Error - null: InvocationTargetException - org.springframework.boot.logging.DeferredLog

Question

Spring Boot application with the spring-boot-devtools dependency does not start because of the following error:

An exception occured while running. 
null: InvocationTargetException: 
org/springframework/boot/logging/DeferredLog: 
org.springframework.boot.logging.DeferredLog

I saw that in the package org.springframework.boot: spring-boot-devtools:1.3.0.M5there is no class DeferredLog, but on the following Github's repository

https://github.com/spring-projects/spring-boot

it is present.

What is wrong? How to fix this error?

My best guess is that you are trying to use devtools with Spring Boot 1.2. You obviously can't do that.

If you want to use M5 upgrade your project to use Spring Boot 1.3.0.M5. You can do that by upgrading the version in the parent or change the version of the spring-boot-dependencies (if you're using Maven).

spring-boot-devtools:1.3.0.M5 required spring-boot 1.3.0 just change at pom.xml and mvn clean package

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.0.BUILD-SNAPSHOT</version>
</parent>

spring-boot-devtools 1.3.0.M5 does not require the snapshot to run. This is a milestone release so you should be able to just use tat.

I meant that the required version of the spring-boot 1.3.0 as only there appeared a class DeferredLog

your example should use 1.3.0.M5 then, not snapshot.
