git 创建新的本地分支然后推送远程分支（新远程）然后使用 JGIT 设置上游

Question

我要动态创建本地分支（比如 Hotfix_Test1、Hotfix_Test2 各在不同时间）并将其推送到远程。

这些分支应包含名为 Release 的分支中可用的源，该分支是另一个本地
版本已经使用 git 命令从本地推送到远程
git checkout -b 发布git push
git push --set-upstream origin Release

我创建了一个 git 对象并尝试使用以下代码动态创建修补程序分支

public static void main(String[] args) {
CreateBranchCommand createBranchCommand = null;
CheckoutCommand checkoutCommand = null;
Git git = null;
String releaseVersion = "Test";
PushCommand pushCommand = null;
StoredConfig config = null;
try {
/* Consider Git object is created */
git = createGitObject();

/* Checkout Release branch */
checkoutCommand = git.checkout();
checkoutCommand.setName("Release");
checkoutCommand.call();

/* Creating Hotfix Branch */
createBranchCommand = git.branchCreate();
createBranchCommand.setName("hotfix_" + releaseVersion).call();

/* Pushing Hotfix Branch to remote
 * note that the hotfix is not present in remote 
 */
pushCommand = git.push();
pushCommand.setRemote("origin");
pushCommand.setRefSpecs(new RefSpec("hotfix_" + releaseVersion + ":hotfix_" + releaseVersion));
pushCommand.call();

/* Trying to set upstream for newly created hotfix branch */
createBranchCommand.setUpstreamMode(SetupUpstreamMode.SET_UPSTREAM);
createBranchCommand.setStartPoint("origin/" + "hotfix_" + releaseVersion);
createBranchCommand.setForce(true);
createBranchCommand.call();
checkoutCommand.setName("hotfix_" + releaseVersion);
checkoutCommand.call();

/* Editing the configuration file in local */
config = git.getRepository().getConfig();
config.setString(ConfigConstants.CONFIG_BRANCH_SECTION, "hotfix_" + releaseVersion, "remote", "origin");
config.setString(ConfigConstants.CONFIG_BRANCH_SECTION, "hotfix_" + releaseVersion, "merge",
    "refs/heads/hotfix_" + releaseVersion);
config.save();
} catch (Exception exception) {
exception.printStackTrace();
}

}

当执行到这一行时

'createBranchCommand.setUpstreamMode(SetupUpstreamMode.SET_UPSTREAM);'

它抛出异常

java.lang.IllegalStateException：命令 org.eclipse.jgit.api.CreateBranchCommand 在错误的状态下调用

我不知道错在哪里。请帮忙解决错误。

您已经调用了 createdBranchCommand：

/* Creating Hotfix Branch */
createBranchCommand = git.branchCreate();
createBranchCommand.setName("hotfix_" + releaseVersion).call();

然后在再次尝试重新使用该 branchCreate() 命令之前进行了推送：

/* Trying to set upstream for newly created hotfix branch */
createBranchCommand.setUpstreamMode(SetupUpstreamMode.SET_UPSTREAM);
createBranchCommand.setStartPoint("origin/" + "hotfix_" + releaseVersion);
createBranchCommand.setForce(true);
createBranchCommand.call();

尝试一次创建分支并设置其上游配置，然后推送到它：

/* Creating Hotfix Branch */
createBranchCommand = git.branchCreate();
createBranchCommand.setName("hotfix_" + releaseVersion);
createBranchCommand.setUpstreamMode(SetupUpstreamMode.SET_UPSTREAM);
createBranchCommand.setStartPoint("origin/" + "hotfix_" + releaseVersion);
createBranchCommand.setForce(true);
createBranchCommand.call();

git 创建新的本地分支然后推送远程分支（新远程）然后使用 JGIT 设置上游

git new local branch creation then push remote branch(new remote) and then set upstream using JGIT

java

git

jgit
