Where do I put libraries (jars) if I want to use them in my class?

The only way I managed to make LSP give me autocomplete options for .jars is when I put them inside /workspace/jdt.ls-java-project/lib folder and manually changing /workspace/jdt.ls-java-project/.classpath file to:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
	<classpathentry kind="output" path="bin"/>
	<classpathentry exported="true" kind="lib" path="lib/selenium-api-3.141.59.jar"/>
</classpath>

The problem with this is that the LSP eventually overwrites .classpath file and won’t give me library autocompletion anymore until I manually add it in again. Where do I put my .java and .class files in order for LSP to include them in my editor so I get autocompletion for imports, classes, etc.?

I am using Monaco Editor with monaco-languageclient and custom websocket server that starts an eclipse-jdt-ls.jar and redirects jsonrpc commands to it. Can there somehow be a problem with my configuration?

I’m sorry but I lost it. I used Java to complete a course so I didn’t care about a reliable solution. Eventually I had a folder jdt.ls-java-project in the root of a project, the folder has such .classpath. I remember that later I copied the file from project to project. @rubencaro

I had some experiments on the launch command but I can’t remember why I comment them out.

Hope it helps

Closing since the issue seems been resolved.
