[Jython-users] Jython Installer 2.7.1 and Windows error code 14001

[James K. <ji...@sr...>]

Greetings,

We have a maven job which installs Jython, Sphinx, a custom Pygments package we wrote that utilizes a Java library to parse a semantic reasoning language, and all the dependencies so we can generate documentation with color coded and formatted language examples.

FWIW: all of our developers have historically been working on macOS or Linux, and haven’t had a Windows developer in a while (like 2 years).  Anyways this user is getting this error:

[INFO] --- maven-antrun-plugin:1.8:run (install-sphinx-doc) @ sphinx-doc ---

We are running this install with the following Java code:


List<String> installArgs = new ArrayList<String>(Arrays.asList(new String[]{
        "--silent",
        "--directory", jythonHomeDir.toAbsolutePath().toString(),
        "--type", "standard",
        "--include", "mod", "ensurepip",
        "--exclude", "demo", "doc", "src"
}));

org.python.util.install.Installation.main(installArgs.toArray(new String[installArgs.size()]));


I had located this bug report here: http://bugs.jython.org/issue2620

And this note in the Dev Guide…

https://jython-devguide.readthedocs.io/en/latest/setup_jy.html#the-launcher-jython-exe

which doesn’t seem to apply to me as I’m not checking out the source myself…

Is there an updated jython-installer that accommodates this change?  Is there some known workaround I can follow that doesn’t require me to refactor our install?

Thanks,
