importOrderFile fails on "all unmatched type imports" group

[benjaminhawkeslewis]

If you create an Eclipse import order including an "all unmatched type imports" group and attempt to use it with Spotless, Spotless errors.

Example import order file matching the Google Java style guide:

#Organize Import Order
#Sat Aug 22 12:43:31 BST 2015
4=javax
3=java
2=
1=com.google
0=\#

Note that "all unmatched type imports" (as the Eclipse UI phrases it) is represented by an empty string (number 2).

I think the error is produced in

spotless/src/main/java/com/diffplug/gradle/spotless/java/ImportSorterStep.java

Line 54 in 191e7dd

String name = pieces[1];

where it is assumed that splitting the line on = will produce two strings.

Good find! There's a test harness for the import ordering here, which should make it easy to test a fix.

I should be able to look into a fix by Wednesday. If you'd like to do it yourself before then, I'd be happy to help in the gitter chat and merge the PR.

Implemented in 1.2.0.
