Hi

I’m playing around with gradle 3.3 and have some issues publishing a war file to a directory.

Using ‘gradlew uploadArchives’ results in a NullPointerException.

> - What went wrong:  
> Execution failed for task ‘:uploadArchives’.
> 
> > Could not publish configuration ‘archives’  
> > java.lang.NullPointerException (no error message)

I’m still trying to figure out why this NullPointerException occurs.

Tried some different approach by adding an own copy task.

> task deployLocal(type: Copy) {  
> configurations.archives.each( println(it) )

> ```
> from configurations.archives.allArtifacts*.file 
> into("file://c/temp/test/") 
> 
> ```
> 
> }

Unfortunately same error occurs. Anyone an idea?

> gradlew jar deployLocal

thx & regards
