bug: cannot add template sources when using the maven plugin

[SwithinCush]

How does one add template sources to the spoon template path when using the spoon maven plugin?

I am trying to build a project using spoon template processing, however I continually get an error saying that my template class is not part of the model and that I need to add it to the template sources, however there is no obvious way to do this. Please advise.

Thanks for your question.

It seems that templates are supported in spoon-maven-plugin but not documented.

$ ag template src/main/
src/main/java/fr/inria/gforge/spoon/util/TemplateLoader.java
10:public final class TemplateLoader {
13:	private TemplateLoader() {

src/main/java/fr/inria/gforge/spoon/SpoonModel.java
15:	private List<String> templates;
38:	public List<String> getTemplates() {
39:		return templates;
42:	@XmlElementWrapper(name = "templates")
43:	@XmlElement(name = "template")
44:	public void setTemplates(List<String> templates) {
45:		this.templates = templates;

So one may configure spoon-maven-plugin as follows: SpoonLabs/spoon-maven-plugin#64

@surli you're expert on this, WDYT?

I'm far from being an expert on this :) But AFAICS while crawling the source, the only way to make it work right now, is by using the following steps:

1. Create a folder called ``Spoon` (yes with the first letter uppercase...) and containing the template sources with the whole package hierarchy. This folder must be at the same location than where you execute the spoon-maven-plugin from what I understand. (see: https://github.com/SpoonLabs/spoon-maven-plugin/blob/master/src/main/java/fr/inria/gforge/spoon/util/TemplateLoader.java#L18)
2. Use a spoon.xml file at the same level as the Spoon folder, in which you specify a templates section with the template you wish to use, an example is available there: https://github.com/SpoonLabs/spoon-maven-plugin/blob/master/src/test/resources/fr/inria/gforge/spoon/unit/spoon.xml#L13

This should definitely be improved...

Thanks Simon for the explanation. Would you have a look at this?

Did you ever get a resolution for this issue? I am experiencing the same thing with version 8.4.0-beta-15.
