How to get rid of StringTemplate warning "\n in string" - stringtemplate

Question

I'm using StringTemplate 4 to generate some Java source files.
The templates are really simple, e.g.:
QueryHandler(method) ::="
public class Obtenir<method.name>Handler extends QueryHandler\<List\<<method.name>Db>> implements IQueryHandler\<List\<<method.name>>>{
private IQuery\<List\<<method.name>Db>> query;
private <method.name>Converter converter;
#Inject
public Obtenir<method.name>Handler(IQuery\<List\<<method.name>Db>> query, <method.name>Converter converter, IStatisticsCollecter theStatsCollecter){
super(theStatsCollecter);
if(query == null){
throw new IllegalArgumentException(\"The query argument cannot be null\");
}
if(converter == null){
throw new IllegalArgumentException(\"Illegal argument for converter(null)\");
}
this.query = query;
this.converter = converter;
}
public List\<<method.name>> handle(Object... params) throws JdbcException {
final String method = \"obtenir<method.name>\";
DaoQueryStatusCallable status = new DaoQueryStatusCallable();
List\<<method.name>Db> result = invoke(query, status, method);
return converter.convert(result);
}
}
"
The code is even simpler:
STGroup group = new STGroupFile("src/main/resources/QueryHandler.stg");
ST wsTemplate = group.getInstanceOf("QueryHandler");
wsTemplate.add("method", m);
System.out.println(wsTemplate.render());
The template lines are separated by Unix EOLs (\n).
When I execute the code, StringTemplate is emitting a warning "QueryHandler.stg 1:25: \n in string".
The result is correct, but I'd still like to get rid of this message.
Anybody ever had this problem and knows how to solve it?

Answer 1

t() ::= "..." is meant only for single lines. Please use
t() ::= <<
...
>>
to get multi-line templates.
