perhaps it's not a bug...but maybe it is.

here's a clearer demonstration:

thufir@dur:~/NetBeansProjects/gradleHelloWorld$ 
thufir@dur:~/NetBeansProjects/gradleHelloWorld$ sdk use gradle 4.3.1

Using gradle version 4.3.1 in this shell.
thufir@dur:~/NetBeansProjects/gradleHelloWorld$ 
thufir@dur:~/NetBeansProjects/gradleHelloWorld$ gradle clean runShadow

> Task :shadowJar 
A problem was found with the configuration of task ':shadowJar'. Registering invalid inputs and outputs via TaskInputs and TaskOutputs methods has been deprecated and is scheduled to be removed in Gradle 5.0.
 - No value has been specified for property 'mainClassName'.
The SimpleWorkResult type has been deprecated and is scheduled to be removed in Gradle 5.0. Please use WorkResults.didWork() instead.

> Task :startShadowScripts 
Using TaskInputs.file() with something that doesn't resolve to a File object has been deprecated and is scheduled to be removed in Gradle 5.0. Use TaskInputs.files() instead.


FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':installShadowDist'.
> The specified installation directory '/home/thufir/NetBeansProjects/gradleHelloWorld/build/install/gradleHelloWorld-shadow' is neither empty nor does it contain an installation for 'gradleHelloWorld'.
  If you really want to install to this directory, delete it and run the install task again.
  Alternatively, choose a different installation directory.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
