Failed to execute goal org.springframework.boot:spring-boot-..:2.1.8. An exception occurred while running. null

I'm new into SpringMVC and got stuck here. I created a Spring Boot application through Spring Initializr and then created HomeController, connected it with index.jsp. It was working fine but when I added SearchController, connected with search.jsp, it dosen't work now. Before adding SearcController, the application was running fine but then it says:

Failed to execute goal ...plugin:2.4.0:run (default-cli) on project hplus : Application finished with exit code: 1

Update: after doing some searches I found out that my database's server was not running and after running that, and running my application as Test, I got this error.

Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set .

Full Error!
Test set:HplusappApplicationTests
<<< ERROR!
java.lang.IllegalStateException: Failed to load ApplicationContext

Solution After searching for more than two days, I found out it's the timeZone problem.

I edited application.properties, line two ->

spring.datasource.url=jdbc:mysql://localhost:3306/hplus?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false

https://stackoverflow.com/a/56537473/14623694

It solved the issue.

There seems to be error's when defining the bean and also your pom file, have you tried running a clean instal, with the

mvn clean instal

command? If that still doesn't work try to look at your pom and application.properties file is there still some mixed versions? If that still doesn't work try deleting your .m2 file and run the mvn clean install once again.

You need to specify the MySQL dialect Hibernate should use :

put this in application.properties:

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]

It clearly says that you entered a wrong mvn command. What is the command you executed? We generally run mvn clean install to build an application. Here is a list of Maven commands that might help you.
