Spring Boot fat jar renaming

When I try to rename the jar file generated on build Spring does not generate a fat jar anymore:

jar {
    manifest {
        attributes 'Main-Class': mainClassName
    }
    baseName = 'app'
    classifier = null
    version = null
}

I will see the app.jar in my /build/libs/ folder but it only contains the project not the dependencies and no other files are generated. How can I make Spring rename the jar it generates which includes the dependencies?

You have set the classifier on the jar task to null rather than the default of an empty string (""). Unless you explicitly configure bootRepackage to apply to a jar task, tasks with a non-default classifier are ignored. This is hinted at in the info-level logging of bootRepackage:

Jar task not repackaged (didn't match withJarTask): task ':jar'

The simplest thing to do is to leave the classifier with its default empty string value. This would leave your jar task with the following configuration:

jar {
    baseName = 'app'
    version = null
}

When bootRepackage runs, the app.jar file produced by the jar task will then be repackaged and contain its dependencies as you require.
