Rust is installed now. Great!

To get started you need Cargo's bin directory
(/var/folders/m0/6fmggpxj1vzcp5wjftfx__7r0000gp/T/rust_install_lng2fptu/bin) in
your PATH
environment variable. This has not been done automatically.

Beginne in third_party/ycmd/build.py bei EnableJavaCompleter und dem im Traceback angezeigten DownloadFileTo-Aufruf; untersuche, wie die jdt.ls-URL ausgewählt wird. Überprüfe das Ersatzartefakt oder die Ersatz-URL und führe anschließend python3 install.py --all unter macOS erneut aus. Bestätige, dass die Installation des Java-Completers nicht mehr mit HTTP 404 fehlschlägt.
