Bug 504774 – dev-java/jflex-1.5.0 file collision

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Martin von Gagern 2014-03-16 10:15:34 UTC]

I thought I had this here reported already, but it seems I did not.

A world upgrade fails on jflex due to a file collision:

 * package dev-java/jflex-1.5.0 NOT merged
 * 
 * Detected file collision(s):
 * 
 * dev-java/jflex-1.4.3:0::gentoo
 *      /usr/bin/jflex

This is because I have jflex:0 installed. Simply adding a SLOT=1.5 to the ebuild doesn't allow the two versions to be installed simultaneously.

This is on top of the USE=doc issue reported in bug #498874 comment #2 which I avoided by setting USE=-doc.

[Comment 1 Kent Fredric (IRC: kent\n) (RETIRED) 2014-04-04 19:08:44 UTC]

A collision occurs with 

> /usr/share/vim/vimfiles/syntax/jflex.vim

Also happens with SLOT=1.5 vs SLOT=0

Not sure how you'll solve that, maybe split that into a separate app-vim/ package.

Same in jflex-1.5.1. Please fix this SLOT mess! Masking >=1.5 locally for now.

[Comment 3 Martin von Gagern 2015-01-25 14:10:33 UTC]

Same for jflex 1.6.0, which introduces yet another slot to provide the same launcher. Please fix this!

Here's my diff to fix the problem (discussed with fordfrog):

Going forward, package collisions should not occur again.
