I want to import and run Elasticsearch source code into an IntelliJ IDEA project, for that : 1. I have cloned the latest Elasticsearch Source Code from the official Github repository [https://github.com/elastic/elasticsearch](https://github.com/elastic/elasticsearch). `JAVA_HOME` is set to `/home/bhavya/.jenv/versions/11` 2. Then I imported the project into IntelliJ IDEA 3. Now when I run the elastic search from IntelliJ IDEA, using `build.gradle`, following response is generated ```auto 4:41:23 PM: Executing task... > Task :buildSrc:reaper:compileJava > Task :buildSrc:reaper:processResources NO-SOURCE > Task :buildSrc:reaper:classes > Task :buildSrc:reaper:jar > Task :buildSrc:reaper:assemble > Task :buildSrc:reaper:compileTestJava NO-SOURCE > Task :buildSrc:reaper:processTestResources NO-SOURCE > Task :buildSrc:reaper:testClasses UP-TO-DATE > Task :buildSrc:reaper:test NO-SOURCE > Task :buildSrc:reaper:check UP-TO-DATE > Task :buildSrc:reaper:build > Task :buildSrc:compileJava Note: Some input files use or override a deprecated API.

Now according to [CONTRIBUTING.md](https://github.com/elastic/elasticsearch/blob/master/CONTRIBUTING.md#contributing-to-the-elasticsearch-codebase), when I run Elasticsearch using command `./gradlew :run` from the terminal, I get the following errors : **Error** ```auto OpenJDK 64-Bit Server VM warning: Option AggressiveOpts was deprecated in version 11.0 and will likely be removed in a future release.

Error: A fatal exception has occurred. Program will exit. ``` Can anyone help me in resolving this issue? ---
