Issue in running Spock Spec from within Eclipse

[Icarus]

Hi,

I am using Spock framework from within eclipse ( I downloaded the jar
- spock-core0.6-groovy-1.7 SANPSHOT jar )
and am using that with a Java project that I converted to a Groovy
Project.

I am trying to test some existing Java Classes from this Groovy
Project.

However, I am not able to run the project as it complains -
"java.lang.NoSuchMethodError: main
Exception in thread "main" .

Are there some intermediate steps that I am missing ?


Thanks,

Arun

Without more information (Eclipse version, stack trace, example project, etc.), it's impossible to say what the problem is. The general steps for using Spock with Eclipse are explained here: http://code.google.com/p/spock/wiki/GettingStarted#Eclipse

Cheers,

Peter

Hey Arun,

Have you tried the groovy eclipse plugin mailing list? If you're out
of options you could try having Gradle generate your eclipse project.
If it's a classpath/dependency issue that would fix it:

------ build.gradle ------
apply plugin: 'groovy'
apply plugin: 'eclipse'

repositories {
mavenCentral()
}

dependencies {
groovy 'org.codehaus.groovy:groovy-all:1.7.6'
testCompile 'org.spockframework:spock-core:0.5-groovy-1.7'
}
------ build.gradle ------
Once you have gradle installed, execute "gradle eclipse" from the
command-line.

Cheers,
Merlyn

Hi Peter,

Here are the details of my installation and the steps I am taking :

Eclipse : Helios (20100617-1415)
Groovy Eclipse plugin : v2.1.2

Following Libraries have been added to the project:
- Groovy Libraries
- groovy-all-1.7.5.jar and remaining
ones for commons, ivy, jline and servlet-api
- JRE System Libraries
- JUnit 4

Referenced Library :
- spock-core-0.5-groovy-1.7.jar

Specification


class WorkflowTest extends spock.lang.Specification{


def "testing simple Spock Method"(){
expect:
name.size() == length
where:
name << ["Kirk", "Spock", "Scotty"]
length << [4,5,6]
}
}

When I try running the class as a JUnit Test, I get following error :

Class not found com.iconsole.test.WorkflowTest
java.lang.ClassNotFoundException: com.iconsole.test.WorkflowTest
at java.net.URLClassLoader$1.run(Unknown Source)

Seems like the class file is not being generated. Am I missing some
step ?

Thanks,
Arun

Hi Merlyn

I used the gradle file to generate a sample project. But still
getting the class not found error.

Class not found com.arun.test.SampleTest
java.lang.ClassNotFoundException: com.arun.test.SampleTest

Thanks for helping... but it seems I am missing some step for
generating the test class.

Ok. Great. Next step is to check with the eclipse plugin user mailing list.

[Peter Niederwieser]

Seems like the spec doesn't get compiled. Does a clean build produce errors? Is there anything suspicious in the Eclipse log?

Cheers,

Peter

Hi,

The issue was with my Class File. I was missing a package ...
statement.

Adding that statement allowed me to run the test.

Thanks,
Arun
