i want run gradle java ee project using netbeans on ubuntu 12.04. error - project output:

build failure: gradle run org.gradle.tooling.buildexception: not execute build using gradle distribution   'http://services.gradle.org/distributions/gradle-1.7-bin.zip' 

my gradle -version output:

and build.gradle file:

apply plugin: 'java' apply plugin: 'war' mainclass = "main.main"  sourcecompatibility = '1.7' [compilejava, compiletestjava]*.options*.encoding = 'utf-8' if (!hasproperty('mainclass')) {     ext.mainclass = 'main.main' }  repositories {     mavencentral() }  dependencies {     compile group: 'org.hibernate', name: 'hibernate-core', version: '3.6.7.final'     compile group: 'org.hibernate', name: 'hibernate-entitymanager', version: '3.6.7.final'     compile "javax.ws.rs:jsr311-api:1.1.1"     compile 'com.sun.jersey:jersey-server:1.13'     compile 'com.sun.jersey:jersey-core:1.13'     compile 'com.sun.jersey:jersey-servlet:1.13'     testcompile group: 'junit', name: 'junit', version: '4.10' } 

this error occurs when i'm trying use hibernate (create entitymanager): netbeans log:

slf4j: failed load class "org.slf4j.impl.staticloggerbinder". slf4j: defaulting no-operation (nop) logger implementation slf4j: see http://www.slf4j.org/codes.html#staticloggerbinder further details. exception in thread "main" javax.persistence.persistenceexception: no persistence provider entitymanager named websismspupgsql @ javax.persistence.persistence.createentitymanagerfactory(persistence.java:69) @ jpa.entitymanagerfactory.reinit(entitymanagerfactory.java:69) @ jpa.entitymanagerfactory.<init>(entitymanagerfactory.java:61) @ jpa.entitymanagerfactory.<init>(entitymanagerfactory.java:56) @ jpa.entitymanagerfactory.getinstance(entitymanagerfactory.java:43) @ main.main.main(main.java:18) :run failed  failure: build failed exception.  * went wrong: execution failed task ':run'. > process 'command '/usr/lib/jvm/jdk1.7.0_25/bin/java'' finished non-zero exit value 1
