NoClassDefFoundError for Gradle fat jar with tests Spring Boot

I need to create fat jar in Gradle project with tests where Main method is under src/test. Now I have Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/CommandLineParser when I run fat jar created by 'gradle bootJar'.

My Gradle:

plugins {
    id 'org.springframework.boot' version '2.1.7.RELEASE'
}

apply plugin: 'io.spring.dependency-management'

dependencies {
    compile group: 'org.springframework', name: 'spring-context', version: '5.1.9.RELEASE'
    compile group: 'org.springframework', name: 'spring-web', version: '5.1.9.RELEASE'
    compile group: 'org.springframework', name: 'spring-aop', version: '5.1.9.RELEASE'
    compile group: 'org.springframework', name: 'spring-aspects', version: '5.1.9.RELEASE'
    compile group: 'org.springframework', name: 'spring-test', version: '5.0.5.RELEASE'

    compile group: 'commons-cli', name: 'commons-cli', version: '1.4'
}

bootJar {
    manifest {
        attributes 'Start-Class': 'com.company.MainRunner'
    }
    from sourceSets.test.output.classesDirs
}

My spring.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true" xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>

Exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/CommandLineParser

Previously following 'gradle shadowJar' code worked well until I added AspectJ to the project

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.github.jengelman.gradle.plugins:shadow:4.0.3'
    }
}

apply plugin: 'com.github.johnrengelman.shadow'

shadowJar {
    manifest {
        attributes 'Main-Class': 'com.company.MainRunner'
    }
    from sourceSets.test.output.classesDirs

    configurations = [project.configurations.testRuntime]
}

And error appeared on running 'gradle shadowJar'

Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/aop]

Somewhere I found that shadowJar doesn't work properly with Spring

How can I create fat jar for Spring project with main class under src/test?

This Gradle shadowJar works for me

import com.github.jengelman.gradle.plugins.shadow.transformers.AppendingTransformer

shadowJar {
    mergeServiceFiles()
    transform(AppendingTransformer) { resource = 'META-INF/spring.handlers' }
    transform(AppendingTransformer) { resource = 'META-INF/spring.schemas' }

    manifest {
        attributes 'Main-Class': 'com.company.MainRunner'
    }
    from sourceSets.test.output.classesDirs

    configurations = [project.configurations.testRuntime]
}
