How to pass parameters to a plugin during apply?

Ok, enough of those simplified examples, here is my actual stuff:

Plugin:

p ackage org.camunda.bpm.spring.boot.gradle;

import org.gradle.api.Plugin
import org.gradle.api.Project

class CamundaWebjarPlugin implements Plugin<Project> {

  void apply(Project project) {
    def myExt = project.extensions.create("camundaWebjarPlugin", CamundaWebjarPluginExtension)

    project.configurations {
      camundaEE
    }

    project.dependencies {
      camundaEE "org.camunda.bpm.webapp:camunda-webapp-ee-plugins:$myExt.camundaVersion@war"
      compile "org.camunda.bpm.webapp:camunda-webapp-ee-plugins:$myExt.camundaVersion:classes"
    }

    project.task("resolveCamundaEnterpriseWebjar") {
      dependsOn: project.configurations.camundaEE

      doLast {
        project.copy {
          from project.configurations.camundaEE.collect { project.zipTree(it) }
          into "$project.buildDir/resources/main"
        }

        project.delete "$project.buildDir/resources/main/META-INF"

        project.copy {
          from "$project.buildDir/resources/main/WEB-INF/securityFilterRules.json"
          into "$project.buildDir/resources/main"
        }

        project.delete "$project.buildDir/resources/main/WEB-INF"
      }
    }
  }
}

class CamundaWebjarPluginExtension {
  String camundaVersion = "23.5.6"
}

build.gradle:

buildscript {
  repositories {
    mavenLocal()
    mavenCentral()
  }

  dependencies {
    classpath 'org.camunda.bpm.extension.springboot.gradle:camunda-bpm-spring-boot-webjar-gradle-plugin:2.1.0-SNAPSHOT'
  }
}


plugins {
  id "java"
  id "org.springframework.boot" version "1.5.2.RELEASE"
  id "io.spring.dependency-management" version "1.0.1.RELEASE"
}

apply plugin: 'camunda-webjar-plugin'

camundaWebjarPlugin {
  camundaVersion = '7.6.3-ee'
}

repositories {
    mavenLocal()
    mavenCentral()
    maven {
        credentials {
            username camundaRepoUser
            password camundaRepoPassword
        }
        url 'https://app.camunda.com/nexus/content/repositories/camunda-bpm-ee'
    }
}

dependencyManagement {
    imports {
        mavenBom 'org.camunda.bpm.extension.springboot:camunda-bpm-spring-boot-starter-bom:2.0.0'
    }
    imports {
        mavenBom 'org.springframework.boot:spring-boot-dependencies:1.4.4.RELEASE'
    }
    imports {
        mavenBom 'org.camunda.bpm:camunda-bom:7.6.3-ee'
    }
}

dependencies {
    compile 'org.camunda.bpm.extension.springboot:camunda-bpm-spring-boot-starter-webapp-core'
    compile 'com.h2database:h2'

    testCompile 'junit:junit:4.11'
}

jar.dependsOn resolveCamundaEnterpriseWebjar

I tried what you proposed, but without any effect…
