Error creating bean with name 'gspTagLibraryLookup': ... No signature of method: static ... isConverterClass() is applicable for argument types: ... [class java.lang.Boolean]

[MMesch]

I have a grails 4.0 app that compiles fine with gradle but that fails when I deploy it on tomcat. I get plenty of BeanCreationExceptions that allows go back to a problem with isConverterClass (see below).

 nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gspTagLibraryLookup': Invocation of init method failed; nested exception is groovy.lang.MissingMethodException: No signature of method: static org.grails.web.converters.ConverterUtil.isConverterClass() is applicable for argument types: (Class) values: [class java.lang.Boolean]

I am quite new to grails and don't even know if this plugin is related to it. Any ideas?

Ran into this as well while upgrading to Grails 4. Make sure you add the dependency on the converters plugin to your build.gradle:

compile 'org.grails.plugins:converters:4.0.0'

Hey,

I'm also getting a similar error on start up of my Grails 4.0.4 application when running on Tomcat 8.5.57, Java version 1.8.0.241. This app is going through an upgrade from Grails 3.2.2.

10/08/2020 14:43:41.985 ERROR org.springframework.boot.SpringApplication - Application run failed groovy.lang.MissingMethodException: No signature of method: static org.grails.web.converters.ConverterUtil.isConverterClass() is applicable for argument types: (Class) values: [boolean] I've included the converters plugin in my build.gradle, using 4.0.1.

The application comes up fine when doing grails run-app, but when I go to install the WAR file into the webapps directory, I receive this error. If there is any other information you need that can help, please let me know.

Thank you.

EDIT: corrected version of converters plugin.

Did you manage to fix this? I'm seeing the same issue and don't have a solution yet.

Hi,

This turned out, in my case, to be a conflict in versions of the converter library. Check your dependency graph and look for older versions of the converters library, you may need to upgrade some other plugin.

Thank's @jasonwhetton. You gave me a good hint. dependency conflict
