How to import external libraries in jshell java 9?

I tried with 9 Build 162 Linux 64-bit with preparation:

  • Downloaded guava-19.0.jar and commons-lang3-3.4.jar to /opt/libs

The following options are available:

  1. Specify CLASSPATH environment variable:

    $> CLASSPATH="/opt/libs/commons-lang3-3.4.jar:/opt/libs/guava-19.0.jar" bin/jshell

  2. Specify classpath with jshell option:

    $> bin/jshell --class-path /opt/libs/guava-19.0.jar:/opt/libs/commons-lang3-3.4.jar

  3. Configure evaluation context within jshell session with command /env, /reset or /reload(these commands are different, you can check out with its help info), take /env as example:

    jshell> /env -class-path /opt/libs/commons-lang3-3.4.jar:/opt/libs/guava-19.0.jar

And then you're able to either import org.apache.commons.lang3.StringUtils or import;.

  • You can load maven artifacts into JShell through this (modified) version of JShell.
  • It also supports /cls command to clear JShell Console. See Maven Example below.
