Re: [Geotools-devel] [jira] Created: (GEOT-3268) Intermittent build failure in gt-feature-pregeneralized ShapeFilePreGeneralizedFeatureSourceTest

[Michael B. <mic...@gm...>]

Hi Ben and all,

I also struck this same error when I updated and built trunk for the
first time in several months a couple of days ago.

My first thought was: "Oh no, I've forgotten how to do this !".  Then
I re-ran the build and it succeeded. Since then I've done another
couple of builds without striking the error.

Michael
