.GroovyCastException Exception when using GrettyStartTask about gretty

[akhikhl]

Issue is well-reproducible, I'll try to fix it.

OK, here is the solution. Replace the line:

apply from: 'https://raw.github.com/akhikhl/gretty/master/pluginScripts/gretty7-0.0.17.plugin'

with:

apply plugin: 'gretty7'

and then error is gone.

Source of the problem seems to be the following: as soon as you include gretty-plugin twice (once in buildscript and again in "grettyX-0.0.X.plugin"), gradle gets confused and cannot load classes properly.

General recommendation:
If you use apply-from '... grettyX-0.0.X.plugin', then you don't need classpath for gretty in buildscript, since .plugin file already does it for you.
Of course, you are not obliged to use apply-from, you can do apply-plugin instead.
I'll update usage section in wiki on this.

thanx for solution. but i needed to use classpath in buildscript because otherwise gradle didn't find the GrettyStartTask class at all.

[akhikhl]

Ah, I understand. Yes, when you do "apply-from", importing the package does not work. I don't know why - it looks like deficiency/bug in gradle.

The complete working solution for you:

import org.akhikhl.gretty.*

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'org.akhikhl.gretty:gretty7-plugin:0.0.17'
  }
}

repositories {
  mavenCentral()
}

apply plugin: 'gretty7'

task ('jettyRunForIntegrationTest', type: GrettyStartTask) {
  integrationTest = true
}
