Spring Boot Application failed to start with classpath:

I generated a Spring Boot application with jHipster, added some code from my previous project (non-jhipster project) and tried to run it using IDEA. First I got an error message similar to this, saying "Command line is too long.." (I am running Windows 10 x64). I clicked enable, but then I got an error like this.:

I posted my pom.xml here.

pom.xml

I created a completely new project, and started adding the maven dependencies I had one by one and Ran the project after every step. The problem with the classpath occurs, when I add BOTH spring-batch and guava to the pom.

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-batch</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>${guava-core.version}</version>
</dependency>


mvn clean install

mvn spring-boot:run

I had this same problem in a jHipster application with the same error messages and for me the root cause for me was wrong formatting (indentation) of spring mail settings in application-dev.yml. I just copy/pasted the settings from another project and IntelliJ indented them a bit differently than they were in original code and because of that they could not be resolved.

Those "manifest attribute" things appear every time when starting the application but at least for me they were not related to the real issue. Hope this helps to get to the root of the cause! Cheers,

This error message is output by
ClasspathLoggingApplicationListener#onApplicationEvent

But it does not output the real reason of the error.

So, you should start your app in debug mode, and add a breakpoint at this line, then you can check event.exception, and find out what is the real error happened.

event.exception

This problem wasted me like 30 minutes.... Hope this answer can save someone a little time

I had the same issue with jhipster @4.10.2 & the solution what I got is here,

jhipster @4.10.2

As @koni123 rightly said it is something to do with application-dev.yml, when i compared this file with the previous file version found that "spring.jpa.hibernate.format_sql: true" was giving me issue. Once i removed it from application-dev.yml it resolved my problem. Hope this helps.

application-dev.yml
