Looking at the errors, it seems like there is a compilation error which is most probably because of the JDK version, as your JAVA_HOME is pointing to JDK 11.

Here are the ways by which you can resolve the issue :

If you have cloned the latest Elasticsearch source code from https://github.com/elastic/elasticsearch, then to build Elasticsearch, JDK 14 is required. However, since Elasticsearch supports JDK 11, the build supports compiling with JDK 14 and testing on a JDK 11 runtime.
After installing JDK 14, and setting JAVA_HOME pointing to Java home of JDK 14 installation, run Elasticsearch source code with this command again ./gradlew :run.
Once the process is fully started, then run curl in another window like this

curl -u elastic:password localhost:9200

To get a detailed explanation refer this CONTRIBUTING.md

Hey @hacker315 are you able to resolve your issue by installing JDK 14, and pointing your JAVA_HOME to JDK 14
