I have reported an issue with the org.grails.pluginsviews markup4.0.0-M3 plugin and it should have been fixed and merged: https://github.com/apache/grails-gradle-plugin/issues/428 Grails 7.0.0-M4 was released yesterday but I don't think a new version of the views-markup plugin was released?

I haven't tracked your particular issue but there is a new version of the grails-views-markup jar: https://repo1.maven.org/maven2/org/apache/grails/grails-views-markup/7.0.0-M4/

I am trying to apply the plugin, but I can't figure out what the id of the new plugin is? It used to be:

apply plugin: 'org.grails.plugins.views-markup'

But that is no longer valid, I tried changing it to Apache (multiple combinations) but that doesn't work either?...

apply plugin: 'org.apache.plugins.views-markup'

and adding to the classpath but no luck:

buildscript {

...

dependencies {

...

classpath "org.apache.grails:grails-views-markup:$grailsVersion"

}

...

}

do you have

mavenCentral()

in your

repositories

list?

Yes

I think you've found a bug

Ok, so the plugin id is:

apply plugin: "org.apache.grails.gradle.grails-markup"

And yes it looks af if ther is an issue...

https://github.com/apache/grails-forge/issues/594 https://github.com/apache/grails-core/issues/14804 I was surprised we didn't see this in grails-forge testing, but it didn't have test coverage for that feature

Thank you @James Fredley

FYI: We've merged an initial fix for the markup plugin as part of the gradle deprecation cleanup. I think there may still be issues here though. @Thomas Rasmussen if you have time to test the next snapshot build (https://github.com/apache/grails-core/actions/runs/15626261655/job/44021000936) it would be helpful. I posted to the grails-core ticket - if we can get the test project that was submitted working, we'll check it in as a functional test to prevent these issues going forward.

I no longer get this error:

Cannot invoke "org.gradle.api.provider.Property.convention(Object)" because "this.fileExtension" is null

Now I get this one (on a clean project from start.grails.org with the markup views plugin added):

demo/grails-app/views/object/_object.gml: 7: [Static type checking] - Cannot find matching method java.lang.Object#render(java.lang.String). Please check if the declared type is correct and if the method exists.
 @ line 7, column 1.
   g.render("object")
   ^
1 error

Something is not being initialized correct but I can't figure out why?...

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'markupViewResolver': Cannot resolve reference to bean 'smartMarkupViewResolver' while setting constructor argument

so you think the gml code is valid?

I think the gml is valid https://views.grails.org/latest/#_content_negotiation:~:text=2.8.2.%20Global%20Default%20Template

if you remove the @CompileStatic at the top, does it worK?

No, I also tried changing it in application.yml

grails:
  views:
    markup:
      compileStatic: false

i'll have to research this, will look this afternoon
