+===== Setting up Rsync folder-synch on Windows =====
+=== Why ===
+When **developing code** in an **IDE on Windows-Host** \\
+I would like to have the possibility
+of running code in the Guest-VM. In an environment as close to the deployment as possible: \\
+e.g. on Kubernetes, integrated with other containers.
+**File-system watcher:**
+Requirement:
+On the Guest - the changes of "file-system" of code-project must be recognized\\
+and the code-project rebuilt. \\
+Also changes in the **IDE on Windows-Host** \\
+must trigger changes on the file-system in "Guest-VM". \\
+Problem:
+When sharing a code-project via **Oracle-Virtualbox shared-folders** \\
+and files where changed on **IDE on Windows-Host** \\
+unfortunately, **NO changes where triggered** on **Guest** file-system-watcher.
+When sharing a code-project via **Rsync**  - the requirement was fulfilled.
+=== How ===
+An example of setting up the environment
+  *   On Guest. Install Cygwin, to get Rsync on Windows
+  *   On Guest. Add the "code-project-folder" to the same folder, where "Vagrantfile" is located
+  *   Configure Vagrantfile to sync "code-project-folder"
+  *   On Guest. Run automatic sync command in one cmd-shell
+  *   Ssh into Vagrant. Run continuos build in one shell
+  *   Configure the Spring Boot application to hot-deploy changes
+  *   Ssh into Vagrant. Run application like Spring Boot application
+== On Guest. Install Cygwin, to get Rsync on Windows ==
+<code>
+winget install -e --id Cygwin.Cygwin
+</code>
+==On Guest. Add the "code-project-folder" to the same folder, where "Vagrantfile" is located==
+<code>
+cd "VagrantProjectFolder"
+mkdir "spring-boot-code-project-folder"
+</code>
+==Configure Vagrantfile to sync "code-project-folder"==
+Sync folder `spring-boot-code-project-folder`.
+Based on `checksum`, not timestamp.
+Vagrantfile
+<sxh ruby>
+...
+	config.vm.synced_folder "./spring-boot-code-project-folder", "//mnt/spring-boot-code-project-folder/",
+		type: "rsync",
+		rsync__auto: true,
+		rsync__args: ["--verbose", "--ignore-times", "--checksum", "--rsync-path='rsync'", "--archive", "--delete", "-z"],
+		id: "spring"
+..
+</sxh>
+==On Guest. Run automatic sync command in one cmd-shell==
+Open a new [[https://apps.microsoft.com/store/detail/windows-terminal/9N0DX20HK701?hl=de-ch&gl=ch| Windows-Terminal ]] Tab and run the continuous sync in there:
+<sxh shell>
+vagrant rsync-auto
+</sxh>

+==Ssh into Vagrant. Run continuos build in one shell==
+See https://docs.gradle.org/current/userguide/command_line_interface.html#sec:continuous_build
+Skip the tests.\\
+Dont use the daemon.
+<sxh shell>
+vagrant ssh
+cd "/mnt/spring-boot-code-project-folder"
+./gradlew build -xtest --no-daemon --continuous
+</sxh>
+== Configure the Spring Boot application to hot-deploy changes ==
+The Spring boot applications needs to be advised, \\
+to take up any rebuilt app and hot-deploy it.
+Add dependency to "devtools".
+build.gradle
+<sxh>
+dependencies {
+	// makes Spring boot hot swap rebuilt jar to tomcat
+	developmentOnly 'org.springframework.boot:spring-boot-devtools'
+}
+</sxh>
+==Ssh into Vagrant. Run application like Spring Boot application==
+<sxh shell>
+vagrant ssh
+cd "/mnt/spring-boot-code-project-folder"
+./gradlew bootRun --args='--server.port=8888'
+</sxh>

+===== Error: Authentication failure. Retrying... =====
+Thats also the reason for disk /mnt/d not being mounted correctly
+<sxh shell>
+	# give the home permissions back to vagrant
+	# without that -  /home/vagrant is owned by root.
+	# and also /home/vagrant/.ssh/authorized_keys
+	# so that no ssh connection works and
+	# vagrant ssh - failes with "Error: Authentication failure. Retrying..."
+	sudo chown -R vagrant:vagrant "/home/vagrant"
+</sxh>
