Compiled classes have missing package declaration. about rocker HOT 8 CLOSED

No, rocker definitely creates package names. You are most definitely
missing a property the generator process resulting in no package
declaration. There are 3 properties that must be set for Rocker to figure
out what you meant as the package name.

You should set output directory & template directory.

If you send me your project structure and what you're setting the config to
I can help pinpoint it. If its like your answer to gradle, then what are
you putting your views in?

E.g. src/main/resources --> the package name detection would start from
inside resources. So you'd need to put your template in
src/main/resources/views/my.rocker.html for a package of "views" to be
calculated.

Thanks for your quick reply, yes indeed I'm using gradle although in a different way as explained on my gradle post.

Here is what I'm doing:

1. I have custom gradle plugin which is an independent jar, this file contains a method that uses your generator to compile the templates. This method is exposed as a gradle task to any project using the plugin.

public static void compileRockerTemplates(String rockerTemplateDirectory, String rockerOutputDirectory, String rockerClassDirectory) {
    try {

      JavaGeneratorMain jgm = new JavaGeneratorMain();

      File templateDirectory = new File(rockerTemplateDirectory);
      File outputDirectory = new File(rockerOutputDirectory);
      File classDirectory = new File(rockerClassDirectory);

      jgm.getParser().getConfiguration().setTemplateDirectory(templateDirectory);
      jgm.getParser().getConfiguration().setOutputDirectory(outputDirectory);
      jgm.getGenerator().getConfiguration().setClassDirectory(classDirectory);

      jgm.setFailOnError(true);

      jgm.run();

    } catch (Exception ex) {
      Logger.getLogger(Extras.class.getName()).log(Level.SEVERE, null, ex);
    }

2. I use the plugin in my main project with the following config that will get passed to the compileRockerTemplates method.

rockerTemplateDirectory = project.projectDir.toString() + '/src/main/java/com/joe/view/template'
rockerOutputDirectory = project.projectDir.toString() + '/src/main/java/com/joe/view/template'
rockerClassDirectory = project.projectDir.toString() + '/src/main/java/com/joe/view/template'

with the following template inside the template folder

@args (String world)

<!DOCTYPE html>
<html>
  <head>
    <title>TODO supply a title</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
  </head>
  <body>
    <div>@world</div>
  </body>
</html>

When I call my compileRockerTemplates task templates get compiled as expected

3. The template is finally rendered inside a JAXRS method to expose it to the web client.

@Stateless
@Path("test")
public class TestVIEW {

  @GET
  public String testView(){
    return TestTemplate.template("Hello World!")
    .render()
    .toString();
  }

}

The only problem is that the generated TestTemplate.java lacks the package declaration, if I manually add it everything works as expected, I was considering to add it myself on the compileRockerTemplates method modifying the files but maby as you point out I'm missing something that I should intialize on JavaGeneratorMain

Many thanks for your help and advise.

from rocker.

Simple fix. The base template directory is base dir where the package is
calculated from. If you wanted your final package to be "view.template"
then you'd just need to change the settings to:

rockerTemplateDirectory = project.projectDir.toString() +
'/src/main/java/com/joe'
rockerOutputDirectory = project.projectDir.toString() + '/src/main/java/com/joe'
rockerClassDirectory = project.projectDir.toString() + '/src/main/java/joe'

Or to be a java package of 'com.joe.view.template' then:

rockerTemplateDirectory = project.projectDir.toString() + '/src/main/java'
rockerOutputDirectory = project.projectDir.toString() + '/src/main/java'
rockerClassDirectory = project.projectDir.toString() + '/src/main/java'

However, I'm not familiar with gradle, but I'm guessing there's a
better standard directory to put your generated sources? Polluting
your src/main/java with them may not be the best practice. In maven,
the default directory is something like
target/generated-sources/rocker. Most IDEs also pick up that
directory so code completion, etc. works.

The class directory is definitely wrong. That should be set to the
place your .java files are compiled to. Again in maven, that would be
something like target/classes.

Nice, I solved the issue with your advise.
Testing with the paths, I found that I can keep the templates inside the "src/main/resources/" plus the same structure where i want the files to be output on "src/main/java"

so in my case i'll place the templates on "src/main/resources/com/jo"
so that the java files output to "src/main/java/com/jo"
with the correct package

I achive this with the following configuration.

 rockerTemplateDirectory = project.projectDir.toString() + '/src/main/resources'
 rockerOutputDirectory = project.projectDir.toString() + '/src/main/java'
 rockerClassDirectory = project.projectDir.toString()

I placed the rocker-compiler.conf on the project root since I'm on a web project and theres no target, the only option to place it where compiled classes are would be to place it on "src/main/webapp/WEB-INF" but I'm not sure why is the rocker-compiler.conf file needed on a web project.

Thank you very much for your help, this issue is closed for me, hope it helps other gradlers out there.

from rocker.

Great. Sounds like a nice solution. Any interest in submitting a PR for the README.md that shows how to use Rocker generator from Gradle?

from rocker.

Sure if not a PR ill PM you the code ^_^, just need to fix the other issue#36 with BindingRockerModel to make sure everything is working.

from rocker.

I've uploaded a working rocker build.gradle to issue#33 with a downloadable example project, so this can serve as groundwork for a future gralde-rocker-plugin and readme documentation.
