Run-time error on using stardog-groovy: no class found -> com.clarkparsia.stardog.StardogException

[fra...@gmail.com]

Hi,

I wrote the following code with eclipse (+ groovy plugin):

import com.clarkparsia.stardog.ext.groovy.*;

class MyGreetings2 {

static void main (def args)

{

def s = new Stardog();

}

}

I added the folder lib of stardog1.2 and the jars of stardog-groovy and stardog-spring for stardog 1.2.

When I run as a script my groovy code, the following error occurs:

Caught: java.lang.NoClassDefFoundError: com/clarkparsia/stardog/StardogException

java.lang.NoClassDefFoundError: com/clarkparsia/stardog/StardogException

at MyGreetings2.main(MyGreetings2.groovy:9)

Caused by: java.lang.ClassNotFoundException: com.clarkparsia.stardog.StardogException

... 1 more 

Can someone help me?

Thank you.

If you are running this from Eclipse, how are the jars visible to the classpath?

Did you add them manually via Eclipse's buildpath, or via the Gradle Eclipse plugin, or something else?

FYI, the Gradle Eclipse plugin can be found here: https://github.com/SpringSource/eclipse-integration-gradle/

I'm using Eclipse's buildpath.

The jars I included are:

.. I have similar errors by using groovysh and GroovyConsole

Adding external class folders like that does not appear to work, at least in Eclipse Juno.  If you expand the 'lib' folder, you'll see all the jar files do not have the little jar icon next to them and are in fact - not on the classpath.

You might want to just do a find/xargs, pull all the jar files into a single folder and then import external jars in the Eclipse build path.

Thank you very much Al,

I wrote a groovy script :) to copy jars into one folder and updated eclipse build path. It works :)
