Plugin dependencies conflicts

Bugs

Hello guys.
I have faced a strange behavior of plugin-dependencies management.
I have the project with the following structure:
|root_project|
…build.gradle
…|sub_project|
…build.gradle

In |root_project|/build.gradle I have a plugin dependency on Bintray uploader plugin:

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.6'
  }
}

apply plugin: ‘com.jfrog.bintray’

In |sub_project|/build.gradle I have a plugin dependency on Shadow-plugin:

buildscript {
  repositories { jcenter() }
  dependencies {
    classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.3'
  }
}

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

And when I attempt to execute “shadowJar” task I get the following [exception] (Exception Gradle - Pastebin.com).
It seems to me that it caused by the two different underlying versions of the same library (Apache Ant Core) in plugin “bintray” and plugin “shadow”.
If I disable a “bintray” plugin the "shadow"ing passes successfully. I guess that you load all the libraries with the same class-loader so the problem class (org.apache.tools.zip.ZipOutputStream) is loaded firstly.
How to avoid this?

There is currently no isolation between the dependencies of different plugins. You’ll either have to look for newer versions of either plugin or see if there is an apache-zip version that both can work with.
