Created attachment 383938 [details] Ebuild for antlr v4.4 This ebuild forks well for me, hope it will help.
dev-java/antlr-4.5 was released on 2015-01-23.
+*antlr-4.4 (26 Mar 2015) + + 26 Mar 2015; Patrice Clement <monsieurp@gentoo.org> +antlr-4.4.ebuild: + Version bump courtesy of silver_ghost@list.ru. Fix bug 462778. +
As far as v4.5 is concerned, well... My day was, so far, fine. Until I decided to look into bumping this package to v4.5. So I opened the attachment linked to this bug and slapped it into an ebuild file. I then tried to see what would be the result, if miraculously, it would compile and install fine. Oh man how wrong I was. Since antlr-4.5 was released on 2015-01-23, as pointed out by Arfrever, I named the ebuild "antlr-4.5.ebuild". So far so good. patrice@vmint ~/gentoo-x86/dev-java/antlr $ ls antlr-2.7.7-r2.ebuild antlr-2.7.7-r5.ebuild antlr-3.1.3-r3.ebuild antlr-4.5.ebuild ChangeLog CVS files Manifest metadata.xml patrice@vmint ~/gentoo-x86/dev-java/antlr $ ebuild antlr-4.5.ebuild clean manifest configure test install Appending /home/patrice/gentoo-x86 to PORTDIR_OVERLAY...

He did reinvent the wheel. What went wrong? No idea. If someone is interested in bumping this package to v4.5, be my guest, open a bug and assign it to yourself. I'm not willing to waste my time deciphering a one-off script written by a maintainer who's clearly not aware of common Java packaging tools (ant, maven, gradle et al.).
