Subject: [PATCH] Ignore/exclude IDEA-generated classpath index files (#2094)

See
https://youtrack.jetbrains.com/issue/IDEA-305759/Gradle-cannot-handle-classpath.index-duplicates
for more info -- it looks like this is fixed in some recent versions but
as of right now it doesn't seem like it's fixed on the Google-managed
version
