本文介绍了使用jgit Git获取失败:远程没有< branchname>可用于获取的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我有一个位于 main.git 的裸回购,并试图获取一个分支( foo ,让我们在另一个回购中, test ,它只是 git init 'd: fetchtest / | - main.git / | - test / | - .git / 使用常规的git命令,我可以执行 git fetch ../main.git foo :foo ,这将在 test / 中创建一个新的分支 foo 并获取对象分支机构所需的。 然后我想做同样的事情,但以编程方式使用JGit,即不使用git CLI,而只使用Java代码。我无法使用git CLI: Git git = Git.init()。setDirectory(新文件(fetchtest / test /))。call(); git.fetch()。setRemote(new File(../ main.git)) .setRefSpecs(new RefSpec(foo:foo)) 。呼叫(); 但只是出现错误: org.eclipse.jgit.api.errors.TransportException:远程没有foo可用于提取。 在org.eclipse.jgit.api.FetchCommand.call(FetchCommand.java:137) // ...... 引起:org.eclipse.jgit.errors。 TransportException:远程没有foo可用于提取。 at org.eclipse.jgit.transport.FetchProcess.expandSingle(FetchProcess.java:349) at org.eclipse.jgit.transport.FetchProcess.executeImp(FetchProcess.java:139) at org.eclipse.jgit.transport.FetchProcess.execute(FetchProcess.java:113) at org.eclipse.jgit.transport.Transport.fetch(Transport.java:1069) at org.eclipse .jgit.api.FetchCommand.call(FetchCommand.java:128) 如何获取此内容工作? 解决方案应该如何工作: Git git = Git.init()。setDirectory(new File(fetchtest / test /))。call(); git.fetch()。setRemote(new File(../ main.git)) .setRefSpecs(new RefSpec(refs / heads / foo:refs / heads / foo)) .call(); 请注意 RefSpec 定义。 至少,试试你的例子: new RefSpec(refs / heads / foo:refs / heads / foo) RefSpec class 提及: / ** *解析运输操作中使用的参考规格。 *< p> *规格通常是以下形式之一: *< ul> *< li>< code> refs / head / master< / code>< / li> *< li>< code> refs / head / master:refs / remotes / origin / master< / code>< / li> *< li>< code> refs / head / *:refs / remotes / origin / *< / code>< / li> *< li>< code> + refs / head / master< / code>< / li> *< li>< code> + refs / head / master:refs / remotes / origin / master< / code>< / li> *< li>< code> + refs / head / *:refs / remotes / origin / *< / code>< / li> *< li>< code>:refs / head / master< / code>< / li> *< / ul> * * @param spec *描述规格的字符串。 * @throws IllegalArgumentException *规范无效。 * / 所以 refs / head / 似乎是强制性的。 原始答案: api.FetchCommand 上的nofollow> setRemote()函数需要一个名称或URI。 / p> 然后查看 FetchCommandTest URI定义,我更喜欢让远程更加可见: 我宁愿为你的第二个仓库(指你的第一个仓库)定义一个命名的远程仓库(这里下面是: test ),然后获取。 //设置第一个存储库以从第二个存储库中获取 final StoredConfig config = db.getConfig(); RemoteConfig remoteConfig =新的RemoteConfig(config,test); URIish uri = new URIish(db2.getDirectory()。toURI()。toURL()); remoteConfig.addURI(uri); remoteConfig.update(config); config.save(); //通过提交和标记创建一些refs RevCommit commit = git2.commit()。setMessage(initial commit)。call(); Ref tagRef = git2.tag()。setName(tag)。call(); Git git1 = new Git(db); RefSpec spec = new RefSpec(refs / heads / master:refs / heads / x); git1.fetch()。setRemote(test)。setRefSpecs(spec) .call(); I have a bare repo located at main.git and am trying to fetch a branch (foo, let's say) in another repo, test, which has only just been git init'd:fetchtest/ |- main.git/ |- test/ |- .git/Using regular git commands, I can do a git fetch ../main.git foo:foo and this will make a new branch foo in test/ and fetch the objects required for the branch. I then want to do the same thing but programmatically using JGit, ie not using the git CLI but using only Java code. There is no way I can use the git CLI:Git git = Git.init().setDirectory(new File("fetchtest/test/")).call();git.fetch().setRemote(new File("../main.git")) .setRefSpecs(new RefSpec("foo:foo")) .call();but it just errors with:org.eclipse.jgit.api.errors.TransportException: Remote does not have foo available for fetch. at org.eclipse.jgit.api.FetchCommand.call(FetchCommand.java:137) // ......Caused by: org.eclipse.jgit.errors.TransportException: Remote does not have foo available for fetch. at org.eclipse.jgit.transport.FetchProcess.expandSingle(FetchProcess.java:349) at org.eclipse.jgit.transport.FetchProcess.executeImp(FetchProcess.java:139) at org.eclipse.jgit.transport.FetchProcess.execute(FetchProcess.java:113) at org.eclipse.jgit.transport.Transport.fetch(Transport.java:1069) at org.eclipse.jgit.api.FetchCommand.call(FetchCommand.java:128)How do I get this to work? 解决方案 What should work:Git git = Git.init().setDirectory(new File("fetchtest/test/")).call();git.fetch().setRemote(new File("../main.git")) .setRefSpecs(new RefSpec("refs/heads/foo:refs/heads/foo")) .call();Note the RefSpec definition.At least, try in your example:new RefSpec("refs/heads/foo:refs/heads/foo")The RefSpec class mentions:/** * Parse a ref specification for use during transport operations. * <p> * Specifications are typically one of the following forms: * <ul> * <li><code>refs/head/master</code></li> * <li><code>refs/head/master:refs/remotes/origin/master</code></li> * <li><code>refs/head/*:refs/remotes/origin/*</code></li> * <li><code>+refs/head/master</code></li> * <li><code>+refs/head/master:refs/remotes/origin/master</code></li> * <li><code>+refs/head/*:refs/remotes/origin/*</code></li> * <li><code>:refs/head/master</code></li> * </ul> * * @param spec * string describing the specification. * @throws IllegalArgumentException * the specification is invalid.*/So "refs/head/" seems mandatory.Original answer:The setRemote() function on api.FetchCommand takes a name or an URI.And looking at the FetchCommandTest URI definition, I prefer making the remote more visible:I would rather define a named remote (here below: "test") for your second repo (referring your first repo), and then fetch.// setup the first repository to fetch from the second repositoryfinal StoredConfig config = db.getConfig();RemoteConfig remoteConfig = new RemoteConfig(config, "test");URIish uri = new URIish(db2.getDirectory().toURI().toURL());remoteConfig.addURI(uri);remoteConfig.update(config);config.save();// create some refs via commits and tagRevCommit commit = git2.commit().setMessage("initial commit").call();Ref tagRef = git2.tag().setName("tag").call();Git git1 = new Git(db);RefSpec spec = new RefSpec("refs/heads/master:refs/heads/x");git1.fetch().setRemote("test").setRefSpecs(spec).call(); 这篇关于使用jgit Git获取失败:远程没有< branchname>可用于获取的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 09-14 17:39
