Unable to package my Spring boot application as a runnable fat Jar

Question

I am a bit new to Spring boot and below is my application's POM/Java file:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <relativePath /> <!-- lookup parent from repository -->
    </parent>

    <properties>

        </dependency>
    </dependencies>

    <build>

            </plugin>
        </plugins>
        <finalName>MyProject</finalName>
    </build>

</project>

The main java application code snippet is as below -

@SpringBootApplication
public class MyApplication {

    public static void main(String[] args) throws IOException, InterruptedException {
        SpringApplication.run(MyApplication.class, args);
...

Now when i try to run the command mvn package i get below error -

I have tried excluding repackage as mentioned in many other posts, but no good. Any suggestions?

OS - Win 7 64 Bit

Maven - Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T22:11:47+05:30)

Also I picked a bare bone project from the spring intializr and tried mvn package and same error. Any issues related to my machine, maven or anything else?

Thanks

Try removing the `spring-loader` directory from the `.m2` directory in your home directory. Looks like it it broken/corrupted from an earlier download. You could also remove the whole `.m2` directory but that would force to download everything you ever downloaded. — M. Deinum, Oct 03 '16 at 06:19

Judging from the exception you got, the download for the spring-loaded dependency got corrupted.

Find the directory in which maven downloads the dependencies (by default the .m2 directory in your user dir). Find the spring-loaded directory and remove it. This will force maven to download the dependency again.

Instead of manually removing the dependencies you could also use the Maven dependency plugin to purge entires.

mvn dependency:purge-local-repository

This should remove the dependencies from the .m2 directory and force a re-download on the next mvn package. (See Force re-download of release dependency using Maven)

Looks like wrong version of spring-boot-loader-tools.jar is loaded. This link might help you to fix the issue

the spring boo loader tools jar file is corrupted

remove this folder from your local repository and run maven install to download the jar file again

\.m2\repository\org\springframework\boot\spring-boot-loader-tools
