Description

The 2.6.0-alpha-1 jars have some incorrect service metadata.

To reproduce, create a gradle project containing the following files:

Calc.java

public class Calc {
    public static int sum(int a, int b) { return a + b; }
}

CalcTest.groovy

class CalcTest extends GroovyTestCase {
    void testSum() { assert 3 == Calc.sum(1, 2) }
}

build.gradle

group 'calc'
version '1.0-SNAPSHOT'

apply plugin: 'groovy'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.6.0-alpha-1'
    testCompile 'junit:junit:4.12'
}

When invoking the test task via gradle, the following error is observed:

:compileJava
error: Bad service configuration file, or exception thrown while constructing Processor object: javax.annotation.processing.Processor: Provider org.antlr.v4.runtime.misc.RuleDependencyProcessor not found
:compileJava FAILED

I believe we need to reference:
groovyjarjarantlr4.v4.runtime.misc.RuleDependencyProcessor
instead of:
org.antlr.v4.runtime.misc.RuleDependencyProcessor
in our jarjar'd jar files within this file:
META-INF/services/javax.annotation.processing.Processor

We might need to roll this by hand since I suspect we won't be able to configure the antlr gradle plugin to do such a change.
