From 2d202087a58af962aa6866a1ef23e977d140a5ed Mon Sep 17 00:00:00 2001 From: Rishabh Budhouliya Date: Sat, 4 Apr 2020 01:30:56 +0530 Subject: [PATCH 1/3] Add clone option which enables core.longpaths Windows for git can't work with a directory having a name with greater than 255 characters. This clone option will add core.longpaths as true in git config globally, which will enable mysys git to work with directories having >255 char names. The addition is supported by both command line git and jgit. --- .../jenkinsci/plugins/gitclient/CliGitAPIImpl.java | 11 +++++++++++ .../jenkinsci/plugins/gitclient/CloneCommand.java | 7 +++++++ .../jenkinsci/plugins/gitclient/JGitAPIImpl.java | 13 +++++++++++++ 3 files changed, 31 insertions(+) diff --git a/src/main/java/org/jenkinsci/plugins/gitclient/CliGitAPIImpl.java b/src/main/java/org/jenkinsci/plugins/gitclient/CliGitAPIImpl.java index f020dca946..15718319ed 100644 --- a/src/main/java/org/jenkinsci/plugins/gitclient/CliGitAPIImpl.java +++ b/src/main/java/org/jenkinsci/plugins/gitclient/CliGitAPIImpl.java @@ -648,6 +648,7 @@ public CloneCommand clone_() { private String origin = "origin";
