如何仅使用Git将Git分支中的更改合并到SVN的“主干”中

Question

我想签出一个SVN项目，在远程SVN上创建一个分支，以及相应的本地Git分支。然后我想做一些改变。更改应该反映在两个分支中- SVN和Git，因为有些人在SVN中工作，他们应该看到分支task3。

下面的脚本成功地做到了这一点：

#!/bin/bash
DIR=/tmp/svn-experiments # Directory for experiments
rm -rf "$DIR"
mkdir "$DIR"

cd $DIR
rm -rf svnrepos
svnadmin create svnrepos

# Create a project with standard SVN-project folder structure:
mkdir -p project/{trunk,branches,tags}
cd project/trunk/
echo "Hello" > readme.txt
echo "Log entry 1" > day.log

# Import the project into repository
svn import -m "Project import into repository" "$DIR"/project file://"$DIR"/svnrepos/project

svn log file://"$DIR"/svnrepos/project

# Simulate two users and conflict

# Developer 1 (svn) creates working copy, branch:
svn co file://"$DIR"/svnrepos/project "$DIR"/developer_svn1

cd "$DIR"/developer_svn1

svn copy file://"$DIR"/svnrepos/project/trunk file://"$DIR"/svnrepos/project/branches/task1 -m "Create a branch for task 1" 

svn update

cd "$DIR"/developer_svn1/branches/task1

sed -i -r 's/(.*)/\1 world/g' readme.txt

svn commit -m "Change from developer_svn1"

svn update

# Developer 2 (svn) creates working copy, branch:
svn co file://"$DIR"/svnrepos/project "$DIR"/developer_svn2

cd "$DIR"/developer_svn2

svn copy file://"$DIR"/svnrepos/project/trunk file://"$DIR"/svnrepos/project/branches/task2 -m "Create a branch for task 2" 

svn update

cd "$DIR"/developer_svn2/branches/task2

sed -i -r 's/(.*)/\1 Russia/g' readme.txt

svn commit -m "Change from developer_svn2"

svn update

# Currently creates a remote SVN branch 'task3' and the corresponding local Git branch 'task3'
# Commits to local and remote
# TODO How to merge changes in 'task3' into 'trunk' of SVN by using Git only?
git-workflow() {
# Developer 3 (git) creates working copy, branch:
git svn clone -s file://"$DIR"/svnrepos/project "$DIR"/developer_git1

cd "$DIR"/developer_git1

git svn -m "Create a branch for task 3" branch task3 # The branch will be created on SVN

git branch task3 remotes/origin/task3 

git checkout task3

sed -i -r 's/(.*)/\1 Germany/g' readme.txt

git add -u

git commit -m "Change from developer_git1" # Commit in local Git branch

git svn dcommit # Commit to the corresponding SVN branch

}

但是我不知道如何将本地Git分支task3中的更改合并到SVN的trunk中。

我尝试了以下几种方法：

/tmp/svn-experiments/developer_git1$ git branch -a
  master
* task3
  remotes/origin/task1
  remotes/origin/task2
  remotes/origin/task3
  remotes/origin/trunk
/tmp/svn-experiments/developer_git1$ git checkout master
Switched to branch 'master'

如何强制master指向trunk并在那里提交？

我从来没有见过有人使用git推送到SVN的情况。如果您正在使用SVN工作流，则应该使用tortoiseSVN而不是git。参见https://tortoisesvn.net/。
