Question

我正在尝试更新子模块：

git.submoduleUpdate().call()

但我明白了：

org.eclipse.jgit.api.errors.JGitInternalException: Missing unknown e88da827bdc5c5a4b0d87b8be79b81567759411b

有趣的是在控制台上它可以工作：

kontinuum@ligi-tp ~/k/w/l/SurvivalManual> git submodule update
remote: Counting objects: 27, done.
remote: Compressing objects: 100% (27/27), done.
remote: Total 27 (delta 17), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (27/27), done.

正如@ max630指出这是一个jgit错误：

https://bugs.eclipse.org/bugs/show_bug.cgi?id=470318

这是我现在的解决方法：

val walk = SubmoduleWalk.forIndex(git.repository)
while (walk.next()) {
   val submodule = walk.repository
   Git.wrap(submodule).fetch().call()
   submodule.close()
}

Answer 2

与git不同，JGit不会在子模块更新时获取新对象。要避免这种情况，您可以尝试启用递归获取：

git config fetch.recurseSubmodules true

我不知道jgit是否实现了它

使用JGit更新子模块时出现MissingObjectException
