Solutions :


Same Problem occur with me once below are the steps i follow.
Solution 1 :

  • I went to project > properties > javaBuildPath.
  • There In order of export , I moved up my java/main to the top priority.


Solution 2 :
  • Go to run configurations: - run->run configurations
  • In the Classpath tab: Select Advanced
  • Add where Eclipse usually put the *.class for the projects, which is in bin. So I added the bin directory for the project.

Solution 3 :

  • Project -> Clean
  • Make sure Project -> Build automatically is active
  • Project -> Properties -> Java Build Path -> Libraries: Remove any external libs you have ever added. Don't remove standard libraries like the JRE System Library.
  • Try to run your main class now. The "class could not be found / load" error should be gone. Try adding your external libs/jars one after each other.

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

By
  In order to make projects compile with the existing builds of Lombok processor, as a workaround you can use the flag -Djps.track.ap.dependencies=false which should be added to File | Settings | Build, Execution, Deployment | Compiler | Build process VM options field. 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>...
