Static Content(from resources) not found in Fat JAR

[MichaelFay]

I am trying to compile and deploy a jat jar file that contains my business logic and static content. It runs perfectly fine in intellij however, when I build a jar for deployment through graddle I get resource not found. I have already modified my statics to use resources instead of files. Any help would be greatly appreciated.

sourceSets {
    main.kotlin.srcDirs = main.java.srcDirs = ['src']
    test.kotlin.srcDirs = test.java.srcDirs = ['test']
    main.resources.srcDirs = ['resources']
    test.resources.srcDirs = ['testresources']
}

    mavenLocal()
    jcenter()
    maven { url 'https://kotlin.bintray.com/ktor' }

@MichaelFay I cannot reproduce your problem with Ktor 1.5.1. Here is the sample project I've created from your description fatjar_static.zip. I did the following steps:

1. Generate fat JAR: ./gradlew fatjar
2. Run the application: java -jar build/libs/fatjar_static-all.jar -port=9000
3. Open http://localhost:9000/ in a browser

Hey! I've just come across this and I am having the same issue, did anyone ever find a solution?
