Gradle build failure should show informative message

[abhinayagarwal]

Gradle build fails when one or more packages are not present on linux environment. Instead of throwing some useful information, the following message is shown:

FAILURE: Build failed with an exception.

* Where:
Script '~/Documents/openjdk-jfx/buildSrc/linux.gradle' line: 88

* What went wrong:
A problem occurred evaluating script.
> Cannot invoke method split() on null object

With this fix, when the build fails because of missing packages, a more informative message is shown.

FAILURE: Build failed with an exception.

* Where:
Script '~/Documents/openjdk-jfx/buildSrc/linux.gradle' line: 94

* What went wrong:
A problem occurred evaluating script.
> GTK2 development packages not found. If GTK2 packages are installed, please remove the build directory and try again.

+1 from me.
I had this error before as well, and a cryptic message about a NULL object doesn't inform the developer of the cause.

Looks good to me, too. Have you signed the OCA yet? I don't see your name on the list of OCA Signatories

Hi Kevin,

I had signed and mailed the OCA on March 27th.

OK, thanks.
