uploadX task fails if both shadow 2.0.x and application plugin are applied. #347
Description
Shadow Version
1.2.4 vs. 2.0.0/2.0.1
Gradle Version
4.3.1/4.4-rc1
Expected Behavior
This example project (build.gradle is also provided below) should work with 2.0.x since it worked with 1.2.4.
Execute gradlew to run the default tasks.
Actual Behavior
Execution failed for task ':uploadPublished'.
> Could not publish configuration 'published'
> A POM cannot have multiple artifacts with the same type and classifier. Already have MavenArtifact gradle-shadow2:zip:zip:null, trying to add MavenArtifact gradle-shadow2:zip:zip:null.
If you remove the following two lines, the build will work.
apply plugin: 'application'
mainClassName = 'foo.Main'If you instead switch back from 2.0.1 to 1.2.4, the build will work.
If you use Gradle 4.4-rc1, neither will work. See gradle/gradle#3589
