I just downloaded the template for exercise 8 and have some problems.

"sbt eclipse" results in

Code: Alles auswählen

[error] Could not create Eclipse project files:
[error] [Error evaluating task 'scalacOptions': error,Error evaluating task 'externalDependencyClasspath': error,Error evaluating task 'update': error,Error evaluating task 'updateClassifiers': error,Error evaluating task 'updateClassifiers': error]

"sbt compile" also results in several errors.

Hi,

I've updated the template.
Alternatively you can remove the last two dependencies in build.sbt.

Best,

When using the annotation "TemplateMethod" I get compile issues. I'm using it like described in the exercise sheet / Readme.md:

Code: Alles auswählen

@TemplateMethod("<NAME_OF_A_PRIMITIVE_OPERATION>")
protected void <TEMPLATE_METHOD_NAME>() {...}

I also imported the Annotation interface via

Code: Alles auswählen

import de.tudarmstadt.stg.sedc.annotations.templateMethod.TemplateMethod

However, I get a compile error for each time I've put the TemplateMethod annotation:

Code: Alles auswählen

[warn]  <Path to file / Line of code> error: cannot find symbol
[warn]  @TemplateMethod("<NAME_OF_A_PRIMITIVE_OPERATION>")
error: annotation @TemplateMethod is missing a default value for the element 'primitiveOperationNames'
[warn]  @TemplateMethod("<NAME_OF_A_PRIMITIVE_OPERATION>")

I have already changed the dependencies in build.sbt
Somebody else has this problem and/or knows how to solve it?

Hi,

in Java the Syntax is a little bit different. You have to use the corresponding name of the field that is assigned, i.e. in this case:

Code: Alles auswählen

@TemplateMethod(primitiveOperationNames = "<NAME_OF_A_PRIMITIVE_OPERATION>")
protected void <TEMPLATE_METHOD_NAME>() {...}

Best,
