出现意外错误（类型=内部服务器错误，状态=500）。 org/eclipse/jdt/internal/compiler/env/INameEnvironment

Question

This is a simple Spring Boot Hello World Example – with JSP. but when I try to access http://localhost:8080/welcome on my browser it gives the following error on my browser.

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
There was an unexpected error (type=Internal Server Error, status=500).
org/eclipse/jdt/internal/compiler/env/INameEnvironment   

------------And in my STS tool throws the following run time error----------

Answer 1

This is one of the annoying error for me. I spent 2 weeks on checking my code, dependencies, and my sts configuration too. There is no single answer on the internet too. The solution for this error is 1. Open my IDE(STS tool) 2. Click on Help from the top menu 3. Select Check for Updates 4. Select all the available updates and Select update, once the update completed 5. Restart my STS Tool, Then right click on my project, go to Maven and select Update project. Now everything works fine as my expectation,

Answer 2

In my case it worked by adding this dependency in pom.xml
It is needed to compile jsp tomcat-embed-jasper version is not working, no idea why
<dependency>
    <groupId>org.eclipse.jdt.core.compiler</groupId>
    <artifactId>ecj</artifactId>
    <version>4.6.1</version>
    <scope>provided</scope>
</dependency>
