dcdh opened a new issue, #6357:
URL: https://github.com/apache/incubator-kie-drools/issues/6357
**Current behavior**
I've got this kind of rule unit **rules.drl** inside my resource folder
```drl
package org.acme;
unit HomeRuleUnitData;
import org.acme.*;
declare Person
name : String
end
rule "No lights on while outside"
when
$l: /lights[ powered == true ];
not( /smartphones );
then
alerts.add(new Alert("You might have forgot one light powered on: " +
$l.getName()));
end
query "AllAlerts"
$a: /alerts;
end
rule "No camera when present at home"
when
accumulate( $s: /smartphones ; $count : count($s) ; $count >= 1 );
$l: /cctvs[ powered == true ];
then
alerts.add(new Alert("One CCTV is still operating: " + $l.getName()));
end
```
When I want to inject a **KieRuntimeBuilder** because I want to fire
programmatically another rules from a decision table it fails because no bean
is present.
**Expected behavior**
I may intend to trigger rules from different way. But maybe I am wrong and
it is not possible to do it this way.
**Additional information**
The implementation of KieRuntimeBuilder is automatically generated from the
**drools-model-codegen**
The generation is done via
https://github.com/apache/incubator-kie-drools/blob/85e510fb18681f82a6595769730dba47488fc68d/drools-model/drools-model-codegen/src/main/java/org/drools/model/codegen/project/KieSessionModelBuilder.java#L59C32-L59C40
This bloc code will not generate it if at least one rule unit is detected
https://github.com/apache/incubator-kie-drools/blob/85e510fb18681f82a6595769730dba47488fc68d/drools-model/drools-model-codegen/src/main/java/org/drools/model/codegen/project/RuleCodegen.java#L79
```java
if (!droolsModelBuilder.hasRuleUnits()) {
if (kieBaseModels != null) {
if (hasKieModule(context.getAppPaths().getPaths())) {
LOGGER.warn("The Kie Module configuration has been
provided externally, so the existing kmodule.xml file will be ignored.");
}
generatedFiles.addAll(new KieSessionModelBuilder(context(),
droolsModelBuilder.packageSources(), kieBaseModels).generate());
} else {
KieSessionModelBuilder kieSessionModelBuilder = new
KieSessionModelBuilder(context(), droolsModelBuilder.packageSources());
generatedFiles.addAll(kieSessionModelBuilder.generate());
this.kieBaseModels =
kieSessionModelBuilder.getKieBaseModels();
}
}
