Solution: 

If you get this exception, that means that you are using the earlier version than Spring 3.2 and missing the libraries for CGLIB. 

 Beginning Spring 3.2, all net.sf.cglib classes moved to org.springframework.cglib and inline them directly within the spring-core JAR. CGLIB is a Byte Code Generation Library is high level API to generate and transform Java byte code. It is a third part library now merged to the Spring framework itself.

java: You aren't using a compiler supported by lombok, so lombok will not work and has been disabled.

This will disable collection of dependencies specified by an annotation processor when Filer methods are called

Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.2.3.RELEASE:repackage failed: Unable to find main class

By
Solutions:  Solution 1 : You needed to change the packaging parameter to jar from pom. Also, the repositories , pluginRepositories , the maven-compiler-plugin and the spring-boot-maven-plugin's version and executions weren't needed. Solution 2:  Try mvn install and see if it works Solution 3: Preview: <properties> <!-- The main class to start by executing java -jar --> <start-class> com.mycorp.starter.HelloWorldApplication </start-class> </properties> Solution 4: Enable the main() method in your Application.java. Configure spring-boot-maven-plugin to specify the class with the main class (Spring should find it anyway if you have one, but good to be explicit): Preview: <plugin> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-maven-plugin </artifactId> <version> ${spring-boot-version} </version>...
