Gradle task not able to resolve class

Help/Discuss
1

Hi all. I have a gradle (1.8) project with 2 classes A and B where B import A. Both files are under /foo/bar/ package (myProjectFolder/test/foo/bar folder).

A.groovy class

package foo.bar

import org.junit.Test;

public class ATest{ 
    @Test
    public void run() {
        System.out.println("CLASS A");
    }
}

B.groovy class

package foo.bar

import org.junit.Test;

public class BTest{
    @Test
    public void run() {
        ATest a = new ATest();
        a.run();
        System.out.println("CLASS B");
    }
}

My build.gradle file

apply plugin: "groovy"
apply plugin: "java"

repositories {
        mavenCentral()
}

dependencies {
        groovy group: "org.codehaus.groovy", name:"groovy-all", version: "1.8.6"
        testCompile "junit:junit:4.10"
}

test {
        testLogging.showStandardStreams = true
}

sourceSets {
        test { groovy {
                srcDir 'test/foo/bar'
        } }
}

buildscript {
        repositories { mavenCentral() }
}

configurations{
    addToClassLoader
}

dependencies {
    addToClassLoader "junit:junit:4.10"
}

URLClassLoader loader = GroovyObject.class.classLoader
configurations.addToClassLoader.each {File file ->

loader.addURL(file.toURL())
}

task runA << {
    new GroovyShell().run(file('test/foo/bar/ATest.groovy'));
}

task runB << {
    new GroovyShell().run(file('test/foo/bar/BTest.groovy'));
}

So, what am I missing to run the task runB correctly?

Hi Ulisses,

I cannot help you understanding why GroovyShell does not find the other class but if what you’re trying to accomplish with runB is to execute just a subset of the tests may I suggest you to define a Test task instead?

task runB(type: Test) {
  classpath = sourceSets.test.runtimeClasspath
  testLogging.showStandardStreams = true
  include '**/B*'
}

This definition comes with the usual benefits of up-to-date checking, reporting, etc.

Cheers!
Rodrigo

It solves my problem, but not the GroovyShell issue.
Still don’t know why GroovyShell can’t find class A.

I will use your suggestion while I can’t fix GroovyShell.
Obrigado jovem.
