From f6b200be4c8b90c26886c6cdd5809abac8c4ac15 Mon Sep 17 00:00:00 2001 From: James Moger Date: Wed, 27 Mar 2013 12:46:05 -0400 Subject: Reorganized to Apache Standard Directory Layout & integrated Moxie This is a massive commit which reorganizes the entire project structure (although it is still monolithic), removes the Build classes, and switches to Moxie, a smarter Ant build tookit based on the original Gitblit Build classes. The Ant build script will likely require additional fine-tuning, but this is big step forward. --- .../com/gitblit/client/GitblitManagerLauncher.java | 164 +++++++++++++++++++++ 1 file changed, 164 insertions(+) create mode 100644 src/main/java/com/gitblit/client/GitblitManagerLauncher.java (limited to 'src/main/java/com/gitblit/client/GitblitManagerLauncher.java') diff --git a/src/main/java/com/gitblit/client/GitblitManagerLauncher.java b/src/main/java/com/gitblit/client/GitblitManagerLauncher.java new file mode 100644 index 00000000..d0cc8393 --- /dev/null +++ b/src/main/java/com/gitblit/client/GitblitManagerLauncher.java @@ -0,0 +1,164 @@ +/* + * Copyright 2011 gitblit.com. + * + * Licensed under the Apache License, Version 2.0 (the "License");
