=1 "exportOptionsPlist error for key 'method': expected one of {app-store, ad-hoc, enterprise, development, validation}, but found ${IPA_EXPORT_METHOD}" UserInfo={NSLocalizedDescription=exportOptionsPlist error for key 'method': expected one of {app-store, ad-hoc, enterprise, development, validation}, but found ${IPA_EXPORT_METHOD}}
How can I get the archive:
$ xcodebuild -workspace CLI.xcworkspace -scheme CLI -sdk iphoneos -configuration AppStoreDistribution archive -archivePath $PWD/build/CLI.xcarchive
How can I get the IPA:
$ xcodebuild -exportArchive -archivePath $PWD/build/CLI.xcarchive -exportOptionsPlist exportOptions.plist -exportPath $PWD/build
Export Options Plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>compileBitcode</key>
<false/>
<key>destination</key>
<string>export</string>
<key>method</key>
<string>${IPA_EXPORT_METHOD}</string>
<key>provisioningProfiles</key>

<true/>
<key>teamID</key>
<string>XXXXXXXXX</string>
<key>thinning</key>
<string><thin-for-all-variants></string>
</dict>
</plist>
EDIT: I can define different exportOptionsPlists for different targets. This solves my problem but I want to achieve it with one plist file.
