hop-cpython's Issues

Edit not working

Screen Shot 2022-07-12 at 1 22 21 PM

Getting this error when simply trying to edit the transform. Is this due to an incompatibility with Hop or with Docker? Currently running the most recent version of Hop in a Docker container, and copied the CPython plugin into the `/usr/local/tomcat/plugins/transforms` directory.

Build Failure Maven

Hi!

The above error message is displayed when performing the mvn clean install command, what would be the solution?

The problem occurs in any directory where the command is run.

thanks!

Hardcoded use of python command

I noticed that there is a hardcoded use of the python command in code, where this should really be based on the user's python command as entered in UI. This can cause issues on systems that use a different version of python by default, for example MacOS and some linux distros will use python for python 2.7 and python3 for python 3+.

This occurs at line 360 and 364 of PythonSession.java.
