It can be a little difficult to answer without any element; if you have any fancy stuff please highlight or share your application better, but basically I was able to get it working with the following:
the build.gradle file was similar to your
apply plugin: 'spring-boot' sourceCompatibility = 1.5 version = '1.0' buildscript { repositories { jcenter() } dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.6.RELEASE") } } springBoot { mainClass = "com.readinglist.ReadingListApplication" } repositories { mavenCentral() } dependencies { compile("org.springframework.boot:spring-boot-starter-web") compile files('lib/selenium-server-standalone-2.47.1.jar') testCompile('org.springframework.boot:spring-boot-starter-test') }
I don’t know if they differ from each other, but the document is for version 1.2.6 http://docs.spring.io/spring-boot/docs/1.2.6.RELEASE/reference/html/build-tool-plugins- gradle-plugin.html # build-tool-plugins-gradle-dependencies-without-versions , and they mention to add dependencies.
A note on your script, not selenium, just needed for your testing? you can change compile files ..selenium to testCompile files ..selenium (or even testRuntime ), your jar file will thank you for that.
For information, I am creating a fairly basic Spring-Boot application for this testing (based on an example from Spring Boot In Action)
package com.readinglist; import org.apache.log4j.Logger; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.openqa.selenium.server.SeleniumServer; @SpringBootApplication public class ReadingListApplication { private static Logger log = Logger.getLogger(ReadingListApplication.class); public static void main(String[] args) { SpringApplication.run(ReadingListApplication.class, args); log.info("SeleniumServer ClassName is " + SeleniumServer.class.getName()); } }
The important part is to make sure you have a valid main method
For reference, my gradle execution

If something is wrong with you, make sure you do gradle clean after making some changes.
