The ebuild needs to manually specify docs-html-xalan or docs-html-xsltproc as targets before building the default. The appropriate dependencies for whichever is used also needs included. I would recommend going with the xalan version since it is filesystem agnostic as a built-in ant task. Reproducible: Always Steps to Reproduce: 1. Emerge jEdit without having it before. 2. Run jEdit from a console. Actual Results: A FileNotFoundException is emitted. Expected Results: There should be no FileNotFoundException emitted. This means either building the documentation or patching the source code to not load the missing documentation.
Fixed in portage, plus version bumped to pre13.
