Another user chimed in on SO and provided this answer that appears to work
in all test scenarios, even nested template scenarios:
String basic = "<%" +
" def mc1=testInstance.&test;" +
"println \"mc1 class ${mc1.getClass()}\";" +
"println \"mc1 metaclass ${mc1.getMetaClass()}\";" +
"println mc1.getClass();" +
"mc1();" +
"mc1('var1');" +
"mc1('var1', 'var2');" +
"testMethod();" +
"testMethod('var1');" +
" %>";
TemplateEngine engine = new GStringTemplateEngine();
TestMethodClass instance = new TestMethodClass();
// Prepare binding map
Map<String, Object> bindings = new HashMap<>();
bindings.put("testInstance", instance);
Template t = engine.createTemplate(basic);
Closure<?> make = (Closure<?>) t.make(bindings); // cast as closure
int resolveStrategy = make.getResolveStrategy();
make.setResolveStrategy(Closure.OWNER_FIRST);
// set method closure which you want to invoke directly (without .
// notation). This is more or less same what you pass via binding map
// but too verbose. You can encapsulate this inside a nice static
// method
InvokerHelper.setProperty(make.getOwner(), "testMethod", new
MethodClosure(instance, "test"));
make.setResolveStrategy(resolveStrategy);
String result = make.toString();
