Assembling a JAR for a custom source set

[Narco]

I`m trying to reuse this example:
build.gradle

task intTestJar(type: Jar) {
    from sourceSets.intTest.classes
}


I`m trying to do it from custom plugin so I have:

public class LibraryPlugin implements Plugin {
...
def void use (Project project, ProjectPluginsContainer projectPluginsHandler){
project.usePlugin('java')
...
project.task unitTestJar(type: Jar) {
            from project.sourceSets.unitTest.classes
        }
}
...
}


The gradle throws exception on evaluating:
* What went wrong:
A problem occurred evaluating project ':app'.
Cause: No signature of method: lv.ctco.scm.cs.LibraryPlugin.unitTestJar() is app
licable for argument types: (java.util.LinkedHashMap, lv.ctco.scm.cs.LibraryPlug
in$_LibraryBuild_closure3) values: [[type:class org.gradle.api.tasks.bundling.Ja
r], lv.ctco.scm.cs.LibraryPlugin$_LibraryBuild_closure3@10948cf]

How to reuse task type of other plugin?

The  'task taskName(...)' syntax you can only use from the build  
script. We do some underlying transformation to make this legal Groovy  
code.

What you can do in a plugin class like above is to use the 'normal' api:

project.tasks.add('unitTestJar', Jar).from  
project.sourceSets.unitTest.classes

We will improve this in the future. The above way of declaring a  
plugin will always be possible. But alternatively you will be able to  
simply declare another build script as a plugin where you can use all  
the syntactic sugar we provide for that.

I believe I am missing something but gradle gives an error. Tried with Test task and gave the same error:

* What went wrong:
A problem occurred evaluating project ':app'.
Cause: Could not find method add() for arguments [unitTestJar, class org.gradle.
api.tasks.bundling.Jar, lv.ctco.scm.cs.LibraryPlugin$_LibraryBuild_closure3@1e35
ecd] on task container.

My plugin:
project.sourceSets {
            unitTest {
                compileClasspath = project.sourceSets.main.classes + project.configurations.compile +
                        project.configurations.testCompile
                runtimeClasspath = project.sourceSets.unitTest.classes + project.sourceSets.main.classes +
                        project.configurations.compile + project.configurations.testRuntime
            }
        }

project.tasks.add('unitTestJar', Jar){
            from project.sourceSets.unitTest.classes
        }

Found the correct solution:
project.sourceSets {
            'test-unit' {
                compileClasspath = project.sourceSets.main.classes + project.configurations.compile +
                        project.configurations.testCompile
                runtimeClasspath = project.sourceSets.'test-unit'.classes + project.sourceSets.main.classes +
                        project.configurations.compile + project.configurations.testRuntime
            }
        }
       
        project.getTasks().add('testUnitJar', Jar.class)
        project.testUnitJar.from(project.sourceSets.'test-unit'.classes)
        project.testUnitJar.fileSet(dir: project.sourceSets.'test-unit'.classesDir)
        project.testUnitJar.appendix = 'test-unit'

        project.getTasks().add('testUnitTest', Test.class)
        project.testUnitTest.testClassesDir = project.sourceSets.'test-unit'.classesDir
        project.testUnitTest.classpath = project.sourceSets.'test-unit'.runtimeClasspath

Works nice, but I need to define almost every task attribute by hands. I was expecting that 'test-unit' folder will be mapped everywhere by default.

That would be good. Could you add a JIRA issue for this?

It is hard to define what I want. By adding new sourceSet user wouldn`t always want new tests. There may be anything else. So that means customly created tasks shouldn`t be somehow automatically reconfigured. I`m happy I got it how to create my own targets in plugins and let`s leave it as is for now.
