Throwing IllegalStateException when used along with ShadowJar plugin for packaging

[harshvs20]

I have a vertx application in which I am using ShadowJar for packaging as Jar. I tried using the swagger-gradle plugin but it always throws IllegalStateException
.
I then removed ShadowJar and it all works fine. Is there a compatibility issue here ?
I have a feeling that "Parboiled" is creating issue here.
Following are the version i am using:
Java - 1.8
Vertx - 3.0
shadowjar - id "com.github.johnrengelman.shadow" version "1.2.3"
swagger-gradle plugin - classpath 'io.github.swagger2markup:swagger2markup-gradle-plugin:1.0.0'

PLEASE HELP !!!
Here is the stacktrace:

@RobWin : Please help !!

[RobWin]

Unfortunately I can't help much. It's a problem of Gradle that Plugins classpaths are not isolated. This seems to be a problem with two different versions of the ASM library which is used by markdown-to-asciidoc (Parboiled)

[RobWin]

I already opened an issue against markdown-to-asciidoc.

Btw if you use Swagger2Markup, we would love to get your github star.

[JohnRudolfLewis]

I found a workaround to this problem. Don't use this plugin. Instead, add the cli jar to the classpath and use a JavaExec task instead.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
    }
    dependencies {
        classpath 'org.asciidoctor:asciidoctor-gradle-plugin:1.5.3'
        classpath 'org.asciidoctor:asciidoctorj-pdf:1.5.0-alpha.10.1'
        classpath 'io.github.swagger2markup:swagger2markup-cli:1.1.0'
        classpath "org.ajoberstar:gradle-git:1.5.1"
    }
}

...

task runSwagger2Markup(type: JavaExec) {
    main = "io.github.swagger2markup.cli.Application"
    workingDir = "$projectDir"
    classpath = project.buildscript.configurations.classpath
    args('convert', '-i', "$projectDir/src/main/resources/swagger.yaml", '-d', asciiDocOutputDir, '-c', "$projectDir/swagger2markup.properties")
}

Thx @JohnRudolfLewis
Good advice!
