After upgrading to Gradle 2.0: Could not find property 'Compile' on root project

For Groovy based projects. It'd be:

tasks.withType(GroovyCompile) {
    options.debug = true
}

Use task.withType(JavaCompile).

My code:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.bmuschko:gradle-tomcat-plugin:2.2.3'
    }

  tasks.withType(JavaCompile) {
      options.debug = true
      options.debugOptions.debugLevel = "source,lines,vars"
      options.encoding = "UTF-8"
  }
}

Changing the line to

tasks.withType(JavaCompile) { options.encoding = "UTF-8" }

fixed the issue.
