JShell Standalone

Provides a standalone version of the JShell REPL. Anything needed to run JShell independently is contained, so there is no need to install the full JDK. A minimal Java runtime is embedded and compressed using the jlink tool.

This minimal version consists only of the modules necessary to run JShell: “java.base”, “jdk.zipfs” and “jdk.jshell”.
However the user can manually provide any JDK or custom module on startup with --add-module.

Note that the startup time of JShell 10 was significantly improved.

Caveat: The default JShell editor is not available. An editor can be set in JShell e.g. with /set editor C:/Program Files (x86)/Notepad++/notepad++.exe

Download

Note that the mostly “General Availability” JDK (x64) releases are used and not always the newest patch releases.

Build

Windows

  • Checkout this repository. That directory will be referenced as \
  • Install Java JDK 9 or higher

  • Set environment variable %JAVA_HOME% to the Java installation directory. Replace with the installed version:

    set JAVA_HOME = C:\PROGRA~1\java\jdk-<version>

  • Add %JAVA_HOME% to the %PATH%, if it is not already:

    set PATH = "%PATH%;%JAVA_HOME%\bin"

  • Open the command line
  • Check if Java is accessible with java -version
  • Change directory to \

  • Compile the project to \/mods/com.standalone.jshell:

    javac -d ./mods/com.standalone.jshell ./src/com.standalone.jshell/module-info.java ./src/com.standalone.jshell/com/standalone/jshell/JShellStandalone.java

    If successful, the compiled files can be found in \/mods.
    JShellStandalone.java is only used to have something to compile.
    More importantly the module-info.java contains dependencies on “jdk.zipfs” and jdk.jshell”.

  • Bundle the Java runtime (semicolon as path separator):

    jlink --module-path "%JAVA_HOME%/jmods;./mods" --add-modules com.standalone.jshell --output ./target --compress zip-9 --strip-debug --no-header-files --no-man-pages

    If successful, the binaries can be found in \/target/bin.

  • Run \/target/bin/jshell.exe

Linux

  • Checkout this repository. That directory will be referenced as \
  • binutils need to be installed for objcopy
  • Install Java 9 or higher. E.g. How to manually install Java on Ubuntu.
  • Set the installed Java to default, check with java -version
  • In the terminal, change directory to \

  • Compile the project to \/mods/com.standalone.jshell:

    javac -d ./mods/com.standalone.jshell ./src/com.standalone.jshell/module-info.java ./src/com.standalone.jshell/com/standalone/jshell/JShellStandalone.java

    If successful, the compiled files can be found in \/mods.
    JShellStandalone.java is only used to have something to compile.
    More importantly the module-info.java contains dependencies on “jdk.zipfs” and jdk.jshell”.

  • Bundle the Java runtime (colon as path separator):

    jlink --module-path $JAVA_HOME/jmods:./mods --add-modules com.standalone.jshell --output ./target --compress zip-9 --strip-java-debug-attributes --no-header-files --no-man-pages

    If successful, the binaries can be found in \/target/bin.

  • Run jshell in \/target/bin/
