Hudson结账问题的Git插件

当使用Hudson的Git插件时,我的作业总是在从我的在线git存储库中获取最新的源代码时失败(git://github.com/ithena/orm2dsl.git).

git插件首先git fetch成功执行.然后它尝试执行git checkout -f origin/,失败,如下所示.这是我的git存储库的问题还是没有意义的checkout命令？

Git命令没有在作业配置中设置的分支:

git checkout -f origin/
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'origin/' which can not be resolved as commit?

在作业配置中将分支设置为master的Git命令:

git checkout -f origin/master
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'origin/master' which can not be resolved as commit?

Hudson控制台输出:

started
Checkout
[workspace] $ git fetch
Checking out origin/
[workspace] $ git checkout -f origin/
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'origin/' which can not be resolved as commit?
FATAL: Error checking out origin/
