# jdtls launcher: the eclipse.jdt.ls project ships no bin/jdtls of its own --
|
|
# every consumer (nvim-jdtls, mason.nvim, coc-java, etc.) hand-writes one, so
|
|
# this mirrors that same well-established convention. Installed at
|
|
# /usr/local/bin/jdtls by the Containerfile so OpenCode's Java LSP
|
|
# integration (which has no auto-download fallback for jdtls, unlike gopls)
|
|
# can find a bare `jdtls` command on PATH.

# same one must be reused across restarts for a given project, and different

|
|
# workspace). Derived from a hash of the real project path and stored under
|
|
# OpenCode's own host-persisted data dir (see the Makefile's DATA_DIR bind
|
|
# mount) so it survives container restarts instead of vanishing with `--rm`.
