Unable to use JLine from Gradle / Maven #77

Closed vitalyster closed 6 years ago

vitalyster commented 7 years ago

How should I set up Terminal and LineReader when running application from Gradle (./gradlew run)?

vitalyster commented 7 years ago

Under linux I got message: WARNING: Unable to create a system terminal, creating a dumb terminal, under Windows it returns silently

gnodet commented 7 years ago

I suppose gradle creates a new process. In order to run a terminal correctly, this new process needs to inherit the input / output streams of the gradle process itself (that's [doable using java 7](https://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html#inheritIO())).
You need to check the gradle doc if that's possible. I suppose maven has the same problem.

gnodet commented 7 years ago

The exec-maven-plugin uses commons-exec which is still java 1.5 afaik, so it clearly does not support the io inheritance which would be needed. This would require a new plugin.

gnodet commented 6 years ago

Closing this one as it seems to one in gradle or maven is willing to improve the support so that the real terminal can be used.

For anyone else getting here trying to use jline with gradle run -- I found this work-around: https://github.com/tkruse/gradle-groovysh-plugin/blob/master/doc/InstallAppShellManually.md

And then run it with gradle -Porg.gradle.daemon=false --console=plain shell
