I have a starter spring boot Hello World program, which is throwing the following error:
No Java compiler available for configuration options compilerClassName: [null] and compiler: [null]
I issue is ONLY in Mac and not in windows PC. On my Mac I have tried using both Eclipse and IntelliJ IDEA CE. I have looked at these 2 posts here:
No Java compiler available for configuration options compilerClassName: [null] and compiler: [null]
But these solutions won`t work me.
I am posting my code here: pom.xml

Controller:
package com.mohnish.springbootmaven;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HelloController {
@GetMapping("/")
public String hello() {
return "hello";
}
}
Configuration:
package com.mohnish.springbootmaven;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
public class SpringBootMavenApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SpringBootMavenApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootMavenApplication.class);
}
}
Jsp Page:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello</title>
</head>
<body>
Hello World!
</body>
</html>
and Finally my application.properties:
spring.mvc.view.prefix=/WEB-INF/jsp
spring.mvc.view.suffix=.jsp
I have also tried moving the jsp file to /WEB-INF/ instead of /WEB-INF/jsp.
Any pointer will be appreciated. Thanks.
