mrsarm / jshell-plugin Goto Github PK

Added the plugin in the following version:

id "com.github.mrsarm.jshell.plugin" version "1.0.0-RC1"

Running the command:

./gradlew --no-daemon build -x test --console plain jshell

Leads to it successfully building and starting JShell but i doesn't grant me interactive input and stops as "BUILD SUCCESSFUL" immediately after:

To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/6.3/userguide/gradle_daemon.html.
Daemon will be stopped at the end of the build stopping after processing

jshell> int a = 100

when I type left arrow key， as follows

jshell> int a = 100^[[D

I've got everything in my project using Java17:

% echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home/
% which java
/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home/bin/java
% which jshell
/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home/bin/jshell

Similarly, my build.gradle specifies Java17 in all the right places and if I call System.getProperty("java.version"), it prints "17.0.1".

But, when I run ./gradlew --console plain jshell, I get this:

...
> Task :jshell
|  Welcome to JShell -- Version 11.0.7

jshell> 

Is this configurable somewhere?

When writing to stdout using for instance System.out.println, the line is printed as appended to the end of the line, instead of on a new line of its own:

println(1)1

I would expect a new line after println:

println(1)
1

hello

plugin is not working in Windows.

jshell is started, but there is no my classes around.

In windows, if classpath is sent as a one string, multiple dirs and jars are separated by the ; char, not by : char as in linux.

is this handled correctly in your plugin?

Hi,

When starting the gradle jshell plugin, seems to print a regular tab, instead of triggering code completion. If I launch jshell directly, tab works fine.

I'm under linux, and tried to play with TERM variable a bit, but didn't succeed.

There might be something I'm missing. Could you help me, or point me to a resource to help me.

Thanks in advance

Even when running

./gradlew --console plain classes jshell

I still get the message

:jshell task :classes not found, be sure to compile the project first

I haven't been able to figure out what could be causing this. Could you point me in the right direction?

I'm using Java 13.0.1 and Gradle 6.5 on macOS Catalina (10.15.4).

Is this a known problem or something related to my local setup?

Thanks!

See the code

Recommended remediation for gradle plugin:
pathSet = pathSet.findAll{ it.isDirectory() || it.toString().endsWith('.jar') }
[prior to the join()]

Our specific problem is that hk2-jar (org.glassfish.ha/ha-api/3.1.12/*/ha-api-3.1.12.hk2-jar) is being pulled into our classpath, and it is not an actual jar file.

Any thoughts or possible ways to get some form of command-line editing and/or history working with this?

I would love Emacs keys, but simply having the ability to up-arrow/down-arrow for history, and more importantly left-arrow/right-arrow for inline editing of the command.
