This is because you might be having one of the jars in your maven cache corrupted, which is actually pointed out by IllegalStateException
.
Try removing the corrupted jar from your maven cache and re-build your application.
In your case just delete this particular file and rebuild your application.
file:/C:/Users/HP%20PC/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/**spring-plugin-core-1.2.0.RELEASE.jar
