Gradle 2.2: No signature of method: ShadowJar_Decorated.getManifest()

[drazzib]

Hi !

I'm pursuing my journey to support Gradle 2.2 into Shadow plugin.
Since latest Gradle 2.2-RC2 fixed issue #95, I've been able to run my project build a step further.

Right now, I'm having issue with ShadowJar#getManifest method in ShadowJar :

Caused by: groovy.lang.MissingMethodException: No signature of method: com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar_Decorated.getManifest() is applicable for argument types: () values: []
Possible solutions: getManifest(), getManifest(), getManifest(), setManifest(org.gradle.api.java.archives.Manifest), setManifest(org.gradle.api.java.archives.Manifest), manifest(groovy.lang.Closure)

Given that comment for this method is

    // This should really return InheritManifest but cannot due to https://jira.codehaus.org/browse/GROOVY-5418
    // TODO - change return type after upgrade to Gradle 2

I'm assuming there might be something wrong here.

Regards !

As a side note, I've tried to remove this override (ie. remove getManifest method from ShadowJar source code) and it seems to work for my use case.

This worked in gradle-2.1. I just ran into the same problem when switching to gradle 2.2. Seems like the gradle people broke something for shadowJar.

Sorry, should have checked open issues before opening a new one ;).

I'm working on adding support for Gradle 2.2, but I've run into another incompatibility that I haven't figure a workaround yet for. I've reached out to the Gradle team to see if they have any ideas.
