I want to create an executable jar-file with gradle & springboot. I have already cleaned gradle, reinstalled java and killed all the java processes. Sometimes the process also stopps at 80% and I am not able to access the command window anymore. I am a working on a Remote Desktop. 
But when I execute gradle bootRun the command line shows the following error message:
2015-12-11 13:20:55.133 ERROR 5992 --- [           main] o.s.boot.SpringApplicat

* What went wrong:

Here is my build.gradle file:
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.0.RELEASE")
    }
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'
jar {
    baseName = 'gs-rest-service'
    version =  '0.1.0'
}
repositories {
    mavenCentral()
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
    providedCompile("org.springframework.boot:spring-boot-starter-web")
    testCompile("junit:junit")
}
task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}
springBoot{
    mainClass = "DBConnection.Application"
}
And my Application.java file:
package DBConnection;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
    @SpringBootApplication
        public class Application {
            public static void main(String[] args) {
                SpringApplication.run(Application.class, args);
            }
        }
Thanks a lot! I really dont know what to do anymore..
