Hi Gradle Experts,

I am struggling to debug while developing the custom plugin on sts eclipse ide. They provided some jars in the sts gradle plugin. commons-collections-3.2.1.jar commons-collections-3.2.1-sources.jar gradle-base-services-1.2.jar gradle-core-1.2.jar gradle-core-1.2-sources.jar gradle-messaging-1.2.jar gradle-tooling-api-1.2.jar gradle-tooling-api-1.2-sources.jar gradle-wrapper-1.2.jar gradle-wrapper-1.2-sources.jar guava-11.0.2.jar jsr305-1.3.9.jar plugins README.txt slf4j-api-1.6.6.jar slf4j-simple-1.6.6.jar slf4j-simple-1.6.6-sources.jar

But while creating custom instance plugin as

final Project project = ProjectBuilder.builder().build()

the error coming like this

Exception in thread “main” org.gradle.api.internal.classpath.UnknownModuleException: Cannot locate JAR for module ‘gradle-core-impl’ in distribution directory ‘E:\Users\pramesh\Downloads\springsource\sts-3.1.0.RELEASE\plugins\org.springsource.ide.eclipse.gradle.core_3.1.0.201210040512-RELEASE’.

Why it is expecting gradle-core-imp in that location, actually it was not there it’s class path. Otherwise i can locate the Gradle installation folder to eclipse to access the libraries. But in their distribution also the module is not there.

Please help me on this.

You’ll have to ask the Eclipse folks. For some reason Gradle thinks it’s running from a distribution at ''E:\Users\pramesh\Downloads\springsource\sts-3.1.0.RELEASE\plugins". This is pretty strange.

Is this source open that I can take a look at it?

Please see the code what am doing wrong. {

package com.cordys.tools.mb.gradle

import org.gradle.api.* import org.gradle.testfixtures.ProjectBuilder;

class MbvPlugin implements Plugin {

private MbvPluginExtention extention

@Override

public void apply(Project project) {

extention = project.extensions.create(‘mbv’, MbvPluginExtention, project)

project.task(‘mbvMain’, type :MbvMain).with {

srcFolder = extention.srcFolder

showLines = extention.showLines

ignoreMarker = extention.ignoreMarker

violationsFile = extention.violationsFile

outFile = extention.outFile

}

project.tasks.findByName(“mbvMain”).doFirst {

//Deleting the mbv folder

project.delete(‘build/reports/mbv’)

//making directory in project folder

project.mkdir(‘build/reports/mbv’)

}

}

static main(args){

final Project project = ProjectBuilder.builder().build()

project.apply(plugin : ‘mbv’)

assert project.tasks.findByName(‘mbvMain’)

}

}

I can only guess that you are somehow getting Gradle from the Eclipse plugin in your runtime path. How are you getting the Gradle jars on your classpath?

Hi Luke, Eclipse gradle plugin itself pointing to the jars which are provided by them. \springsource\sts-3.2.0.RELEASE\plugins\org.springsource.ide.eclipse.gradle.core_3.2.0.201303060652-RELEASE\lib\*.jar

They only ship the Jars necessary to run the Tooling API. You need the runtime jars.

I can’t recommend how to fix this as I don’t understand your project setup.
