From 2ae1ed6336b1b1194cdee24975354eec9635e5f8 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Fri, 5 Oct 2018 00:21:08 -0400 Subject: [PATCH] Hook into CB's plugin rewriting system Primarily to update plugins for our fastutil relocation. Can also be used to do things like debug plugins accessing versioned NMS packages in an IDE pre-relocate step. --- .../0385-Hook-into-CB-plugin-rewrites.patch | 191 ++++++++++++++++++ 1 file changed, 191 insertions(+) create mode 100644 Spigot-Server-Patches/0385-Hook-into-CB-plugin-rewrites.patch diff --git a/Spigot-Server-Patches/0385-Hook-into-CB-plugin-rewrites.patch b/Spigot-Server-Patches/0385-Hook-into-CB-plugin-rewrites.patch new file mode 100644 index 0000000000..5cd06305fa --- /dev/null +++ b/Spigot-Server-Patches/0385-Hook-into-CB-plugin-rewrites.patch @@ -0,0 +1,191 @@ +From 68c9d90c9a39b36f3dd7031bb0b0757822cfaec0 Mon Sep 17 00:00:00 2001 +From: Zach Brown +Date: Wed, 3 Oct 2018 20:09:18 -0400 +Subject: [PATCH] Hook into CB plugin rewrites + +Allows us to do fun stuff like rewrite the OBC util fastutil location to +our own relocation.
