Hi all,

First of all, apologies if this isn't the right place to post this, I'm fairly new to the KIE Suite

I am running a Java EE web application and I'm having trouble compiling a bunch of .bpmn files that contain Java script nodes.

When I attempt to compile the flows, I get errors saying

Syntax error, <offending syntax> only available if source level is 1.5 or greater

I am using Java 1.8 and version 7.15.0 for .jar's related to Drools/jBPM/KIE

My project is structured with the .bpmn files inside src/main/resources and I have a kmodule.xml inside src/main/resources/META-INF/kmodule.xml

The contents of my kmodule are as followed:

<?xml version="1.0" encoding="UTF-8"?>
<kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule" />

I am then creating a KieSession object in the java code.

public KieSession getKieSession() {
  KieServices kieServices = KieServices.Factory.get();
  KieBaseConfiguration kieBaseConfiguration = kieServices.newKieBaseConfiguration();
  kieBaseConfiguration.setProperty("drools.dialect.java.lngLevel", "1.8");
  return kieServices.getKieClasspathContainer().newKieBase(kieBaseConfiguration).newKieSession();
}

Line 4 was my attempt at trying to set the Java language level, however this didn't work. I looked at the documentation here: KIE :: Public API 7.15.0.Final API

and it seems that property was for an older version (KnowledgeBuilderConfiguration (Knowledge API 5.2.0-SNAPSHOT API)), it doesn't exist anymore. My question is how do I configure KIE to compile using Java 1.8?
