Want to know the correct version of Java for Amazon linux Instance

Hi,

I have cloned Traccar server at my EC2 Instance, everything is going perfect but while making build it's getting failed. So want to know the exact version of Java.

You can find it in the Gradle configuration.

I am getting below error in local terminal.

Plugin [id: 'com.google.protobuf', version: '0.9.4'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Included Builds (No included builds contain this plugin)
- Plugin Repositories (could not resolve plugin artifact 'com.google.protobuf:com.google.protobuf.gradle.plugin:0.9.4')
  Searched in the following repositories:
    Gradle Central Plugin Repository

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
> Get more help at https://help.gradle.org.

That's not the right command. You should be using Gradle wrapper.
