Question

when running the code below
i’m getting compilation error:
java: ..\JavaClass.java:8: cannot find symbol
symbol : method add(java.math.BigDecimal)
location: class BigDecimalDelegated

it seems like the stub of the groovy class created for the java compiler does not contain the delegated methods.

any idea?

consider this classes:

class BigDecimalDelegated  //groovy class
{
    @Delegate BigDecimal delegated;
    String data;
}

import org.junit.Test;
import java.math.BigDecimal;
public class JavaClass  //java class
{
    @Test
    public void temp()throws Exception
    {
        new BigDecimalDelegated().add(BigDecimal.TEN);
    }
}

Groovy compiler used in IDEA’s external build doesn’t support this, see https://issues.apache.org/jira/browse/GROOVY-4647

You can either use @Delegate classes from Groovy code only, or switch off external build in Settings | Compiler to use the old build mechanism.
