rebel-readline does not work when compiled with Graal native-image #173

Open dundalek opened 4 years ago

I tried to compile the rebel-readline frontend with Graal native-image in the feature/sci-rebel branch. When running the binary it fails with following error:

May 02, 2020 4:55:07 PM org.jline.utils.Log logr

The reason seems to be that jline3 library tries to load terminal info resources using relative path which graal does not seem to support: https://github.com/oracle/graal/issues/2250.

I tried to change the resource loading to use absolute path in local version of jline. To use the local jline-terminal version I added following into deps.edn:

{:deps
 { ...
  com.bhauman/rebel-readline {:mvn/version "0.1.4"
                              :exclusions [org.jline/jline-terminal]}
  org.jline/jline-terminal {:local/root "/local/path/to/jline3/terminal"}}}

But then I get (I run Java11, not sure why it is trying to pick up 9 profile):

Error building classpath. 1 problem was encountered while building the effective model for org.jline:jline-parent:3.12.2-SNAPSHOT
[ERROR] Failed to determine Java version for profile java9 @

Not sure how can I proceed, I am not very familiar with building maven artifacts.
