 ```vim
 " Enable completion where available.

-clone the source code repo and then build the plugin:
-
-   ./mvnw clean verify
-
-Note: currently, the build can only run when launched with JDK 8. JDK 9 or more
-recent versions can be used to run the server though.
-
-After build completes the files required to run the language server will be
-located inside the repository folder `eclipse.jdt.ls`. Please ensure to set
-|g:ale_java_eclipselsp_path| to the absolute path of that folder.
-
-You could customize compiler options and code assists of the server.
-Under your project folder, modify the file `.settings/org.eclipse.jdt.core.prefs`
