Using Eclipse IDE on GuixSD

Using Eclipse IDE on GuixSD

[Mathieu Lirzin]

Hello,

I would like to install the Eclipse IDE on GuixSD for the Java
development I am doing.  I know that despite Ricardo Wurmus hard work,
the Java story is still not shiny on Guix.  As a consequence I don't
expect to be able to build it from source.

Instead, I would like to have a package definition that uses an official
prebuilt tarball [1] as origin.  Does anybody has a custom package
definition in their GUIX_PACKAGE_PATH for doing that?  If not, I will
try to convert the Nix package definition [2] myself.  But I would be
pleased not to have to.

Thanks.

Just in case it interests anyone here is my package definition.
