Brongniart Jérôme created GROOVY-8708:
-----------------------------------------
Summary: SyntaxException when extending groovy.lang.Script
Key: GROOVY-8708
URL: https://issues.apache.org/jira/browse/GROOVY-8708
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 2.3.0
Reporter: Brongniart Jérôme
We are facing an issue when using the following groovy script is used as a
ScriptBaseClass with version 2.3.0 or greater:
{code:java}
abstract class Templates extends Script {
def test() {
def a = [];
return a;
}
}
{code}
Error:
{noformat}
Script1.groovy: 1: A transform used a generics containing ClassNode Templates
for the super class Script1 directly. You are not supposed to do this. Please
create a new ClassNode referring to the old ClassNode and use the new ClassNode
instead of the old one. Otherwise the compiler will create wrong descriptors
and a potential NullPointerException in TypeResolver in the OpenJDK. If this is
not your own doing, please report this bug to the writer of the transform.
{noformat}
The error happens when calling the following example (This example is working
as expected when using Groovy 2.2.2):
{code:java}
import java.io.IOException;
import org.codehaus.groovy.control.CompilationFailedException;
import org.codehaus.groovy.control.CompilerConfiguration;
import groovy.lang.GroovyShell;
import groovy.lang.Script;
public class GroovyTest {
public static void main(String[] args) throws
CompilationFailedException, IOException {
CompilerConfiguration groovyCompilerConfiguration = new
CompilerConfiguration();
groovyCompilerConfiguration.setScriptBaseClass("Templates");
groovyCompilerConfiguration.setDebug(true);
groovyCompilerConfiguration.setVerbose(true);
GroovyShell shell = new
GroovyShell(groovyCompilerConfiguration);
Script script = shell.parse("print \"test\"");
}
}
{code}
If this an issue from Groovy or is this change expected?
Thanks and regards
