+++ This bug was initially created as a clone of Bug #1310261 +++

Description of problem:
When converting an .xls file to a GDT, globals defined in the spreadsheet are stored in a .gdrl file in the same package. However, if an update is made to values in the decision table and the project is built/deployed, applications running a kie-scanner will fail to deploy the kiebase with an error like the following:

ERROR o.d.c.k.b.impl.KieContainerImpl - Unable to update KieBase: defaultKieBase to release example:scanner-reproducer:1.11
Rule Compilation error : [Rule name='Whatever']
	defaultpkg/Rule_Whatever395648274.java (13:477) : list cannot be resolved

where 'list' is the global variable defined in the .gdrl file and referenced in the modified rule.


This behavior appears to apply to any rule referencing a global defined in a separate file. If the rule changes but the global file does not, the kiebase fails to compile.



How reproducible:
Always


Steps to Reproduce:
1. Create a new Global Variable file in business-central
2. Define a global variable
3. Create a new GDT, Guided Rule, or DRL file
4. Reference the global variable in the rule.
5. Configure a kie-scanner in a client application to load the LATEST version of the project
6. Update the rule (but not the global variable)
7. Increment the version in the projects pom.xml
8. Build/Deploy the project

Actual results:
ERROR o.d.c.k.b.impl.KieContainerImpl - Unable to update KieBase: defaultKieBase to release example:scanner-reproducer:1.11
Rule Compilation error : [Rule name='Whatever']
	defaultpkg/Rule_Whatever395648274.java (13:477) : list cannot be resolved

Expected results:
No error, kiebase updated with updated rules

Adding a simple reproducer scenario.

Steps to reproduce:

1. Import brms-project into brms workbench
2. Build/Deploy the project
3. Run client/src/main/java/example/Client.java
4. When prompted, update reproducerRule in workbench, then increment project version and Build/Deploy again
5. Press ENTER on the console where Client is waiting
6. Observe exception
