Playing with Spring on Windows

Spring project This repository gathers Spring code examples coming from various websites and books.
It also includes several build scripts (Bash scripts, batch files, Gradle scripts) for experimenting with Spring on a Windows machine.

Ada, Akka, C++, Dart, Deno, Docker, Flix, Golang, GraalVM, Haskell, Kafka, Kotlin, LLVM, Modula-2, Node.js, Rust, Scala 3, Spark, TruffleSqueak and WiX Toolset are other topics we are continuously monitoring.

Project dependencies

This project depends on the following external software for the Microsoft Windows platform:

☛ Maven packages
We present the Maven package dependencies in document PACKAGES.md.

Optionally one may also install the following software:

☛ Installation policy
When possible we install software from a Zip archive rather than via a Windows installer. In our case we defined C:\opt\ as the installation directory for optional software tools (in reference to the /opt/ directory on Unix).

For instance our development environment looks as follows (March 2024) 1:

C:\opt\apache-maven\            ( 10 MB)
C:\opt\Git\                     (367 MB)
C:\opt\gradle\                  (135 MB)
C:\opt\jdk-temurin-11.0.22_7\   (300 MB)
C:\opt\jdk-temurin-17.0.10_7\   (301 MB)
C:\opt\jdk-temurin-21.0.2_13\   (326 MB)

🔎 Git for Windows provides a Bash emulation used to run git from the command line (as well as over 250 Unix commands like awk, diff, file, grep, more, mv, rmdir, sed and wc).

Batch/Bash commands

setenv.bat 2

We execute command setenv.bat once to setup our development environment; it makes external tools such as gradle.bat, git.exe and sh.exe directly available from the command prompt.

> setenv -verbose
Tool versions:
   javac 17.0.10, java 17.0.10,
   gradle 8.6, mvn 3.9.6,
   git 2.44.0.windows.1, diff 3.10, bash 5.2.26(1)-release
Tool paths:
   C:\opt\jdk-temurin-17.0.10_7\bin\javac.exe
   C:\opt\jdk-temurin-17.0.10_7\bin\java.exe
   C:\opt\gradle\bin\gradle.bat
   C:\opt\apache-maven\bin\mvn.cmd
   C:\opt\Git\bin\git.exe
   C:\opt\Git\usr\bin\diff.exe
   C:\opt\Git\bin\bash.exe
Environment variables:
   "GIT_HOME=C:\opt\Git"
   "GRADLE_HOME=C:\opt\gradle"

C:\opt\apache-maven\bin\mvn
C:\opt\apache-maven\bin\mvn.cmd
C:\opt\Git\bin\sh.exe
C:\opt\Git\usr\bin\sh.exe

🔎 Subcommand help prints the following help message :

  > setenv help
  Usage: setenv { <option> | <subcommand> }
   
    Options:
      -bash       start Git bash shell instead of Windows command prompt
      -debug      print commands executed by this script
      -verbose    print progress messages
   
    Subcommands:
      help        print this help message

[1] Downloads ↩

In our case we downloaded the following installation files (see section 1): 
apache-maven-3.9.6-bin.zip                         ( 10 MB)
gradle-8.6-bin.zip                                 (110 MB)
OpenJDK11U-jdk_x64_windows_hotspot_11.0.22_7.zip   ( 99 MB)
OpenJDK17U-jdk_x64_windows_hotspot_17.0.10_7.zip   (176 MB)
OpenJDK21U-jdk_x64_windows_hotspot_21.0.2_13.zip   (191 MB)
PortableGit-2.44.0-64-bit.7z.exe                   ( 55 MB)

[2] setenv.bat usage ↩

Batch file setenv.bat has specific environment variables set that enable us to use command-line developer tools more easily.
It is similar to the setup scripts described on the page "Visual Studio Developer Command Prompt and Developer PowerShell" of the Visual Studio online documentation.
For instance we can quickly check that the two scripts Launch-VsDevShell.ps1 and VsDevCmd.bat are indeed available in our Visual Studio 2019 installation : 
> where /r "C:\Program Files (x86)\Microsoft Visual Studio" *vsdev*
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\Launch-VsDevShell.ps1
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\VsDevCmd.bat
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\vsdevcmd\core\vsdevcmd_end.bat
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\vsdevcmd\core\vsdevcmd_start.bat
Concretely, in our GitHub projects which depend on Visual Studio (e.g. michelou/cpp-examples), setenv.bat does invoke VsDevCmd.bat (resp. vcvarall.bat for older Visual Studio versions) to setup the Visual Studio tools on the command prompt.
