How to extend the jdt-ls server of eclipse ?

[cmoulliard]

What should we do to extend the jdt-ls of Eclipse to add a bundle (= classes extending the commands) ?
When I run my java LS client and try to execute a delegateCommand (= available from the bundle/plugin) then I got such an error ?

org.eclipse.lsp4j.jsonrpc.ResponseErrorException: No delegateCommandHandler for io.konveyor.tackle.samplecommand

Here is how I added the jar of the bundle

Here is the trick:

Here is the trick to do to add a bundle to the OSGI jdt-ls server. This step is optional as we will pass the bundle path as initialization parameter to the language server !

• Edit the config.ini file corresponding to your architecture: mac, linux, mac_arm under the folder jdtls/config_
• Modify within the config.ini file the osgi.bundles property and include after the org.apache.commons.lang3... jar by example the BundleSymbolicName of the missing jar: java-analyzer-bundle.core-1.0.0-SNAPSHOT.jar

osgi.bundles=...org.apache.commons.lang3_3.14.0.jar@4,reference\:file\:java-analyzer-bundle.core-1.0.0-SNAPSHOT.jar@2,...

• Copy the java-analyzer-bundle.core-1.0.0-SNAPSHOT.jar file from the path jdtls/java-analyzer-bundle.core/ to the plugins folder
